Effect of ivermectin on survival and fecundity of culex pipiens the vector of wuchereria bancrofti in Egypt

ABSTRACT

The effect of two different doses of ivermectin on the survival and fecundity of Culex pipiens was evaluated. Female mosquitoes [50 in each group, same age and generation] were fed once on blood from ivermectin-treated rabbits. Comparative treatments consisted of two different doses of ivermectin [0.1 mg or 0.4 mg/kg of body weight] and mosquito groups were fed on the rabbits at 3 days and 10 days post-treatment, respectively. Mosquitoes were maintained with 10% sucrose solution at 25C and 70% relative humidity. Observations were made at 7, 10, 15, 20, 25 and 30 days post-feeding. These results provided new information about the effect of ivermectin on the vector of lymphatic filariasis and added a new dimension to the use of ivermectin in filariasis control
