Abstract

Male and female Tenagogottus fluviorum (Fabricius) were exposed to different size classes (I, II, III, IV and pupa) and different densities (25, 50, 75, 100, 125) of Culex quinquefasciatus larvae as prey. Predatory efficiency of the female bug is higher than that of male. However, both the sexes of the predator prefer large sized prey. The size in predatory performance of the bug is directly proportional to the increase in prey density. Attack rate and handling time as two statistical constants were derived from the prey death rate caused by the predator and their significance is discussed.
