Integrated Pest Management (IPM) in Greenhouses

摘要

"Integrated Pest Management (IPM) in Greenhouses" was the topic of a fact-filled presentation by Dr. R. Chris Williamson at the Wisconsin Fresh Fruit and Vegetable Conference, held earlier this year in Stevens Point, Wis. Williamson is with the Department of Entomology, University ofWisconsin. Greenhouse insects are difficult to manage, the speaker pointed out. Among the reasons are multiple generations (up to 20 per year), lack of natural enemies to reduce populations, almost unlimited food supply,constant environmental conditions, some life stages are not susceptible to treatment and growing major insecticide and miticide resistance.
