SEASONAL ABUNDANCE AND PARITY RATES OF ANOPHELES SPECIES IN SOUTHERN THAILAND

Mosquitoes were collected with human bait, animal bait, and CO2-baited light traps during a 13-month period in 5 villages located along the Myanmar border in southern Thailand. Altogether, 11,608 adult females consisting of 21 anopheline species were collected. Abundance of speci es varied according to the village where collections were made. In one village that was studied most intensely, Anopheles minimus was the mo st commonly collected species, representing 55.6, 10.6, and 56.5% of t he human bait, cattle bait, and light trap collections, respectively.
