Abstract: Trabala vishnou gigantina is a defoliator moth of the Lasiocampidae family (Lepidoptera). The eclosion, mating, oviposition and life span of the Trabala vishnou gigantina adults were investigated in the laboratory at 24±1 and 50±10% rh under 12L:12D. The results showed that emergence activity of T. vishnou gigantina occurred throughout the day, 71.45% of females and 67.68% of males emerged at night. Males emerged significantly earlier than females. The highest emergence frequency occurred at 1900-2200 h. The highest mating frequency occurred between 300-400 h for 2 days old moths and then decreased gradually. Females normally copulated only once in their whole life spans with several times for males. For most adults, the duration of mating was 14~16 h.
