Preservation and Augmentation of Insect Predators of the Western Pine Beetle
Abstract:Suggestions are given for preserving insect predators of the western pine beetle during chemical control operations. These include (a) leaving the basal section of the tree untreated and (b) avoiding spray deposits on the duff and litter surrounding the stump. The possibility of augmenting field populations of insect predators is discussed. The principal predator, Enoclerus lecontei, adapts well to laboratory conditions and produces large quantities of eggs. The egg and adult stages seem best adapted for release into the field.
