An outbreak of Rubus stunt disease occurred in a berry production area in South‐West Portugal. Both wild and cultivated blackberry plants showed symptoms. Macropsis spp. (Homoptera: Cicadellidae) are recognized vectors of the phytoplasma responsible for this disease in Rubus plants. Surveys were conducted in 2016, 2017 and 2018 to look for the vector. All Macropsis specimens collected belonged to M. scotti Edwards and evidence suggests that it had a vectoring role in this outbreak. Owing its monophagy on blackberry plants, it is not likely that it will transfer the disease to the raspberry crop, which is far more economically important in the region than blackberry production.

VI Colóquio Nacional da Produção de pequenos frutos. Oeiras, 2021 Apresentam-se os resultados obtidos no GO FruitFlyProtect relativos às capturas de Drosophila suzukii em armadilhas (dispositivo e isco), para estimativa do risco ou para captura em massa. Utilizaram-se os dispositivos das marcas Econex, Koppert, Biobest, com o isco respetivo, e garrafa PET e dispositivo “Lasa”, construídos artesanalmente e iscados com composto de vinagre da empresa Mendes & Gonçalves Lda. Na armadilha “Lasa” usou-se ainda fermento de padeiro como isco adicional. Mais tarde, incluiu-se o dispositivo da Biobest e respectivo isco. A placa vermelha iscada da Econex nunca capturou D. suzukii. A garrafa PET apresentou capturas mais elevadas e a armadilha Koppert a maior especificidade. Expõem-se problemas detetados na identificação de D. suzukii, nomeadamente a possibilidade de confusão entre as formas de inverno desta espécie e as drosófilas do grupo D. obscura. Avaliou-se, também, a eficácia de três espécies de nemátodes entomopatogénicos no combate a D. suzukii: Steinernema carpocapsae, S. feltiae e Heterorhabditis bacteriophora, tendo S. carpocapsae induzido maior mortalidade que S. feltiae em placa de Petri. Não ocorreu mortalidade em pupas. info:eu-repo/semantics/publishedVersion

VI Colóquio Nacional da Produção de pequenos frutos. Oeiras, 2021 Drosophila suzukii (Matsumura) ou “drosófila-da-asa-manchada” é uma espécie que dispensa apresentações, devido aos prejuízos que tem vindo a causar em várias culturas, principalmente nas de pequenos frutos. Tal como aconteceu em 2016, no último Colóquio Nacional de Produção de Pequenos Frutos, faz-se aqui uma atualização do conhecimento sobre esta espécie, através da análise de trabalhos de investigação realizados entre 2016 e 2021. O objetivo é conhecermos melhor a praga e as mais recentes propostas para monitorização e controlo. Pretende-se contribuir para uma produção sustentável de pequenos frutos em quantidade e qualidade e ir ao encontro do interesse dos produtores e consumidores. info:eu-repo/semantics/publishedVersion

The main goal of the project was to generate more information on insect vectors of bacteria and phytoplasmas of phytosanitary concern, more specifically: a) on phloem and xylem feeding insects that should be tested as possible vectors for bacteria and phytoplasmas b) on the fruit and field crop range that the vectored bacteria and phytoplasmas cause damage to c) on the capability of the insects to vector specific bacteria and phytoplasmas of phytosanitary concern d) on the specific association between vector and plant pathogen. The main objectives of the project were to gain insight into the following questions: -Should yet-unknown phloem and xylem feeding insects (Auchenorryncha) be regarded as vectors of the pathogens in selected major crops in Europe? -What monitoring and trapping techniques are optimal to efficiently survey the phloem and xylem feeding insect vectors? -Are there reliable and validated diagnostic tools available to detect/monitor the prokaryotic plant pathogens inside the vectors? -Can we generate extra information on the transmission pathways by monitoring phloem and xylem feeding insect vectors in and around selected infested fields? -Can we generate extra information on the host range of the prokaryotic pathogens by performing vector-transmission trials between different test crops? -Can we reduce the number of treatments of pesticides due the better understanding of relation vector/pathogen/environment and thereby enable a better integrated management of vectors and diseases in the crops., Report of the Euphresco project 2015-D-168 'Tracking vectors of bacteria and phytoplasmas threatening Europe's major crops (VECTRACROP)'

