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. Keywords: nano chloropyrophos, nano Imidacloprid, histopathology, pesticide effect Rhynchophorus ferrugineus. Rhynchophorus ferrugineus (RPW) (Olivier) (Coleoptera: Curculionidae) e uma das pragas mais destrutivas da palmeira, de acordo com dezenas de publicacoes, muito esforco foi feito desde tres decadas para resolver esse problema, uma das mais recentes solucoes levantados esta usando nano pesticidas. O imidaclopride e o cloropirofos e sua nano forma foram testados em larvas com 10 dias de idade e em adultos recem-emergidos do gorgulho da palma vermelha. Os pesticidas tiveram efeitos toxicologicos e patologicos em Rh. larvas de ferrugineus e adultos. O efeito da toxicidade dos nano cloropirofos foi maior que outros. O dano incluiu a vacinacao do citoplasma, analises e nucleos destruidos das celulas epiteliais. As larvas foram mais sensiveis no total de danos em comparacao com os adultos. Esta investigacao e o primeiro registro dos efeitos histopatologicos dos nano pesticidas. Palavras-chave: nano cloropirofos, nano imidaclopride, histopatologia, efeito de pesticida Rhynchophorus ferrugineus.
