Abstract
The present experiment was designed to learn the mortality (response per predator) of Hyphantria cunea and Podisus maculiventris, both reared in different ratios of densities in net cage. 1. Podisus maculiventris attacked about 94.6, 91.4 and 62.4% of the hosts at the ratio of densities, 200:10, 400:10 and 800:10 in each net cage in the lst generation. 2. Podisus maculiventris attacked about 96.3, 93.6 and 67% of the hosts at the ratio of densities, 200:10, 400:10 and 800:10 in each net cage in the 2nd generation. 3. About 98.7 and 98.4% of the hosts were pupated in the 1st and 2nd generations in the controlled group.