- Abstract
In agroecosystems, the evaluation of biodiversity is extremely important given its relation with their sustainability, however it is a difficult and expensive task. The use of the higher taxa surrogacy has been proposed as an effective and less expensive way to assess biodiversity, but is still being used mainly in natural, more stable, ecosystems. In this study, we tested the use of the higher taxa surrogacy approach for spiders in pear orchards, under different production systems, in the Oeste region of Portugal. Spiders were chosen for this case study, since they are important predators, acting as biological control agents in agroecosystems. We concluded that genus can be used as a highertaxasurrogate of species richness with a good accuracy., Em ecossistemas agrícolas, a avaliação da biodiversidade é extremamente importante dada a sua relação com a sustentabilidade, sendo contudo uma tarefa difícil e dispendiosa. O uso da relação entre o número de espécies e o número de táxones de alto nível, tem sido proposto como uma alternativa eficaz e económica para a avaliação da biodiversidade, contudo a sua utilização tem estado praticamente restringida aos ecossistemas naturais, mais estáveis. Neste estudo, testou-se o uso da relação entre o número de espécies e o número de táxones de alto nível em aranhas, em pomares de pêra sob diferentes modos de produção, na região Oeste de Portugal. As aranhas foram seleccionadas para este estudo de caso por serem importantes predadores, actuando como agentes de luta biológica contra pragas. Concluiu-se que o género pode ser usado na avaliação da riqueza de espécies, com um elevado grau de precisão.

Coenosia attenuataStein, ou mosca tigre, predador polífago de importantes pragas agrícolas, enquanto larva e adulto, foi detectado em Portugal, pela primeira vez, em 2002, no Oeste. Para optimização da sua criação em massa, alteraram-se metodologias descritas na bibliografia. Ocorreu maior número de emergências em substratos com maior número de larvas de esciarídeos e em substrato de terra misturado com fibra de coco. Estudou-se, em laboratório, o seu comportamento e capacidade de predação sobre várias espécies, incluindo parasitóides e predadores importantes em culturas protegidas, tendo predado todas as espécies testadas:Diglyphus isaea,Trialeurodes vaporariorum,Liriomyza huidobrensis, Drosophila melanogaster,Eretmocerus mundus,Nesidiocoris tenuis,Orius laevigatus, Dacnusa sibirica,Pseudococcus viburni,Tuta absolutae algumas espécies de Psycodidae. Observaram-se indícios de preferência alimentar das fêmeas de mosca tigre por moscas brancas e larvas mineiras, em relação a diglifos, e diferenças no comportamento de predação sobre moscas brancas em presença de larvas mineiras ou drosófilas., Coenosia attenuataStein, or tiger-fly, a polyphagous predator of important agricultural pests, as larva and adult, was detected for the first time, in Portugal, in 2002, in the Oeste region. For mass rearing optimization, the methodologies described in literature were changed. A higher number of emergences occurred on substrates with higher number of sciarids larvae and on the substrate with soil mixed with coconut fiber. The predation capacity and behaviour ofC. attenuatawas studied in laboratory in relation to several species, including parasitoids and predators with an important role in protected crops. All species tested were predated:Diglyphus isaea,Trialeurodes vaporariorum,Liriomyza huidobrensis, Drosophila melanogaster,Eretmocerus mundus,Nesidiocoris tenuis,Orius laevigatus, Dacnusa sibirica,Pseudococcus viburni,Tuta absolutaand some Psycodidae species. There was evidence of female preference for whiteflies and leafminers in relation toDiglyphus isaea, as well as predation behaviour differences over whiteflies when leafminers or drosophilids were present.

