Summary: | Looking for alternatives to pesticides for Hypothenemus hampei control, the objective of this study was to evaluate the potential of aqueous and ethanolic plant extracts of Moringa oleifera (Moringa) and Tephrosia purpurea (tephrosia) (seeds, leaves and roots) and Melia azedarach (cinnamon), Nerium oleander (oleander) and Azadirachta indica (neem) (leaves only), on mortality and repellency of H. hampei and its compatibility with Beauveria bassiana, an important natural enemy of this pest. To assess the mortality, coffee leaves (Coffea arabica L) were treated by immersion in a solution of endosulfan and plant extracts at a concentration of 10% and then offered to adults of H. hampei. The repellency was evaluated in multiple-choice tests and in no-choice tests among coffee fruit treated and untreated The compatibility between extracts and Beauveria bassiana (CG 452) was analyzed by quantifying germination, colony forming units, growth and yield / productivity of conidia. The highest mortalities were observed when leaves were treated with ethanolic extract of T. purpurea (leaves) which did not differ from endosulfan, and aqueous and ethanolic extracts from M. oleifera seeds . In free-choice tests, all the ethanolic extracts showed repellent action, being higher for M. oleifera (root) and T. purpurea (seed). The aqueous extracts of M. oleifera (leaves and seeds) and N. oleander (leaves) showed the highest repellency. In no-choice tests the highest repellency level was for coffee fruits treated with A. indica (leaves). The ethanolic extract of M. oleifera leaves negatively affected B. bassiana germination. These studies showed the potential of these plant extracts for use in the field as an alternative to chemical control, once they are also selective for B. bassiana. |

Para avaliar a mortalidade, ofereceram-se aos adultos, folhas de cafeeiro (Coffea arabica L) tratadas por imersão em solução de endosulfan e em extratos vegetais na concentração de 10%. A repelência foi avaliada em testes com e sem chance de escolha, entre frutos de cafeeiro tratados e não tratados. A compatibilidade entre os extratos e Beauveria bassiana (CG 452) foi analisada quantificando a germinação, unidades formadoras de colônias, crescimento vegetativo e produção/produtividade de conídios. As maiores mortalidades foram observadas quando folhas foram tratadas com o extrato etanólico das de T. purpurea (folhas) que não diferiu do endosulfan, e de extrato aquoso e etanólico da semente de M. oleifera. Em testes com chance de escolha, todos os extratos etanólicos possuíram ação repelente, sendo que a maior repelência foi causada por M. oleifera (raiz) e T. purpurea (semente). Os extratos aquosos de folhas e semente de M. oleifera e de folhas de N. oleander apresentaram a maior repelência. Nos ensaios sem chance de escolha o maior nível de repelência foi para frutos de cafeeiro tratados com A. indica (folhas). O extrato etanólico de folhas de M. oleifera afetou negativamente a germinação. Estes estudos mostraram o potencial desses extratos para uso a campo como uma alternativa ao controle químico, sendo também seletivos para B. bassiana.UEL2012-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/896710.5433/1679-0359.2012v33n6Supl1p2849Semina: Ciências Agrárias; Vol. 33 No. 6Supl1 (2012); 2849-2862Semina: Ciências Agrárias; v. 33 n. 6Supl1 (2012); 2849-28621679-03591676-546Xreponame:Semina.
