Efficacy of some plant extracts on larval mortality of Culex quinquefasciatus in water solvent after 24 hr 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. Each plant extract was tested in five concentrations i.e. 200, 300, 500, 700 and 1000ppm. The results indicated significant differences in Cx. quinquefasciatus mortalities caused by treatments and control. Lemon juice in water extract yielded higher Cx. quinquefasciatus mortalities of 42% after 24 hours. LC50 value was highest for bitter gourd (1593.96) and lowest for lemon juice (630.50) while LC95 value was highest for bitter gourd (66749.45) and lowest for lemon grass (2535.34) after 24 hrs in water extract. The study recommends that the plant extracts should be tested at lower concentrations as they have shown mortalities on different doses but many of the extracts yielded 100% mortalities at higher concentrations.
