ABSTRACT
Abstract Rhynchophorus ferrugineus (RPW) (Olivier) (Coleoptera Curculionidae) is one of the most destructive pest of palm according to dozens of literature, a lot of effort have been made since three decades up to date to solve this problem, one of newest solution raised is using nano pesticides. Imidacloprid and Chloropyrophos and their nano form were tested against 10 days-old larvae and newly emerged adults of the red palm weevil. The pesticides had toxicological and pathological effects on Rh. ferrugineus larvae and adults. The toxicity effect of nano chloropyrophos was more than others. The damage included vaculation of cytoplasm, analyzes and destroyed nuclei of the epithelial cells. The larvae were more sensitive in the total damages in comparison with adults. This investigation is the first record to the histopathological effects of nano pesticides.
RESUMO
Resumo Rhynchophorus ferrugineus (RPW) (Olivier) (Coleoptera Curculionidae) é uma das pragas mais destrutivas da palmeira, de acordo com dezenas de publicações, muito esforço foi feito desde três décadas para resolver esse problema, uma das mais recentes soluções levantados está usando nano pesticidas. O imidaclopride e o cloropirofós e sua nano forma foram testados em larvas com 10 dias de idade e em adultos recém-emergidos do gorgulho da palma vermelha. Os pesticidas tiveram efeitos toxicológicos e patológicos em Rh. larvas de ferrugineus e adultos. O efeito da toxicidade dos nano cloropirofos foi maior que outros. O dano incluiu a vacinação do citoplasma, análises e núcleos destruídos das células epiteliais. As larvas foram mais sensíveis no total de danos em comparação com os adultos. Esta investigação é o primeiro registro dos efeitos histopatológicos dos nano pesticidas.
