Abstract
A laboratory study (27 C-30 C) on the suitability of tropical fruits for the larval developm ent shows that it is in the order o f : Papaya carambola banana mango water-melon jackfruit citrus pineapple. In a suitable host i.e. papaya the weight of the pupa was 11.6 g and life-cycle was 20.4 days. In the least suitable host i.e. pineapple the weight of pupa was 4.9 g and life-cycle was 1 7.4 days. With papaya as food the life-cycle o f D. dorsalis depended on the density of the larvae within the food. A density o f 10 larvae in 20 g of food had a life-cycle o f 21. 7 days whereas a density o f 50 larvae in the same quantity o f food had a life-cycle o f 15.1 days. The percentage of adult emergence decreased with increase in the larval density.
