Emamectin Benzoate was registered recently in Brazil to control Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae) in soybean. We studied the baseline susceptibility of Mato Grosso populations of C. includes to support Insect Resistance Management programs by standard feeding assays on insecticide-surface of artificial diet. Variation in susceptibility between populations was low. The LC50 values from 11 populations varied between 0.015 a 0.065 μg i.a. cm-2. Based on our results, we propose the discriminant concentration of 2.867 μg i.a. cm-2 of emamectin benzoate to monitor insecticide resistance in C. includes.

PR-BR: Cosmopolites sordidus (Germar, 1824) (Coleoptera: Curculionidae) e Metamasius hemipterus (Linnaeus, 1758) (Coleoptera: Curculionidae) são as principais coleobrocas associadas a cultura da bananeira no Brasil. Objetivou-se com este estudo avaliar o efeito de iscas atrativas para o monitoramento destes coleópteros, no período de maio a setembro de 2012 (estação seca) e outubro de 2012 a abril de 2013 (estação chuvosa), nas condições de bioma amazônico. O experimento foi instalado em um bananal comercial (cv. Nanicão), dividido em três parcelas de 0,5 hectare cada, avaliando os seguintes tratamentos: 1) feromônio sintético de agregação específico para a espécie C. sordidus (testemunha); 2) melaço de cana-de-açúcar e; 3) toletes de cana-de-açúcar. Verificou-se que as três iscas apresentaram comportamento similar no período seco e chuvoso, com maior captura de C. sordidus na época chuvosa. O melaço de cana-de-açúcar e os toletes de cana-de-açúcar não demonstraram eficiência na captura de C. sordidus. A isca atrativa confeccionada de toletes de cana-de-açúcar, em armadilha pitfall, mostrou-se eficiente para monitoramento e coleta massal de M. hemipterus em áreas de bananal. | EN: Cosmopolites sordidus (Germar, 1824) (Coleoptera: Curculionidae) and Metamasius hemipterus (Linnaeus, 1758) (Coleoptera: Curculionidae) are the main beetles associated with banana plants in Brazil. The objective of this study was to evaluate the effect of attractive traps for monitoring these beetles, from May to September 2012 (hot season) and October 2012 to April 2013 (rainy season), in the Amazon biome conditions. The experiment was installed in commercial banana plantations that produce the banana variety cv. Nanicão, divided into three plots of 0.5 hectare each, assessing the following treatments: 1) synthetic aggregation pheromone for the species C. sordidus (control); 2) molasses sugarcane and; 3) sugarcane oarlock. It was found that the three baits showed similar behavior in the hot and rainy season, with the highest catch of C. sordidus in the rainy season. The molasses sugarcane and sugarcane oarlock did not show efficiency in the capture of C. sordidus. Attractive bait sugarcane oarlock, in pitfall trap, proved efficient for both monitoring and mass collect M. hemipterus in banana plantations. Made available in DSpace on 2018-11-04T00:31:02Z (GMT).
