摘要： The geometrid, Ectropis grisescens Warren, is one of the most serious defoliators of the green tea, Camellia sinensis. In the present study, adult emergence, calling behavior, mating activities, and oviposition patterns were observed and the effect of female sex pheromone was evaluated under laboratory conditions (25 +/- 1 degrees C, 14:10 light/dark and 70-75% RH). Adult emergence and calling behavior occurred only at the scotophase. The peak emergence occurred 2 h into the scotophase for males and 3 h for females. Female calling behavior occurred during 1-4 days after eclosion, with most callings among the 1-day-old and the calling gradually decreasing by the age. Mating behavior was first observed at the 2 h into the scotophase. While the mating peak time was similar, 6-8 h into the scotophase for single-pair and multiple-pair groups, the peak of oviposition was 3 days after mating. The pheromone gland extracts from the abdominal tips of 1-2 days virgin female moths were more attractive than the virgin females or the control in the wind tunnel tests. Our findings provide scientific basis to ecological control of E. grisescens.
