Abstract
O uso de inseticidas tem se mantido como base do manejo de insetos herbívoros por mais de 70 anos, e é crescente a demanda por bioinseticidas na expectativa de que esses sejam uma alternativa sustentável eficiente no controle desses herbívoros. Entretanto, conhecer os efeitos de bioinseticidas sobre espécies polinizadoras das plantas cultivadas é fator essencial para que seja assegurado o serviço de polinização e principalmente a saúde das espécies. Este trabalho teve como objetivo avaliar o efeito dos bioinseticidas, extrato de Nim (Azadirachta indica) e DiPel (Bacillus thuringiensis) sobre as abelhas visitantes de flores de tomateiro. Realizou-se o plantio de mudas de tomateiro dos cultivares Pizzadoro e Santyno em três blocos. Cada bloco recebeu um tratamento: Nim, DiPel e testemunha. Foram coletados 111 indivíduos de abelhas, distribuídos entre sete espécies: Trigona spinipes, Apis mellifera, Exomalopsissp., Bombus morio, Augochloropsisspp. Os resultados sugerem que os bioinseticidas não exercem efeito repelente ou letal sobre as abelhas e possivelmente o extrato de Nimfuncione como atrativo para esses polinizadores.
The use of insecticides has remained the mainstay of herbivorous arthropod management for more than 70 years and is growing up the demand by bioinsecticides expecting that this will be a sustainably alternative top pest control. Knowing the effects of bioinsecticides on pollinating species is an essential factor in ensuring the pollination service and especially the health of the species. This work had as objective to evaluate the effect of the bioinsecticides, Nim extract (Azadirachta indica)and DiPel (Bacillus thuringiensis) on the bees visitors of flowers of tomato. Planting of tomatoes of the Pizzadoro and Santyno cultivars was carried out in three blocks. Each block received a treatment; Nim, DiPeland control. A total of 111bees were collected, distributed among seven species: Trigona spinipes, Apis mellifera, Exomalopsis sp, Bombus morio, Augochloropsis spp. The result suggests that the bioinsecticides does not exerce repelent or letal effect on bees and that the Nim extract possible exerts an attractive function for pollinators.
