Thrips Resources

Research on control of thrips has been ongoing for many years, based primarily on the use of insecticides. Thrips are so small that the untrained eye rarely sees them, but the damage is apparent on infested flowers. Proper rotation of insecticides is critical to successful control.

Thrips are known to develop resistance to insecticides very rapidly. Over the last 30+ years, thrips control measures have been successful, to some extent, due to the introduction of new classes of insecticides and research showing the proper rotation of pesticides and cultural practices affecting thrips.

Thrips are one of the most difficult insects for flower growers to control. For wholesale and retail florists, the damage from thrips renders flowers unmarketable.

The industry is seeing fewer and fewer new insecticide classes introduced to the market, so thrips seem to be developing greater resistance to existing insecticides. In the past, there have been researchers focusing on pesticide control and others concentrating on biological control measures. In most cases, research has not looked at how best to use insecticides in unison so that specific recommendations could be developed for the industry.
