Tobacco bollworm H. armigera Hbn. is a polifagous pest, well adapted to adverse conditions.
Larvae successfully develop on tobacco plants, especially on their generative organs, where they cause serious damages on tobacco seed. As migratory noctuid, beside tobacco it also attacks cotton, corn, peppers, tomato, soybean and other cultivated plants.
In 2005/2006, the percentage of tobacco stalks attacked by H. armigera ranged from 24% to 30% in middle plots, where tobacco was in the stage of flowering, and from 38% to 44% in margin plots, where stalks had formed seed capsules.
During their life cycle, larvae of H. armigera are attacked by various diseases, parasites and predators. Mortality of larvae in natural conditions averages 30.41% and 33.63% in 2005 and 2006, respecively.
The highest efficacy in the control of this pest was obtained with the insecticide Metomyl 90 SP, with 90% mortality in 2005 and 100.00% in 2006.
