Biological control against grapevine insect pests

Worldwide viticulture covers about 7.5 million ha and makes intensive use of pesticides The main insect pests threatening worldwide viticulture are currently two moth species. Scientists Thiery et al. critically reviewed the different options able to reduce or replace synthetic insecticide-based control. Very recent results promote the use of grassing and floral strips between the grape rows to increase pest control by spiders or parasitoid wasps. The production and release of such natural enemies have a great potential to render biological control strategies more efficient and reduce insecticide use in vineyards.
