Two new tactics for controlling southern pine beetle infestations use a bee
tle-produced inhibitor: verbenone. The techniques, verbenone-only and verbe
none-plus-felling, reduce tree loss by disrupting infestation growth. In th
ree years of field tests, the verbenone-only tactic completely suppressed 6
9 percent of the treated infestations, and the verbenone-plus-felling tacti
c suppressed 86 percent. The tactics provide much-needed alternatives to cu
rrent control techniques and will allow suppression of infestations where t
ree felling is restricted or prohibited. In anticipation of registration of
the pheromone by the Environmental Protection Agency, a technology transfe
r program has been developed to provide the materials and training necessar
y for effective use of the treatments.
