The conidia by the wind or contact with the spread of spread of insects, spores contact with parasites, in the appropriate conditions of temperature and humidity began to germinate and invade the worms, the body of a large number of growth and reproduction, causing pests and death. In the appropriate conditions, insect corpse grows a large number of spores in vitro, the spores of newborn by wind or contact with the spread of spread of parasites, against healthy worms.
