Chagas disease is one of the most important public health problems in America, involving triatomines (Hemiptera: Reduviidae: Triatominae) in the vectorial transmission of Trypanosoma cruzi (Protista: Kinetoplastea: Trypanosomatidae). In Argentina, 15 species of triatomines are distributed, of which seven are the most common in the domicile and peridomicile, while the rest are mainly associated with wild environments. Due to the lack of updated data of geographic distribution, the GeoVin Project arises to provide not only a triatomine digital tool of triatomine notification, but also resources with information about Chagas and triatomine vectors. The aim of this paper is to present, describe and highlight the progress of the project, emphasizing the principles of participatory science and entomological surveillance. So far, more than 2,300 web visits have been recorded and the application has been downloaded over 3,400 times. The contribution of the project in articulating with the corresponding government health agencies and the immediacy of the interaction with the community are key elements for the project success. At the same time, the information collected is a constant input for updating the geographical distributions of Argentinian triatomines. [ABSTRACT FROM AUTHOR]

In this paper, a historical survey of the development of the entomological studies in Argentina from the 18th century to 1925, the year in which the Sociedad Entomológica Argentina was created, is presented. Three periods are distinguished in this historical survey: (a) research on insects in colonial and early independent Río de la Plata, and in early Argentina until the 1870s; (b) the period from c. 1870 to c. 1900, in which entomology functioned as a core around which much of the zoological studies were organized; (c) the period from c. 1910 to c. 1925, which involved the development of large entomological collections in the Argentine Museum of Natural Sciences (Buenos Aires) and the Museum of La Plata, the beginnings of applied entomology with the hiring of French and American specialists, and the incorporation of women in the field.

Specimens were collected in the localities Magdalena, Mar Chiquita and Mar del Plata. [ABSTRACT FROM AUTHOR]

Acrotomopus atropunctellus (Boheman) (Curculionidae: Molytinae: Cholini) is a weevil species endemic to Argentina, mainly inhabiting the biogeographic province of the Yungas. It was first reported as harmful to sugar cane in 1929. Damages were not cited again until a decade ago, when the species became a serious pest due to the increased sugar cane production. This species is morphologically similar to A. wagneri Hustache that occurs in the Chacoan biogeographic province. Its biology resembles that of other species of Cholini whose larvae mine inside long-stemmed plants. Females lay eggs in the basal and middle portions of young plants. Larvae feed inside the stems and reach the stumps by winter, reducing the reshooting capacity of cane in subsequent growth seasons. Adults produce small holes with irregular borders in buds, stems and central veins of leaves. We provide a key to separate A. atropunctellus from the remaining three species of Acrotomopus, A. wagneri, A. microspilotus (Pascoe) and A. obtusus (Hustache), all of them occurring in Argentina. We also give details about the main features of its biological cycle and the damages caused to sugar cane in Tucumán province. The paper includes illustrations of the four Acrotomopus species and of the larvae and damages produced by A. acropunctellus. [ABSTRACT FROM AUTHOR]

Despite their prevalence in human corpses during decomposition, Sarcophagidae are not frequently used in forensic studies due to the difficulty in their identification and to the lack of information on their biology. In this paper, we identified the species of Sarcophagidae associated to corpses and studied their relationship to decomposition stages. We analyzed preferences for different cadaveric substrates (pig and lama) and microenvironmental conditions (shade, sun) at a site located at 3600 m.a.s.l. during the spring. Two pig carcasses, one located in the shade and the other in the sun, and a third carcass of a lama located in the sun, were used. We collected 597 individuals belonging to five Sarcophagidae species: Microcerella antofagastensis Mulieri, Mariluis & Aballay (n=347), M. quimaliensis (Lopes) (n=117), M. rusca (Hall) (n=32), M. penai (Lopes) (n=5) and M. aulacophytoPape (n=96). Both M. antofagastensis and M. quimaliensis were the effective colonizers and represented 78% of the total adults collected. Microcerella antofagastensis was the primary colonizer. Both species had a similar response against microenvironmental conditions and both preferred the pig carcass. We discuss the importance of these two species as forensic indicators and the advantages of ovoviviparity against other oviparous species under extreme arid conditions. [ABSTRACT FROM AUTHOR]

This paper discusses the insecticidal effect of volcanic ash and its environmental impact, focusing on the ash accumulated as a result of the eruption of the volcanic complex Puyehue- Caulle Range currently affecting an area of over 7.5 million hectares in the Argentine Patagonia. The chemical composition of ashes from the Puyehue-Caulle Range was analyzed by EDS showing that its major components are O, Si, A\, Fe, Na and K. Laboratory bioassays using two species of insects as a biological model, found that the ashes thoroughly adhere to the insect body surface and are toxic to both species tested, when mixed into the substrate at low concentrations. Susceptibility to ashes differs between the two species when tested in a seven day continuous exposure bioassay [CL99Oryzaephilus surinamensis L.) = 10.25 mg.g-1; CL99((Tribolium castaneum (Herbst)) = 4.96 mg.g-1]. These results agree with those reported in the literature on effects of volcanic eruptions and suggest that the impact of the ashes from the Puyehue-Caulle Range volcanic complex on the insect community may be radical in the acute deposition phase, with substantial qualitative effects in the chronic phase of exposure. Also, the recovery of populations affected by ash in desert areas where dry ash persists will be slower, and this will have tangible and long-term consequences for insect host plants, pollination and on the development of populations of vertebrate insectivores. By contrast, the presence of ash in humid regions will impact the ecosystem by the addition of nutrients, which in combination with water retention by the ash will lead to a qualitative and quantitative recovery of the populations under favorable conditions.

The Odonata order is represented in Patagonia by 36 species belonging to nine families and 18 genera. The endemicity level is high being approximately 60% of the species and 40% of genera endemic. The specific richness in Patagonia decreases from West to East and from North to South, being Nahuel Buta (Chile) and Andes mountains between 38° and 41° S on the forest area, and the Somuncurá plateau (Argentina) on the steppe the richest areas. An update of its records and an analysis of the main distribution patterns are provided in this paper. [ABSTRACT FROM AUTHOR]

The objective of this paper is to report new records of species of the genus Eretmocerus Haldeman, parasitoids of the most important whitefly pest species in vegetables and ornamental crops in Argentina. One species was found parasitizing Trialeurodes vaporariorum (Westwood) in Santa Fe and Buenos Aires provinces and it is grouped into californicus group near corni Haldeman, due to its morphological characters. It could be a new species. The known distribution of Eretmocerus mundus Mercet, a parasitoid of Bemisia tabacs (Gennadius), is enlarged to include the provinces of San Juan and Buenos Aires of Argentina.
