Abstract

The diel oviposition patterns of Anopheles albimanus and An. freeborni derived from Panama and California, U.S.A., respectively, were studied in the laboratory by recording the egg-laying of individuals and colonies at 2-h intervals. Anopheles freeborni oviposition patterns were almost exclusively nocturnal, with 80% of eggs being laid during the scotophase. A large, well-defined peak of oviposition, comprising about 70% of eggs laid, occurred 4-6 h before sunrise. Anopheles albimanus oviposition patterns were bimodal with crepuscular and nocturnal components, 68% of eggs being laid shortly before lights went 'off' or 'on' and 32% during the scotophase. A small, well-defined peak of oviposition, comprising about 42% of eggs laid, occurred immediately following lights off (i.e. 18.00-20.00 hours). Nulliparous females allowed to engorge on human blood matured, on average, 104 follicles (range 80-142) for An. albimanus and 114 follicles (range 31-201) for An. freeborni.
