| Sumario: | Attack behavior of the predator Podisus rostralis (Stäl) (Heteroptera: Pentatomidae) adults on fourth instar Bombyx mori L. (Lepidoptera: Bombycidae) caterpillars was studied in laboratory conditions. Ten 24 hours old adults of this predator were observed during two hours with the following attack behavior: (1) Predator: prey finding; prey observation; touching prey with antenna; attack behavior; prey paralysis; predator retreat after attack; attack cessation; successive attacks; and (2) Prey: defense. The predator P. rostralis found its prey before attacking and it approached it with slow circular movements. The attack was usually made in the posterior part of the prey to reduce defense reaction. Larger size of prey in relation to the predator resulted difficult prey paralysis but it occurred in less than two hours. |
