Technical Abstract: Primary reliance on synthetic insecticides for control of diamondback moth has usually failed because of insecticide resistance and/or reduction of natural enemies by insecticides. Insecticide resistance has also been more recently documented with biological insecticides such as Bacillus thuringiensis and some growth regulators. Insecticide resistance management tprograms must be implemented and new alternative management strategies mus be developed. Our laboratory has documented high levels of resistance to the major insecticides, including Bacillus thuringiensis subsp. kurstaki, used against diamondback moth and proposed discriminating doses to assess potential field performance. Additionally, we have tested resistance management strategies for use of Bacillus thuringiensis when applied as a foliar spray and when incorporated into plants. Such strategies include both refuge size and placement. In laboratory, greenhouse and field studies swe have promising results for managing diamondback moth using foliar spray of a commercial formulation of Beauveria bassiana. However, we have had less promising results controlling diamondback moth through the presently available technology for mating disruption using pheromones.
