Última Differences in wing melanization and pigmentation pattern in Drosophila buzzatii (Diptera: Drosophilidae) under chemical stress Rev. Soc. Entomol. Argent. Mongiardino Koch,Nicolás; Hasson,Esteban; Soto,Ignacio M.. Recently, the genetic basis and developmental mechanisms underlying the process of melanization have become progressively elucidated, allowing us to study the evolutionary processes that govern the huge variability of pigmentation observed in nature. However, environmental factors contributing to such variability have received little attention, even though they might have profound ecological consequences. Here we describe a method for analyzing the wing melanization patterns of drosophilids in both qualitative and quantitative ways. We test this method on wings of Drosophila buzzatii Patterson & Wheeler individuals, reared in control and alkaloid-enriched mediums. The alkaloids were extracted from the secondary host of these flies, Echinopsis... Tipo: Info:eu-repo/semantics/article Palavras-chave: Drosophila buzzatii; Melanin; Ecotoxicology; Alkaloids; Stress.

Soc. Entomol. Argent. Lavagnino,Nicolás J.; Carreira,Valeria P.; Mensch,Julián; Hasson,Esteban; Fanara,Juan J.. The first published record of the African drosophilid Zaprionus indianus Gupta 1970 in the Americas refers to individuals observed on fallen persimmon (Diospyros kaki Linnaei, «caqui») fruits in São Paulo city (Brazil) in March 1999. Since that date, this species colonized altered and natural environments across the continent. In the present work we report new records for Z. indianus in north eastern Argentina. Moreover, our results showed that this species represents a fairly high proportion among collected drosophilids in some sampling sites. Our survey also revealed that this invading species has the ability to breed and feed in a wide range of native and cultivated host-plants.
