Abstract

Larvae of H. armigera successfully develop on tobacco plants, especially on their generative organs, where they cause serious damages on tobacco seed. Beside tobacco, they also attack cotton, corn, peppers, tomato, soybean and other cultivated plants. In 2005, the percentage of tobacco stalks attacked by H. armigera ranged from 24% in middle plots, where tobacco was in the stage of flowering, to 38% in margin plots, where stalks had formed seed capsules. During their life cycle, larvae of H. armigera are subjected to various diseases, parasites and predators. Mortality of larvae in natural conditions averages 30.41%. The highest efficacy in the control of this pest were obtained with the insecticide Metomyl 90 SP, with 90% mortality.
