Última Insecticide resistance in Argentine populations of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) Neotropical Entomology Lietti,Marcela M.M.; Botto,Eduardo; Alzogaray,Raúl A.. The tomato leafminer, Tuta absoluta (Meyrick), is one of the key pests of tomato in Argentina. Since its dispersal in the 1970s, chemical control has been the main method of controlling it. However, reduced efficacy of some of the recommended insecticides has been observed since the 1980s. The aim of this work was to study the toxicity of three insecticides widely used in chemical control of T. absoluta (abamectin, deltamethrin and methamidophos) on larvae from a laboratory susceptible population (CASTELAR) and two greenhouse populations (ROSARIO and BELLA VISTA). Insecticides were dissolved in acetone and topically applied to the mid-dorsal abdominal region of two-day old 4th instar larvae. LD50 values were estimated and the Resistance Ratio (RR) for each...

Rev. Soc. Entomol. Argent. Haramboure,Marina; Reguilón,Carmen; Alzogaray,Raúl A.; Schneider,Marcela Inés. Chrisopids are economically significant predators of several agricultural pests. In Argentina, the species recorded of Chrysoperla Steinmann, 1964 are C. externa (Hagen, 1861), C. asoralis (Banks, 1915), C. argentina (González Olazo &amp; Reguilón, 2002) and C. defreitasi (Brooks, 1994). Chrysoperla asoralis and C. argentina have been associated with citric, olive, maize and cotton crops. In the present note, we record for the first time these two species in La Plata and neighboring areas within the Buenos Aires province, in association with the sweet pepper, Capsicum annuum L.

Soc. Entomol. Argent. Russo,Romina; Gamundi,Juan C.; Alzogaray,Raúl A.. Soybean is the most important crop in Argentina and Rachiplusia nu (Gueneé) (Lepidoptera: Noctuidae) is one of its main pests. In this study, the toxicity of five pyrethroids applied topically and by exposure to films on filter paper was evaluated on third instar larvae from a laboratory strain and a field population of R. nu. Four cyanopyrethroids and one non-cyanopyrethroid (permethrin) were tested. All cyanopyrethroids showed the same order of increasing toxicity, regardless of the form of application and origin of the larvae: cypermethrin < ?-cyhalothrin < deltamethrin < ß-cyfluthrin. Knock down Dose 50% and Knock down Time 50% values increased as a function of the solubility of cyanopyrethroids in water. Permethrin showed a different...