Faba bean (Vicia fabaL.) that is grown world-wide as a protein source for food and feed also offers ecosystem services such as N2fixation and enhancement of wild fauna diversity such as bee-pollinators and other beneficial organisms. Thus, it helps to mitigate the pollinator decline and it is recognized that also contributes to pest control not only in the crop itself but also in the neighbouring/associated crops by attracting predators and parasitoids. Despite this importance, the global faba bean cultivation area has declined due to its low yield performance and susceptibility to biotic and abiotic factors. To face these constraints, it is relevant to implement adequate breeding programs using the available germplasm and always taking in consideration the pollination and mating system of faba bean. The aim of this paper is 1) to review the role of faba bean in cropping systems; 2) to assess the applicability of different molecular markers to understand the genetic diversity of faba bean germplasm; 3) to analyse the role of pollination and the mixed-mating system underpinning breeding strategies; 4) to assess the natural enemies affecting faba bean and to analyse the genetic sources of resistance to them., A faveira (Vicia fabaL.), cultivada mundialmente, é uma importante fonte de proteína na alimentação humana e animal. Tem também um papel relevante em serviços do ecossistema, como na fixação do N2e no aumento da diversidade dos polinizadores e outros auxiliares. Contribui, deste modo, para impedir o declínio dos polinizadores e, ao atrair predadores e parasitoides, contribui para o controlo de pragas nesta cultura e nas culturas vizinhas. Apesar de ser reconhecida a sua importância nos sistemas agrários, a área cultivada tem diminuído, a nível mundial, como consequência da sua baixa produtividade e suscetibilidade a fatores bióticos e abióticos. Para ultrapassar estes constrangimentos é fundamental implementar programas de melhoramento adequados, utilizando o germoplasma existente e atendendo sempre ao facto da faveira ser parcialmente alogâmica. Este trabalho tem como objetivos: 1) rever o papel desempenhado pela faveira nos sistemas culturais; 2) avaliar a aplicabilidade de diferentes marcadores moleculares no estudo e compreensão da sua diversidade genética; 3) analisar o papel dos polinizadores nas estratégias de melhoramento; 4) avaliar os inimigos naturais que afetam a faveira e analisar as fontes de resistência existentes.

Dissertação de Mestrado apresentada ao ISPA - Instituto Universitário A teoria de Fisher (1930) sugere que, para a maioria das espécies, o investimento dos progenitores no cuidado parental é igual para ambos os sexos das crias, permitindo deste modo um equilíbrio do rácio sexual na natureza de 1:1. No entanto, Trivers e Willard (1973) verificaram que em algumas espécies os progenitores em priores condições investem maioritariamente no sexo que exige um menor gasto energético. Ainda que ao longo dos anos tenha havido um aumento na investigação sobre a alocação do sexo em aves, há ainda muito por descobrir sobre os fatores que a influenciam. Usando um estudo de longo-prazo sobre a cagarra Calonectris diomedea borealis, testou-se se há uma alocação do sexo relativamente à idade parental e ao sucesso reprodutor passado. O estudo realizou-se em 2014 na ilha Selvagem Grande. Recolheram-se 208 amostras de sangue a crias, sendo possível determinar o sexo de 158 indivíduos por análise molecular. A análise estatística revelou existir dimorfismo sexual nas crias, sendo os machos mais pesados. Adicionalmente a este facto, o volume e a forma dos ovos não aparentam estar relacionados com o sexo da cria, nem com a idade dos progenitores. Não se encontraram indícios de alocação sexual relativamente à idade ou ao sucesso reprodutor passado (reflectindo qualidade) dos progenitores. Conclui-se, portanto, que o investimento diferencial em crias machos ou fêmeas, em função do estado dos progenitores, não é uma característica universal em espécies dimórficas e não se aplica à cagarra, sendo, contudo, desejável estudar este aspecto em anos com condições ambientais contrastantes. ABSTRACT: Fisher’s theory (1930) suggests that for most species the parental effort in the care of the offspring is the same for both sexes, allowing a natural ratio of 1 to 1. However, Trivers and Willard (1973) found that in some species, individuals in poorer condition may invest in the sex that requires less energy. Over the years there has been an increase in research on the allocation of the bird´s sex. Despite this, there are still knowledge gaps that must be fulfilled). Using a long-term study of Calonectris diomedea borealis, we tested if parental age and past breeding success (reflecting quality) influenced the choice of the sex of the offspring. The study took place in 2014 at Selvagem Grande island. 208 blood chicks’ samples were collected, being possible to determine the gender of 158 subjects. Statistical analysis showed there is sexual dimorphism in chicks, with males being heavier. The volume and shape of the eggs are not related to the sex of the offspring, or with the age of the parents. The age of the male and of the female parent, and their past breeding output (reflecting individual quality) did not influence the sex of the offspring. In conclusion, the differential investment in male or female offspring in relation to parental state or condition is not an universal feature amongst birds and does not apply to the present species, although more data from years with contrasting environmental conditions are desirable.

