STUDIES OF THE ECOLOGY OF CLARK AB, CENTRAL LUZON, R. P. II. A COMPREHENSIVE MOSQUITO SURVEY.
Abstract
Approximately 60 - 65 species of mosquitoes are present on Clark AB in any given year. However, there are marked changes from year to year in the composition of this group of species, probably as a result of variations in rainfall. Because of climatic variation from year to year, surveys should last at least five years. Investigation of the relationship between chance and microclimatology in discontinuous breeding and resting areas should be pursued. Some factor other than chance appears to be involved. There is both a practical and theoretical necessity for using a broad range of collection methods in a survey. Even though a species is zoophilic, very large populations may pose a threat to man because the small fraction that bites man may be large numerically. C. tritaeniorhynchus summorosus is the most important species of mosquito on Clark AB. Satisfactory methods for pooling mosquitoes for virus isolation have been developed using a power aspirator for collection and a carbon dioxide stage for sorting.
