Abstract:
:Toxorhynchites brevipalpis, a predator on larvae of Aedes aegypti and other mosquitos, was successfully colonized in the laboratory. At 25 degrees C, embryonic development was completed within 50 hours of oviposition, while larval and pupal development together took a further 27-41 days. The adult mosquitos mated in cages as small as 15x15x15 cm, and the embryonated eggs were obtained 6-31 days after the adults emerged.
