摘要：

In 124 days of field tests, 88.7% of male, 87.3% of female, and 90.2% of 5th-instar Nezara viridula were caught on cages containing male N. viridula rather than on female or control cages. Likewise, 92% of the female and 86% of the male parasite, Trichopoda pennipes (F.), were caught on cages containing male N. viridula. Attraction of N. viridula occurs throughout the daylight hours, but is strongest in a 5-min period immediately prior to complete darkness. The data suggest the presence of a male-emitted aggregation pheromone in N. viridula, acting concomitantly as a kairomone for T. pennipes females.
