Eggs, larvae, and pupae of Helicoverpa mothsthe main insect pests of cottonare all attacked by many beneficial insects and research can be conducted in identifying critical habitats, resources needed to maintain them, and ways of encouraging their activity Lawrence They did so through the support of a few pioneering farmers, a handful of courageous and dedicated researchers and a work ethic of freedom of interaction, cooperation and devotion to finding safe, economical and effective alternative biological solutions to pest problems in agriculture and throughout the environment.

Adults have a dot on each wing and are quite waxy. For example, the Lymantria dispar multicapsid nuclear polyhedrosis virus has been used to spray large areas of forest in North America where larvae of the gypsy moth are causing serious defoliation.

If an insecticide is needed, every effort should be made to use a selective material in a selective manner. IPM focuses on long-term prevention of pests or their damage by managing the ecosystem With IPM, you take actions to keep pests from becoming a problem, such as by growing a healthy crop that can withstand pest attacks, using disease-resistant plants, or caulking cracks to keep insects or rodents from entering a building.

Other than the initial costs of collection, importation, and rearing, little expense is incurred. Relatively few natural enemies may be released at a critical time of the season inoculative release or literally millions may be released inundative release.
