Alternative Products On Coffee Leaf Miner Oviposition

Summary in the original language of the document

This study, aimed to evaluate the influence of alternative products on the oviposition of Leucoptera coffeella. The tests were performed in a lab on seedlings of coffee IAPAR-59 which were eight months of age and had at least four pairs of leaves. The treatments were: control without application, distilled water, propolis extract, lime sulphur, silicate clay, neem oil, pyroligneous extract with pepper and garlic, kaolin, and kaolin + neem oil. The treatments were sprayed with a pressure of 2 bar. We evaluated the effect of pesticides on L. coffeella oviposition on treated leaves. The evaluation results of the test oviposition leaf miner no choice were subjected to analysis of variance, using the non-parametric Kruskal-Wallis test followed by Dunn’s test of multiple comparisons at 0.5 %. The propolis extract, neem oil, neem oil + kaolin, and pyroligneous extract with pepper and garlic repelled oviposition of L. coffeella. Thus, although still to be evaluated under field conditions, it is possible that the application of these products can reduce coffee plant colonization by L. coffeella, thus avoiding high pest populations.
