Mexican strain of PNC has implications for IPM programs

摘要

As all producers across the pecan belt know, where the pecan nut case-bearer, Acrobasis nuxvorella Neun-zig, (Lepidoptera: Pyralidae) is present, it is considered one of, if not the most important nut-feeding insect of pecan. In Texas, management of this insect is considered the cornerstone of the pecan IPM program. Successful management of PNC is based on monitoring emergence of first-generation adults, monitoring oviposition and applying an insecticide on an as-needed basis. In 1996 producers had available to them a monitoring tool for detecting emerging adults which used the recently discovered sex pheromone that females use to call males. The use of this pheromone in conjunction with a sticky trap has been used successfully in Texas, New Mexicoand Oklahoma to monitor adult activity.
