Abstract : During a mosquito survey of Clark Air Base, Pampanga, Luzon, Philippine Islands, a New Jersey type light trap was operated for a period of one year. Of the 16 genera and 244 species of mosquitoes reported from the Philippines, seven genera and 42 species were collected in the trap. Fifty-one percent of the mosquitoes collected were Culex species and 46 percent Anopheles species. The three most common Anopheles collected were A. subpictus indefinitus (Ludlow), A. vagus limosus King and A. peditaeniatus (Leicester). A. minimus flavirostris (Ludlow), a primary vector of malaria in the Philippines, was not collected in the light trap. Evening flight activities of mosquitoes showed that most were collected between 6-8 p.m. Culex tritaeniorhynchus summorosus, a probable vector of Japanese encephalitis virus in the Philippines, appeared to be most active between 6-7 p.m. The most mosquitoes per trap night were collected during March of the hot-dry season. This can be explained by the tremendous increase of Anopheles subpictus indefinitus during this period. With the exception of this one Anopheles the mosquito population was heaviest during the rainy season (July-Sept). Culicine populations peaked during September, the month of heaviest rainfall. Anopheline populations declined during that period. Lowest mosquito activity was in the months of January, February and May. (Author)
