Pollen analysis in honey can be used as an alternative method to research into flowers visited by bees in an area. This study aimed to indentify the main floral families in honey from apiaries in the Atlantic Forest and Sergipe state coast. Honey samples from these apiaries were studied, as well as plants that grow around them, which can be used as a source of foraging for bees. The palynological technique was used to compare the pollen content of honey samples with the pollen grains from leaves of plants found in the vicinity of the apiaries to assess whether they had been visited by bees. The results of studies in both sites were similar in terms of incompatibility of families found in the apiary vicinity and honey. Thus, it was possible to observe that in honey samples from the coast and in the remaining Atlantic forest, the number of families was greater than the number of families found in the apiary vicinity, which highlights the diversity of plants visited by bees and a possible expansion of the visited area for food search. This diversity suggests an adaptive foraging behavior to plant resources available in the environment, which may facilitate the pollination of these botanical families and consequently improve their genetic quality.

ABSTRACT The objective of this study was to assess the impact of supplementing quail diets with organic selenium (Se) at various concentrations and inorganic Se on performance, egg quality, and storage time under different conditions. In the performance trial, 360 quail aged 27 weeks were included in a completely randomized design comprising six treatments: Basal Diet; 0.15, 0.30, 0.45, and 0.60 ppm of organic Se; and 0.60 ppm of inorganic Se, supplemented “on top” of the basal diet. Six replications were used, each with 10 birds per experimental unit. For the evaluation of storage time and conditions, 720 quail eggs were employed in a completely randomized design. The design featured a 6×5×2 factorial arrangement consisting of six treatments derived from the performance trial, five storage times (7, 14, 21, 28, and 35 days), and two storage forms (refrigerated and non-refrigerated). Each replication contained one egg, totaling 12 replications. Results indicated no significant effect of organic or inorganic Se supplementation in the diets on performance or egg quality. However, Se concentration increased linearly in eggs from quail fed increasing levels of this nutrient. Selenium supplementation affected storage time and egg quality under refrigerated and room-temperature conditions. In conclusion, on-top Se supplementation at concentrations ranging from 0.15 to 0.60 ppm, whether in organic or inorganic forms, does not impact quail performance. Nevertheless, it leads to increased Se deposition in eggs, contributing to the maintenance of egg quality throughout the storage period.

As formigas cortadeiras estão entre as principais pragas que ocorrem em plantações florestais e agrícolas no Brasil. Esses insetos cortam material vegetal de forma intensa. e posteriormente o transporta para servir de substrato ao cultivo do fungo simbionte. Devido a esse comportamento, várias formas têm sido usadas no seu controle, sendo os inseticidas organossintéticos (sob forma de iscas) os mais utilizados. Contudo, com o uso abusivo destes produtos, impactos negativos no meio ambiente têm ocorrido. Nesse sentido, a busca por métodos alternativos de controle utilizando principalmente produtos de origem vegetal -como os óleos essenciais- tem sido intensificada. O objetivo deste estudo foi avaliar o efeito do óleo essencial de Lippia sidoides em colônias de formigas Atta sexdens mantidas em laboratório, utilizando o método de nebulização. O resultado evidenciou efeito fungicida do óleo essencial de L. sidoides, apontando-o como promissor para ser empregado no controle alternativo de formigas cortadeiras do gênero Atta sp.

Resumo. A tribo Trigonini abrange o maior número de gêneros e espécies de abelhas, existindo espécies que ainda não foram estudadas e características biológicas e ecológicas que ainda são desconhecidas. As abelhas Trigona spinipes (Fabricius) são descritas como agente polinizador de diversas culturas, podendo ser utilizada inclusive como agente polinizador comercial. O objetivo do trabalho foi realizar estudos sobre a abelha T. spinipes, buscando conhecer aspectos de sua biologia, preferências e hábitos alimentares, a partir do acompanhamento dos ninhos existentes no Campus da Universidade Federal de Sergipe, situado na cidade de São Cristóvão, SE. Os seguintes parâmetros foram avaliados: atividade de vôo, estrutura de ninho, umidade, grau brix e pH no mel, e avaliação palinológica do mel e tipos polínicos observados nos ninhos. Foram encontrados 20 ninhos de T. spinipes, as médias de entradas de abelhas foram 298,72 e saídas 282,16. O volume médio dos potes de mel foi de 0,459 mL (p > 0.05), o peso médio de 0,9573 g, (p < 0.01), a umidade igual a 24,20%, o grau brix 74,50 e o pH 3,58. Quanto aos tipos polínicos observados nos ninhos, o grão dominante pertencia à família Celastraceae (46%) e no mel, o grão de pólen dominante pertencia à família Euphorbiaceae (51%). A diversidade de grãos de pólen encontrada em seus alimentos evidencia o potencial da trigona como polinizador. Analysis Melissopalynology and Structure of Nest of Bees Trigona spinipes (Fabricius, 1793) (Hymenoptera: Apidae) Found in the Campus of the Universidade Federal de Sergipe, São Cristóvão, SEAbstract. The tribe Trigonini embraces the largest number of species, a lot of species were not still studied and biological and ecological characteristics are still ignored. The bees Trigona spinipes (Fabricius) are called stingless bees being described as agent pollinator of several cultures could be used besides as agent commercial pollinator. The objective of the work went accomplish studies it remains to bee T. spinipes, looking for to know aspects of its biology, preferences and habits. The study area went at campus of the Federal University of Sergipe, where it was lifted up the number of existent nests, evaluation of flight activity, characterization of the nest, analysis of humidity text, degree brix and pH, besides evaluation palinologyc of the honey and pollen collected in the studied nest. They were found 20 nests, the averages of entrances and exits were, 438.38 and 412.70 in the nest a, 59.45 and 53.43 in the nest two and 398.33 and 380.35 in the nest three. The medium volume of the honey pots was 0,459 mL (p >= 0.05), and the medium weight 0.9573 g, (p

It was evaluated banana weevil infestation in six varieties of banana, in the region of Inhambupe - Bahia, using itself of traps of the type "cheese". The biggest level of infestation occurred in the variety Great Naine, that was statistical significant, with 972 captured insects, average of 7,59 insects/traps. The other varieties presented low index of infestation. With exception of Tap Maeo.

Entre os anos de 2005 e 2007, foram observados mensalmente os danos causados por lagartas sobre as plantas Erythrina velutina (Willd.) no município de São Cristovão, Sergipe, Brasil. As mudas com os danos foram levadas ao laboratório, com o objetivo de caracterizar os danos e identificar a praga. Esta foi identificada como Agathodes designalis (Guenée), encontrada em 35% das plantas em 2005 e 49% em 2007, causando danos da base para o ápice. Este é o primeiro registro de A. designalis atacando E. velutina no Estado de Sergipe, Brasil.
