Culex quinquefasciatus vectors Wuchereria bancrofti, which causes Lymphatic filariasis, a hurting and extremely disfiguring disease, in millions of people in tropical and subtropical areas of the world each year. Synthetic insecticides have been mainly used for the control of the insect vector. In the present research efficacy of some plant extracts in ethanol solvent on larval mortality of C. quinquefasciatus after 24 hrs was tested at the Nuclear Institute for Food and Agriculture (NIFA), Peshawar during 2013. LC50 and LC95 values of the plant extracts were also determined. The experiment was laid out in CR Design with 6 treatments, i.e. lemon juice, lemon grass, basil, thyme, fruit of bitter gourd and control, each replicated three times. The plant extracts were tested each in five concentrations of 200, 300, 500, 700 and 1000 ppm. The results indicated significance differences in C. quinquefasciatus mortalities caused by different treatments and control. Thyme and bitter gourd gave 100% mortalities of the insect at all the concentrations in ethanol extract. LC50 value was highest for lemon juice (694.004) and LC95 value was highest for basil (7102.726) after 24 hrs in ethanol extract. The study recommended that the plant extracts should be tested at lower concentrations as many of the extracts yielded 100% mortalities at higher concentrations.
