Resumo: Herbicides and plant growth regulators are often used in sugarcane management. However, the use of non-selective pesticides can cause adverse effects on the efficiency of beneficial insects in integrated pest management. Within this context, this study aimed to evaluate the effect of such products on the immature stages of the parasitoid Trichogramma galloi. Eggs of Diatraea saccharalis containing the parasitoid at the egg-larva stage and at the prepupal and pupal stages were immersed in test solutions of the following pesticides (maximum recommended doses for sugarcane): herbicides clomazone and diuron + hexazinone, and plant growth regulators trinexapac-ethyl and sulfometuron-methyl. The biological properties evaluated were emergence (F1 and F2) and number of eggs parasitized by T. galloi (F1). The products were classified according to percentage of reduction in emergence and parasitism: harmless (<30%), slightly harmful (30-79%), moderately harmful (80-99%) and harmful (>99%). The pesticides evaluated were considered to be harmless or slightly harmful to immature T. galloi and, thus, their use should be preferred for preserving this parasitoid species in sugarcane management programs.

Entretanto, o uso de compostos não seletivos pode prejudicar a eficiência de insetos benéficos no manejo integrado de pragas. Nesse contexto, avaliou-se o efeito desses produtos sobre as fases imaturas do parasitoide Trichogramma galloi. Ovos de Diatraea saccharalis contendo o parasitoide no período de ovo-larva e nas fases de pré-pupa e pupa foram imersos em caldas dos produtos avaliados (doses máximas recomendadas para a cana-de-açúcar), sendo eles: os herbicidas clomazone e diuron+hexazinone e os reguladores de crescimento de plantas sulfometuron-methyl e trinexapac-ethyl. As características biológicas avaliadas foram a emergência (gerações F1 e F2) e o número de ovos parasitados por T. galloi (F1). Os produtos foram classificados, conforme percentual de redução da emergência e parasitismo, em: inócuo (<30%), levemente prejudicial (30 a 79%), moderadamente prejudicial (80 a 99%) e prejudicial (>99%). Os compostos avaliados foram classificados como inócuos ou levemente prejudiciais aos imaturos de T. galloi e, por isso, devem ser preferidos, visando à preservação dessa espécie de parasitoide em programas de manejo da cana-de-açúcar.Sociedade Brasileira da Ciência das Plantas Daninhas2019-11-28T18:53:14Z2019-11-28T18:53:14Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfOLIVEIRA, H.
