Abstract
Newly-emerged adults, having lived in the soil for 5-13 days, appeared on the ground and started to feed on host plant leaves in the laboratory. Females began to deposit their eggs in the soil 3-5 days after the feeding. In the test of June-July 1980, there was considerable variation in the oviposition period ranging from 2 to 71, 45 eggs on an average. The daily oviposition was intermittent indicating a fluctuation in the daily oviposition pattern. Mated females showed an alternation of active feeding and oviposition at a constant temperature of 25°C, whereas unmated females consumed a lesser amount of host plant leaves though they took much food in the first few days after feeding began.
