Life History and Habits: Biology as recorded in State of Madras, southern India, is as follows: Preoviposition period lasts approximately 4 days. Eggs are deposited in a hole made in the fruit by the female, often near the stalk. As many as 8 eggs are deposited in each hole. Generally, however, one hole contains 3-4 eggs. When more than 10-12 eggs are deposited in a single fruit, larvae do not obtain sufficient nourishment and subsequent pupae and adults are undersized. Mature larvae drop to the ground, either in shriveled skins of infested fruits or before these fall. Larvae leave infested fruits and enter the soil for pupa- tion, the depth varying from to 2 inches. Adults emerge between 8 and 10 Infested fruits are first ridged by brown, dried liquid over the ovi- position puncture. After 2 days, a hollow develops at the point of oviposition and the surrounding tissues become soft and brown; after 4-5 days, the whole fruit becomes discolored, unless it contains only a few larvae, and falls. Under laboratory conditions,in September and October, when the mean shade temperature was ° F. and the relative humidity percent, the egg, larval and pupal stages lasted 2-4, 4-6 and 8-10 days, respectively. Development period lasts 15-17 days, and there are 6 generations a year.
