Abstract

Ectropis grisescens Warren is a severe defoliator species that seriously affects the quality and production of tea in China. In order to provide guidance for using sex pheromone of E. grisescens in the field, the effect of sex pheromone dispenser, trap type, height and interval were compared and determined. The results of field trials showed, isoprene septa dispenser was more suitable than silicone septa dispenser and PVC capillary tubing. Sticky wing trap was the most appropriate trap among five types of traps. Trap set 25βcm above tea plant, and 15βm between interval were determined as the best operational parameters to catch E. grisescens male moth. The results provided scientific basis to develop effective protocols for using the sex pheromone to attract and kill E. grisescens male moth.
