The defensive behavior of colonies of Vespula pensylvanica (Saussure) and Bomhus sonorus Say is assayed with an easily-constructed electronic monitor that counts the number of impacts of insects attacking Ping-Pong ball targets. Black targets are attacked, and white targets are not. The administration of smoke to colonies before disturbing them greatly reduces the number of attacks. In B. sonorus, the reduction was >2-fold and in V. pensylvanica >10-fold. This suggests mechanisms of the effect of smoke besides those that have been described for honey bees. This effect may be useful to subdue these insects during insecticide treatments to destroy their nests.
