Research Advances on Bio-control of Greenhouse Insect Pests with Natural Enemies

In recent years,greenhouse area in the world increased greatly,and the pests in greenhouse occurred seriously.With environmental awareness and the need of pollution-free products of the public,the use of natural enemies in greenhouse has caught attentions of many researchers and farmers.The use of natural enemies of greenhouse insect including parasitoids and predators in the greenhouses were reviewed.The limiting factors in the use of natural enemies and the method of manipulation to enhance the biological control were menioned.The future research directions were also discussed.
