Resumo: The effects of six pesticides applied to the coffee crop on eggs and their consequences on the subsequent developmental stages of Chrysoperla externa (Neuroptera: Chrysopidae) were evaluated under laboratory conditions. The pesticides and water (control) were sprayed on eggs using a Potter´s tower. After spraying, forty eggs per treatment were individualized in glass tubes and maintained in a climatic chamber, in order to evaluate immature development of this predator. The treatments showed significant differences for egg viability and survival of first-instar larvae. Chlorpyrifos, sulphur and copper oxichlorate reduced the treated egg viability, whereas both sulphur and betacyfluthrin reduced the survival of first-instar larvae. Endosulphan and azociclotin reduced the daily oviposition of this green lacewing species. The harmless products (Class 1, E < 30%), can be recommended for use in integrated pest management programs in coffee crops, in order to preserve this predator.

Los plaguicidas y el agua (control) fueron aplicados en los huevos usando una torre de Potter. Después de la aplicación, cuarenta huevos por tratamiento fueron individualizados en tubos de vidrio y mantenidos en cámara bioclimática, con el objetivo de verificar las posibles anormalidades en el desarrollo de este depredador. Los tratamientos mostraron diferencias significativas para la viabilidad de los huevos y la supervivencia del primer instar larval. Chlorpyrifos, azufre y oxicloruro de cobre redujeron la viabilidad de los huevos tratados, mientras que el azufre y el betacyfluthrin redujeron la supervivencia del primer instar larval. Endosulfán y azociclotin redujo la oviposición diaria de esta especie crisopa. Los productos inocuos (Clase 1, E < 30%), pueden recomendarse para su uso en programas integrados de manejo de plagas en los cultivos de café, a fin de preservar este depredador.Sociedad Colombiana de Entomología2017-08-10T16:51:16Z2017-08-10T16:51:16Z2012-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, R.