- Abstract
Legumes are bee-pollinated, but to a different extent. The importance of the plant–pollinator interplay (PPI), in flowering crops such as legumes lies in a combination of the importance of pollination for the production service and breeding strategies, plus the increasing urgency in mitigating the decline of pollinators through the development and implementation of conservation measures. To realize the full potential of the PPI, a multidisciplinary approach is required. This article assembles an international team of genebank managers, geneticists, plant breeders, experts on environmental governance and agro-ecology, and comprises several sections. The contributions in these sections outline both the state of the art of knowledge in the field and the novel aspects under development, and encompass a range of reviews, opinions and perspectives. The first three sections explore the role of PPI in legume breeding strategies. PPI based approaches to crop improvement can make it possible to adapt and re-design breeding strategies to meet both goals of: (1) optimal productivity, based on an efficient use of pollinators, and (2) biodiversity conservation. The next section deals with entomological aspects and focuses on the protection of the “pest control service” and pollinators in legume crops. The final section addresses general approaches to encourage the synergy between food production and pollination services at farmer field level. Two basic approaches are proposed: (a) Farming with Alternative Pollinators and (b) Crop Design System.

Coenosia attenuata Stein, or “tiger-fly”, a polyphagous predator of important agricultural pests, as larva and adult, was detected for the first time, in Portugal, in 2002, in the “Oeste” region. For mass rearing optimization, the methodologies described in literature were changed. A higher number of emergences occurred on substrates with higher number of sciarids larvae and on the substrate with soil mixed with coconut fiber. The predation capacity and behaviour of C. attenuata was studied in laboratory in relation to several species, including parasitoids and predators with an important role in protected crops. All species tested were predated: Diglyphus isaea, Trialeurodes vaporariorum, Liriomyza huidobrensis, Drosophila melanogaster, Eretmocerus mundus, Nesidiocoris tenuis, Orius laevigatus, Dacnusa sibirica, Pseudococcus viburni, Tuta absoluta and some Psycodidae species. There was evidence of female preference for whiteflies and leafminers in relation to Diglyphus isaea, as well as predation behaviour differences over whiteflies when leafminers or drosophilids were present.

