Efficacy of bifenthrin in reducing the risk of ambrosia beetle infestation in pecan

Ambrosia beetles are small, fungus-farming beetles that infest number of woody ornamentals and horticultural crops, including pecan. However, practical information regarding the effective management of this pest is limited. Field experiments were conducted to determine the efficacy of bifenthrin in reducing the attack of ambrosia beetles by evaluating its application rate, frequency, and residual longevity. Our study suggests that the application of bifenthrin at 50% of the labeled rate and 14-day interval could successfully reduce ambrosia beetle attacks. We will discuss these results in the context of establishing a practical management approach for ambrosia beetles in pecan production.
