1. Bases ecológicas para o manejo de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em sistemas orgânicos de produção de tomate
The whitefly Bemisia tabaci biotype B stands out, among the diverse community of pest herbivores that colonize the tomato crop, due to the direct damages and transmission of several pathogenic viruses (Geminiviridae) causing productivity losses. The spraying of insecticides for its control selects resistant populations and promotes the dispersion of adults t

2. Coccinellidae (Coleoptera) usando plantas aromáticas como sítio de sobrevivência e reprodução em sistema agroecológico, e aspectos biológicos em condições de Laboratório / Coccinellidae (Coleoptera) using aromatic plants as survival and reproduction site in agroecological system, and biological aspects under laboratory conditions.
Among the natural enemies of agriculture pests, the Coccinellidae predators are detached. Some coccinellids only complete their development and produce viable eggs and progenies when they consume their preferred prey. However, when this prey is scarce or in presence of a prey of low quality, certain coccinellids feed on alternative food resources, such as ex

3. Responses of two ladybeetles to eight fungicides used in Florida citrus: Implications for biological control
Two ladybeetles, Cycloneda sanguinea and Harmonia axyridis, were exposed in the laboratory to eight fungicide formulations commonly used in citrus production in Florida. Both benomyl and the combination of copper and petroleum oil proved toxic to larvae of C. sanguinea that were exposed to concentrations corresponding to recommended field rates, either as le
