title: [Impact of starvation on predation by male adult Chrysopa septempunctata].
abstract: The predation on Schizaphis graminum by male adult Chrysopa septempunctatata at various levels of starvation was examined in this paper. Th results showed that the functional reactive types of predator were not altered by its starvation duration, and the amount(Na) of catched S. graminum by C. septempunctata within 24 hrs varied with duration time(t), which could be expressed by the model: Na = 100/(1 + e-0.3088 - 0.0996t). The relationship between predation rate(v) and time(x) could be described as v = 6.7117 x-0.7928. The male adult predators preferred feeding on the young preys.
