Tips on thrips: Management in the greenhouse

摘要

One of the most predictable and chronic pests of greenhouse crops is the western flower thrip.This thrip species is the main pest found in greenhouses and has been particularly problematic since its introduction to Canada in the 1990s. Factors leading to the establishment of thrips in greenhouse crops include its short generation time, ability to disperse rapidly, resistance to pesticides and production of male offspring without mating. Also contributing to the destructive potential of thrips, as well as that of all other greenhouse pests, is the practice of year-round cropping.
