Caracterização e avaliação de acilaçúcar sintético no comportamento da mosca-branca Bemisia Tabaci (Gennadius, 1886) biótipo B (Hemiptera: Aleyrodidae) em tomateiro

Abstract

Tomato plant growing is an important activity in Brazil both in production and in consumption, and the states of Goiás, São Paulo and Minas Gerais are the main producing states. In order to develop new products with insecticide activity, this work was developed with the aim synthesizing acylsugar, alelochemical present in the leaves that give natural resistance to the tomato plant Lycopersicon pennellii evaluating and its effects on the behavior of the whitefly. The layout used was a completely randomized design, with five treatments and five repetitions. The trials consisted of the following treatments: Santa Clara tomato plants cultivar sprayed with pure water (control); Santa Clara tomato plants cultivar sprayed with acylsugar 01 (synthesized starting from sucrose); Santa Clara plants of tomato cultivar sprayed with acylsugar 02 (synthesized starting from the glucose with chloride of zinc as catalyst); tomato plants Santa Clara cultivar sprayed with acylsugar 03 (synthesized starting from the glucose with acetate of sodium as catalyst) and tomato plants Lycopersicon pennellii splayed with pure water. The concentration of the composition used was of 0.05%. The results showed that the acylsugar 03 reduce the egg laying activity of the whitefly in the tomato plant. However, it seems necessary to deepen studies to evaluate the action of this product on the whitefly behavior.