The insects present in the blackberry and blueberry crops are still almost unknown in Portugal. Thrips and their natural enemies were surveyed in these crops, during the flowering period, in Odemira region, as well as in the weeds inside and around the crops areas. This allows an evaluation of the entomological interaction cropweeds, for a future management of weeds taking also into account crops protection against pests. The preliminary results obtained are presented. Thrips flavus and T. tabaci were the most abundant thrips in the crops. Weeds where Thrips sp. adults were more abundant were Arctotheca calendula, Crepis capillaris, Senecio gallicus, Geranium molle, Malva parviflora, Lavatera cretica and Lupinus luteus. In this last weed species, Aeolothrips spp. predators were abundant. The heteropterans Orius sp., predators of thrips, were detected in the blackberry crop, and also on Conyza bonariensis, Conyza sumatrensis, Sonchus tenerrimus and Echium plantagineum

horticolas ,bemisia tabaci ,virus ,vegetable crops - Abstract
In Portugal, Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) was first recorded in 1992, in horticultural crops. Since 1995, it has been an important pest in the Algarve, southern Portugal, where it is present the whole year round, in greenhouse crops, with high infestations during the summer. In 2006, it was installed in Alentejo and in part of Ribatejo e Oeste region. It is a serious problem to several vegetable crops, due to direct damages, but mainly by transmitting plant viruses. The most severely affected crops are greenhouse tomato and cucurbits. IPM is considered the best way to deal with the sustainable management of this problem, but the presence of viruses complicates the implementation of IPM programs. The work presented here gives an overview of the results obtained by the research activities carried out in Portugal concerning B. tabaci: geographical distribution, bioecology, biotypes identification, virus transmission, risk assessment, natural enemies’ survey and control methods. Future research work is suggested.

Em Portugal, Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) foi detectada pela primeira vez em 1992, em culturas hortícolas. Desde 1995, é uma praga importante no Algarve, onde está presente nas estufas durante todo o ano, com níveis de infestação elevados no Verão. A partir de 2006, foi considerada também estabelecida no Alentejo e em parte do Ribatejo e Oeste. A espécie constitui um grave problema em diversas culturas hortícolas, não só pelos prejuízos directos, mas, principalmente, pela sua capacidade de transmitir vírus de plantas. As culturas mais atacadas são as de tomate e de cucurbitáceas, em estufa. A protecção integrada é a melhor forma de minorar este problema de modo sustentável, embora a presença de vírus dificulte a respectiva implementação e sucesso. Neste trabalho, apresentam-se os resultados da investigação desenvolvida em Portugal sobre esta espécie, nomeadamente: distribuição geográfica, bioecologia, identificação de biótipos, transmissão de vírus, estimativa do risco, prospecção de auxiliares e meios de luta. Sugerem-se ainda futuras linhas de trabalho., In Portugal, Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) was first recorded in 1992, in horticultural crops.

The work presented here gives an overview of the results obtained by the research activities carried out in Portugal concerning B. tabaci: geographical distribution, bioecology, biotypes identification, virus transmission, risk assessment, natural enemies survey and control methods. Future research work is suggested.

The tiger-fly Coenosia attenuata is a globally widespread predatory fly which is not only associated with greenhouse crops, but also occurs in open fields. It is a potential control agent against some of the more common pests in these crops. Assessing the genetic structure and gene flow patterns may be important for planning crop protection strategies and for understanding the historical processes that led to the present distribution of genetic lineages within this species. In the present study, the phylogeographical patterns of this species, based on mitochondrial cytochrome oxidase I and nuclear white and elongation factor-1α genes, are described, revealing relatively low genetic diversity and weak genetic structure associated with a recent and sudden population expansion of the species. The geographical distribution of mitochondrial haplotypes indicates the Mediterranean as the most likely region of origin of the species. Some dispersal patterns of the species are also revaled, including at least three independent colonizations of North and South America: one from Middle East to North America with a strong bottleneck event, another from Europe to South America ( Chile), with both likely to be a result of unintentional introduction, and a third one of still undetermined origin to South America ( Ecuador). © 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, 114, 308-326.

