PEST MANAGEMENT: MONITORING POPULATIONS OF ARCHIPS ARGYROSPILUS AND ARCHIPS ROSANUS (LEPIDOPTERA: TORTRICIDAE) WITH SEX PHEROMONE TRAPS

Abstract

AbstractThe sex pheromones of Archips argyrospilus (Walker) and Archips rosanus (L.) were field evaluated to determine if they could be used to monitor populations in orchards where pest management programs were applied. Traps baited with the sex pheromones of A. argyrospilus caught males which reflected population levels estimated by other sample methods. Traps baited with the sex pheromones of A. rosanus caught high numbers of males but the numbers did not correlate with other population estimates. A. rosanus has a wide host range, and trap data indicate that males were attracted from sources outside the monitored orchards. Results indicated that the sex pheromones of A. argyrospilus could be used to estimate populations but with A. rosanus further studies on trap placement are necessary to minimize male influx.
