Abstract : The population development, survival and fecundity of O. biharensis were studied on mango, litchi (Litchi chinensis) and longan (Dimocarpus longan) fruit crops. The developmental duration from egg to adult was the shortest (14.57 days) on longan, and the longest (20.71 days) on mango. The survival rate of O. biharensis on longan was the highest (93.8%), while on litchi was the lowest (83.8%). The fecundity of female adults on longan was the highest (46.63), while on mango was the lowest (7.32). The intrinsic rate of natural increase on longan was the highest (0.1328) while on mango was the lowest. The population trend index could be ranked from the highest to the lowest: longan > litchi > mango.
