AVALIAÇÃO DE INSETICIDAS NO CONTROLE DE Aphis craccivora (HEMIPTERA: APHIDIDAE) EM FEIJÃO CAUPI (Vigna unguiculata)

Abstract

The black aphid, Aphis craccivora, is one of the main pests that affect cowpea, causing significant damage to production. One of the main strategies used in the control of this pest is the use of chemical insecticides, but the indiscriminate use of these products can be harmful to the environment and select resistant insect populations. Thinking the objective of this work was to evaluate the effectiveness of insecticides in the control of Aphis craccivora in cowpea. The experiment was conducted at the Biology Laboratory of the IF Goiano – Campus Posse, being used: T1 - Witness (application of distilled water); T2 - Neem oil; T3 - Isaria fumosorosea; T4 - Imidacloprid and T5 - Acetamiprid + Pyriproxyfen. Mean insect mortality and insect control efficiency were evaluated. synthetic insecticides and bioinsecticides. Synthetic chemical insecticides in mixture Acetamiprid + Pyriproxyfen and Imidacloprid showed the best performance, with 100% of control efficiency at 9 days after application (DAA). Despite having a slower effect, the natural insecticide based on nem was as efficient as the insecticides Imidachloroprid and Acetamiprid + Piriproxyfen for pest control. The microbiological bioinsecticide based on Isaria fumosorosea showed lower efficiency when compared to the others. The results are important and can help in the choice of products that help in the Integrated Management of Pests.
