Studies conducted during 1967 to 1969 revealed that contrary to earlier belief Amsacta moorei Bulter remained active from about the end of June to the middle of October. There were two distinct races: one comprising 25-30% of the population was univoltine while the other had three broods. Eggs hatched in four days during July-August and in six days during September. Larvae molted 4-6 times and became full-grown in 17-30 days. Pupal period was very variable. In case of univoltine race it was about 10.5 months, whereas in case of the multivoltine race, it was 6-35 days in the first two broods and about 9 months in the third brood. Studies on light trap collection revealed that maximum number of moths were attracted during June-July when diapausing pupae of both the races emerged as moths together. About five times more males were attracted to light than the females. [AS]
