ABSTRACT
A preliminary screening of crude acetone extract of Cuscuta hyalina Roth. was conducted against the laboratory reared preadult stages of common house mosquito Culex quinquefasciatus (Say) (Diptera Culicidae). 24 h LC50 of third and fourth instar larvae and pupae were 303 ppm, 306.44 ppm and 97.66 ppm respectively. The extract completely restrained the adult mosquito emergence at sublethal doses (50 ppm for third instar and 75 ppm for fourth instar), by disrupting the normal morphogenesis. The extract was found to be an effective oviposition deterrent at 80 ppm. The plant was also found to be effective in suppressing the adult emergence when directly sprinkled as dry powder on the water surface.
