| Objetivou-se avaliar o efeito de extratos aquosos de folhas de nim, Azadirachta indica, frutos de pimenta-malagueta, Capsicum frutescens, rama e folhas de melão-de-são-caetano, Mormodica charantia, sementes de pimenta-do-reino, Piper nigrum e NeenMax® (óleo de nim 2% i.a) para o manejo do pulgão, Lipaphis erysimi, em cultivo orgânico de Brassica oleracea. Aplicações dos extratos a 10% (v/v) foram realizadas semanalmente, durante cinco semanas. Avaliou-se o número de plantas infestadas, porcentagem de folhas infestadas e ocorrência inicial de infestação em diferentes dias após o plantio (DAP). Os tratamentos não causaram redução populacional significativa do pulgão L. erysimi sobre brócoli em sistema orgânico. |

| The effects of ethanolic and hexanic extracts of soursop and sugar apple (EES, EHS, EESA and EHSA, respectively) on Aphis gossypii (Hemiptera: Aphididae) and its natural enemy Eriopis connexa (Coleoptera: Coccinellidae) by contact exposure, residual effect and ingestion tests were evaluated. The estimated LC50 and LC99 values for A. gossypii were 0.39% and 5.47% for (EESA); 0.23% and 1.19% for (EES); 0.47% and 4.39% for (EHSA); and 0.42% and 6.38% for (EHS), respectively. Considering contact exposure, EES at 0.23% was innocuous, and EHS at 0.42% was slightly harmful; for adult ladybugs, only EESA (5.47%) was classified as slightly harmful, with the other treatments classified as harmless. The results were similar for the residual effect. For selectivity... |
