Conteúdo: | The objective of this study was to evaluate the toxicity and preference (oviposition and emergence of adults) of Zabrotes subfasciatus (Coleoptera:Chrysomelidae: Bruchinae) in Phaseolus lunatus grains with commercial essential oils of Acorus calamus, Betula lenta, Cinnamomum cassia and Citrus aurantium. The contact, fumigation and preference tests were carried out to check the effect of essential oils on the insects. In the contact and fumigation test the lethal concentrations LC50 and LC95 were determined. In the contact test (A) calamus was the most toxic with toxicity ratio 61.17. It has been found in the regression analyzes that increased concentrations of essential oils reduced the number of eggs and insects emerged. In the fumigation test, (B) lenta was the most toxic with toxicity ratio 86.2. The concentrations 0.2; 0.6; 25; 1.2 &#956;L / 20 g of (A) calamus, (B) lenta, (C) aurantium and C. cassia provided a higher reduction of eggs and adult emergence in the preference test. The essential oils tested can be used in the control of Z. subfasciatus, resulting in mortality and reduction of oviposition and adults.
