摘要
Kairomones for Trichogramma spp. were evaluated in the field on soybeans and crimson clover. Blanket (complete coverage) spraying of plots (either a synthetic tricosane or an eluate from a hexane extract of moth scales, depending on the responsiveness of the Trichogramma spp. present) resulted in increased parasitization by released and wild Trichogramma populations. The increased parasitization resulted for both natural and artificially applied eggs.
