Abstract

During a 13-month study on the ecology of malaria vectors in five villages in southern Thailand, specimens collected on human-bait, bovid-bait, and in light traps were tested for the presence of and circumsporozoite antigen by enzyme-linked immunosorbent assay. antigen was detected in seven specimens and in 21 specimens, together representing 0.4% of the 7,938 specimens tested. In one village, Palao-U, circumsporozoite antigen was detected in 16 (0.7%) of the 2,196 specimens tested. In this village, combined rates of infection with and were 0.6% for , 1.1% for , and 1.5% for . Circumsporozoite antigen was also detected in group, and group specimens. Combined and entomologic inoculation rates in the wet season (March–October) were 0.05 for , and , but 0 for . Rates were higher in the dry season (November–February): 0.26 for , 0.13 for , 0.13 for , and 0 for . The vectorial capacity, calculated based on human biting rate and rate of survival, of during the dry season was more than two-fold higher than that of , the species with the second highest vectorial capacity.
