Effective, economical, and efficient long term management of both onion thrips and onion maggot continues to be a challenge in the production of dry bulb onion. Both insects pests continue to be a high pest priority for Wisconsin onion growers. Problematic populations of onion thrips are not regularly the result of warm summer time temperatures combined with insensitivity to the standard insecticides. Furthermore, many of the currently registered products for control of onion maggot are not equally effective against the seed corn maggot which is becoming locally abundant. As a result, thrips and seed maggot management is a top priority and an improved understanding of the ecology and management of these pests is essential towards the development of long-term control methods.
