The maximum consumption of the larvae of the pest and vector mosquito Culex quinquefasciatus by the predatory mosquito C. raptor was studied at various instars of both the predator and the prey. The prey preferences of the predator when given larvae of different instars were also investigated. The 4th instar of the predator consumed the maximum number of 1st instars and the maximum biomass of 4th-instar larvae of the prey. 1st and 2nd instars of the predator preferred the 1st instar of the prey; 3rd and 4th instars of the predator preferred 2nd and 3rd instars 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.