Mestrado em Engenharia Agronómica - Hortofruticultura e Viticultura - Instituto Superior de Agronomia - UL O estudo desenvolvido nesta dissertação teve como principais objetivos identificar as espécies de tripes (Thysanoptera: Thripidae) presentes na cultura da cebola e estudar a evolução das suas populações, ao longo do ciclo fenológico desta cultura. A monitorização dos tripes decorreu de 19 de abril a 1 de agosto de 2016, em três campos no Ribatejo. Em cada campo observaram-se, semanalmente, quatro armadilhas cromotrópicas adesivas, duas amarelas e duas azuis. Adicionalmente, recolheu-se uma amostra de 15 plantas de cebola, em cada um dos campos, na fase inicial de formação do bolbo e ainda foram capturados pontualmente tripes nas plantas, no campo. Nos três campos de cebola estudados, verificou-se uma tendência para um gradual aumento do número de tripes, principalmente a partir da segunda quinzena de junho. Quanto à diversidade de tripes capturados nas armadilhas, foram detetados 12 géneros pertencentes à subordem Terebrantia e, ainda, indivíduos da subordem Tubulifera. Os três géneros que mais se destacaram pela sua abundância foram Thrips, Frankliniella e Aeolothrips. Foram identificadas as seguintes espécies: Chirothips manicatus Haliday, Chirothips aculeatus Bagnall, Frankliniella occidentalis (Pergande), Frankliniella tenuicornis (Uzel), Isoneurothrips australis Bagnall, Limothrips cerealium Haliday, Thrips tabaci Lindeman, Thrips angusticeps Uzel, Tenothrips frici (Uzel). Relativamente aos tripes recolhidos nas plantas de cebola, verificou-se uma diversidade mais baixa, em relação às armadilhas, e uma clara dominância de T. tabaci, vulgarmente designado por tripe-da-cebola, com 96,1% dos tripes capturados. Os resultados sugerem que as outras espécies de tripes detetadas nas armadilhas estariam associados às adventícias existentes em abundância nos campos em estudo e não às plantas da cultura. Apenas para o género Aeolothrips se detetou a presença de mais machos do que fêmeas, tanto nas armadilhas amarelas como nas azuis; em todos os restantes táxones analisados detetou-se a presença de mais fêmeas do que machos. Analisou-se a preferência de diferentes géneros/ espécies pela cor de armadilha, amarela e azul. A espécie T. tabaci mostrou preferência pelo azul N/A

Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia - UL O presente trabalho teve como objetivo estudar, a diversidade e abundância de tripes, associados a três parcelas de limoeiro na região de Mafra, através de duas técnicas de captura, e avaliar o grau de presença de Pezothrips kellyanus (Bagnall), de forma a compreender a sua evolução naquela região. Foi identificado um total de 1797 tisanópteros, dos quais 1793 pertenciam à subordem Terebrantia, e apenas quatro à subordem Tubulifera. Quanto ao tripes da subordem Terebrantia, registaram-se 11 géneros e duas famílias. A família Thripidae foi a mais abundante, representando 92,9% dos indivíduos identificados, sendo que os restantes pertenciam à família Aeolothripidae (7,1%), género Aeolothrips. Entre os géneros presentes da família Thripidae, destacaram-se Thrips (64,4%), Pezothrips (19,5%), e Frankliniella (6,5%). Pela técnica das pancadas, aplicada às flores, foram identificados 586 exemplares, pertecentes a cinco géneros e oito espécies. As três parcelas revelaram diferenças substanciais entre elas, tanto a nível de abundância como de diversidade de espécies. P. kellyanus predominou apenas na Parcela 1 (82,6%), tendo sido Frankliniella occidentalis (Pergande) a espécie mais representada na Parcela 2 (72,1%). Thrips flavus Schrank foi a espécie mais abundante na Parcela 3 (43,5%), seguida de P. kellyanus (32,9%). Foram identificados 1211 indivíduos no conjunto das armadilhas cromotrópicas adesivas. Dos 11 géneros detetados por este método de amostragem, Thrips predominou nas três parcelas (85,9%, 79,1% e 80,4%). Na Parcela 1 o segundo género mais representado foi Pezothrips (5,5%), ao passo que nas Parcelas 2 e 3 o segundo género detetado com maior abundância foi Aeolothrips (8,9% e 12,9%, respetivamente). Foi detetada uma presença significativa de Frankliniella na Parcela 2 (8,5%). Por comparação com a última amostragem realizada, em 2003 (Costa et al., 2006), nesta região e salvaguardando os diferentes métodos de amostragem utilizados, Pezothrips revelou um aumento significativo na sua abundância.

Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia The objectives of this study were to identify: (1) the most abundant thrips species in blackberry, blueberry and strawberry crops, comparing its abundance between cultivars and crop plants localization; (2) weed species that may contribute to the presence of thrips and auxiliary insects in the crops. Thrips samples were taken from the crops and weeds using beating and washing methods. Thrips tabaci Lindeman was detected in the majority of the plants and this species was one of the most abundant species in the three crops. Thrips flavus Schrank was the most abundant species in blackberry and blueberry crops. Drepanothrips reuteri Uzel was only found in blackberry plants. Frankliniella occidentalis (Pergande) might have been introduced when the strawberry crop was planted. Lavatera cretica L., Lupinus luteus L. and Sinapis alba L. may bring risks to the crops, because they are possible repositories of T. flavus and T. tabaci. Arctotheca calendula (L.) Levyns, Crepis capillaris (L.) Wallroth, Geranium dissectum L., Geranium molle L., Leontodon sp., Malva parviflora L., Senecio gallicus Chaix and Poaceae plants were identified as possible repositories of thrips, which might serve as alternative preys to auxiliary insects. Aeolothrips Uzel (Thysanoptera) and Orius Wolff (Hemiptera) species, referred as thrips predators, were identified.

Diglyphus isaea ,tiger-fly ,whiteflies ,Coenosia attenuata ,predation ,leafminers - Abstract
Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia The aim of this study was to evaluate prey preferences of Coenosia attenuata Stein (commonly known as tiger-fly), amongst species, pests or beneficials, common in Portuguese agricultural ecosystems, namely in protected crops, whiteflies, leafminers, and Diglyphus isaea (Walker), and Drosophila (Soophophora) melanogaster Meigen. This goal was achieved in two different assays evaluating in both cases a pair of prey species at each time: (i) 24 hours tests at the end of which the number and proportion of preyed individuals, dead of unknown causes individuals and alive individuals were assessed; (ii) first capture tests in which the insect preyed at the first place, between two available preys, was registered. Food preference behavior was detected in both assays being whiteflies and leafminers preferred to the diglyphus. When analyzing the combination leafminers versus whiteflies and drosophila versus whiteflies, differences in predation were registered between leafminers and drosophila, against whitefly being the whiteflies less predated in the presence of leafminers

Diglyphus isaea ,Coenosia attenuata ,predation ,rearing - Abstract
Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia Coenosia attenuata Stein (Diptera: Muscidae) is a species that belongs to the tigrina group. It is considered as a generalist predator of agricultural pests in both larval and adult stages. In this work, rearing methods developed by other authors were adapted/ changed in order to improve mass production of this predator. There were more emergences occurring in substrates with larger number of sciarid larvae and in cages with more than five parental couples. Those collected in the field showed higher emergence rates in the next generation when compared with laboratory-reared individuals. Regarding rearing substrate optimization, the highest number of emergences was observed in the substrate constituted by a mixture of soil and coconut coir. In the absence of pests as preys, C. attenuata may attack beneficial insects. An evaluation of the consumption rates over Diglyphus isaea Walker was also made. D. isaea is a common parasitoid relevant in greenhouse systems in Portugal. Mated adult females of C. attenuata showed higher predation rates over D. isaea than other female categories tested; females captured more individuals (11 per day on average) than males (7 per day on average) and were also more voracious on prey consumption.
