Sobrevivência e capacidade de voo de Apis Melífera após exposição direta e oral ao Clorantraniliprole.

Abstract

The decline of Apis mellifera (Hymenoptera: Apidae) populations in agricultural areas is a worldwide concern, the uncontrolled use of insecticides is one of the main factors that harm both flight and death, thus hindering the pollination process. Therefore, this research’s objective was to evaluate the toxicity of chlorantraniliprole, widely used in Brazil, in the recommended commercial doses for different cultures, on the survival and flight capacity of adult workers of the Africanized bee A. mellifera. The work was carried out at the Laboratory of Entomology of the CCTA/UFCG, Campus Pombal/PB, and the levels of toxicity were evaluated through bioassays, corresponding to two forms of exposure: direct spraying on the bees and contaminated diet using five commercial doses, registered for pest control in several crops, in a completely randomized design consisting of 7 treatments, T1 - Absolute control - (distilled water); T2 - Positive Control (Thiamethoxam 0.30 g i.a. L-1); T3 Chlorantraniliproledose 1 (0.015 g i.a. L-1), T4 - dose 2 (0.05 g i.a. L-1), T5 - dose 3 (0.10 g i.a. L-1), T6 - dose 4 (0 .20 g i. a. L-1), T7 - dose 5 (0.30 g i. a. L-1), with each experimental unit formed by 10 adult bees. Doses were the same in both application methods (contaminated diet and direct spraying). The insecticide by the chemical group Antranilamide Chlorantraniliprole (Premio®), obtained low mortality rates on the A. mellifera bee, but affected the flight capacity at the maximum dose of (0.30 g i. a. L-1) in the direct spray method, being an alternative for pest control if used in the correct dosages. This research will help to better manage pests and preserve the A.mellifera bee.
