The population density was clarified in Larva Index : Container Index (C.I), House Index (H.I) and Bretaeau Index (B.I). Larva survey was done by a single larva method. populatio…
By bioassay Aedes aegypty larvae collected from Yogyakarta were found to be susceptible to temphos and malathion and by using microplate nzymatic assay Ae. aegypti larvae collected from the same sites were potentially resistant to the organoposphate insecticides due to elevated esterase activity in hydrolyzing alpha-naphthyl acetate substrate used in the enzymatic reaction from the same sites m…
The effect of the insecticide permethrin 100 EC on Ae. aegypti, the vector for dengue Hemorrhagic Fever, was studied at the Entomology Laboratory, Health Research and Development of Health.
