Biting activity of mosquitos (Diptera: Culicidae) at a malarious site in Palawan, Republic of The Philippines.

Fifty-one species of mosquitos were collected at a malarious site in western Palawan, Philippines. Anopheles flavirostris, which is the primary malaria vector, was mildly exophagic and zoophilic, and had a peak biting activity from 0030-0130 hours. An. balabacensis, a secondary vector, was endophagic, anthropophilic, and was primarily active between 2000-0030. Of the 3 main genera, Culex were the most zoophilic, Aedes were the most anthropophilic, and Anopheles had species in both extremes. An. annularis, Ae. vexans, and Cx. vishnui showed similar biting activity patterns during both the rainy or dry seasons.
