"DMR-larval trap" for possible control of Aedes aegypti (L), the pricipal vector of DHF in Yangon

ABSTRACT

The Department of Medical Research (DMR) has developed a larval/pupal trap with a view to control Aedes (Stegomyia) aegypti (L) effectively and economically. "DMR-larval trap" is a mechanical device and is capable of trapping all stages of larvae and pupae and that the number of aquatic stages trapped is directly proportional to the number of larvae and pupae present in the container-habitat. The trap is also capable of trapping greater number of late stages than the earlier ones which is more favourable from control point of view. It is found to trap about 47.85 per cent of all larvae and pupae within the first 24 hours achieving complete control within 10 days with sustained control thereafter.
