Agricultural Zoology Department, Faculty of Agriculture, Cairo University, Giza, Egypt aut Effect of prey density on predaceous efficiency and oviposition of Agistemus exsertus (Acari: Stigmaeidae) [Elektronische Daten] [M. Nawar] The oviposition and prey consumption rates ofAgistemus exsertus Gonzalez depend on the number of prey available to the predator. The number of eggs laid by the predator female and the consumption ofTetranychus urticae Koch as prey increased with increasing prey density to maximum averages of 2.3 deposited eggs and 5.8 devoured larvae per day at a prey density of 7 larvae. Higher levels of prey decreased predator oviposition and feeding capacity.
