Pirate bug tag-team is double-trouble for thrips
The minute pirate bug, Orius insidiosus, was formerly thought to work alone, but now it appears this tiny agricultural ally of commercial growers and home gardeners may have a partner.
Greater numbers of growers are turning to biological control to combat pest problems. There are many different reasons for making the switch, but much of the interest has been driven by the increasing difficulties in controlling pests such as thrips with pesticides.
Aug. 13, 2009 — Ontario flower growers are boosting biocontrol research in the province. The board of directors of Flowers Canada (Ontario) recently presented a cheque for $50,000 to help fund thrip and whitefly research at the Vineland Research and Innovation Centre (VRIC).

Dec. 16, 2008, Beltsville, MD — The Agricultural Research Service (ARS) has granted an exclusive license to South Carolina Scientific, Inc., of Columbia, S.C., to produce and market an ARS-developed insect sex pheromone that can help control the pink hibiscus mealybug, a crop pest that can cause up $750 million in damage annually to U.S. crops.
The gall midge, Feltiella acarisuga, is a mosquito-like insect that can greatly assist in biological control of two-spotted spider mites (TSSM) in greenhouse vegetables.
Research is continuing to develop more effective controls and applications.

OVERTON – A new greenhouse largely funded by the Texas nursery plant industry will research ways to reduce chemical use and increase biological control of insect and other pests, said Texas AgriLife Extension Service experts.
They not only remove leaf material, but also reduce yield by feeding directly on fruits

Predatory mites can differ in their taste for different life stages of spider mites


Although it is wonderful to be able to choose from an array of predatory mites for biological control of the two-spotted spider mite, such choice has also made life more complicated. We need to gain as much information as possible about the various species when choosing the species of predator to release, and in determining the timing of release.
Study looked at number of eggs laid daily and total number of prey or eggs killed


Which are most effective in controlling two-spotted spider mites?

Greater success has resulted in growers developing more confidence in its use.
