摘要：

The lacewing Chrysopa cognate, one of the principal predators of aphids in Korea, was tested for responses to the aphid sex pheromone components (4aS,7S,7aR)-nepetalactone and (1R,4aS,7S,7aR)-neperalactol and the aphid alarm pheromone (E)-beta-farnesene. Electroantennogram responses were obtained to the sex pheromone components but not to (E)-beta-famesene. The sex pheromone components were attractive in a Y-tube olfactometer assay and in field trials with water traps, but no attraction was observed to (E)-beta-farnesene.
