FEEDING PREFERENCE OF Spodoptera frugiperda (SMITH) (LEPIDOPTERA: NOCTUIDAE) ON Phaseolus vulgaris L. GENOTYPES

摘要

The species Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is a widely distributed pest in the American continent and with a polyphagous habit, causing damage to several crops of economic importance, such as bean bean (CASMUZ et al., 2010). The most control measure to manage S. frugiperda is based on sprayings of chemical insecticides. However, alternative methods less damaging to the environment have been proposed. The host plant resistance is one of them, through plants that present in their constitution genes that are capable of producing substances that interfere in the behavior and/or development of the insect (BOICA JUNIOR et al., 2015). The ability of these plants to tolerate damage caused by insect pests has been aided in breeding programs to obtain genotypes with resistance characteristics. Thus, the aim of this study was to evaluate S. frugiperda larval feeding preference in common bean genotypes.
