Monitoring of male adults of the Comstock mealybug Pseudococcus comstocki by using sex pheromone traps in a commercial grape greenhouse in Osaka Prefecture

Abstract

Seasonal occurrence of male adults of the Comstock mealybug Pseudococcus comstocki was investigated using sex pheromone traps for four years in a commercial grape greenhouse in Osaka Prefecture. The first peak of the number of male adults captured on the traps was found in late March, with the second peak from late April to early May and the third peak from mid-June to early July. Thus, the sex pheromone trap for the mealybug could detect the peaks in the number of male adult in the grape greenhouse.
