The maximum consumption of the larvae of the pest and vector mosquito Culex quinquefasciatus by the predatory mosquito Culex (Lutzia) raptor was studied at various instars of both the predator and the prey. The prey preferences of the predator when given lavae of different instars were also investigated. The IVth instar of the predator consumed the maximum number of Ist instar and the maximum biomass of IVth instar larvae of the prey. Instars I and II of the predator preferred the Ist of the prey; instars III and IV of the predator preferred instars II and III of the prey respectively. The predator consumed an average of 157.1 larvae during its whole larval period, when each instar of the predator was given its preferred instar of the prey.
研究了捕食性蚊虫致倦库蚊（Culex (Lutzia) raptor）在捕食有害媒介蚊虫致倦库蚊（Culex quinquefasciatus）幼虫时，在捕食者和猎物的不同龄期的最大食量。还研究了捕食者在面对不同龄期幼虫时的猎物偏好。捕食者的四龄幼虫消耗猎物一龄幼虫的数量最多，消耗猎物四龄幼虫的生物量最大。捕食者的一龄和二龄幼虫偏好猎物的一龄幼虫；捕食者的三龄和四龄幼虫分别偏好猎物的二龄和三龄幼虫。当给捕食者的每个龄期提供其偏好的猎物龄期时，捕食者在整个幼虫期平均消耗157.1只幼虫。
