Abstract

A program to control was initiated in 1968 at the onset of an outbreak of dengue hemorrhagic fever on the island of Koh Samui in the Gulf of Thailand. About 90% of the domestic-water containers on the island, the principal source of breeding, were treated with the organophosphate Abate® (0,0,0′,0′-tetramethyl-0-0′-thiodi--phenylene phosphorothioate), and ground-applied malathion fogs were dispersed to kill adult mosquitoes in all the villages on Koh Samui. An island-wide reduction in both the larval and adult populations of was observed after this program. The duration of pronounced suppression varied from 2 to 8 weeks, according to area under surveillance and the monitoring techniques used. The Abate treatments were also effective in controlling the breeding of in artificial containers inside and around houses, and adults were temporarily suppressed in those areas where malathion fogs were applied. The control measures, however, had little apparent effect upon the populations outside the villages. There was no indication that the temporary reduction in the population on Koh Samui resulted in any significant invasion of domestic habitats of that species by .
