Abstract:

Groups of Aedes aegypti female mosquitoes were fed 0.25 and 0.025 concentration of apholate and metepa. Four days later they were fed a solution containing VEE virus and sweetened blood. Male mosquitoes were introduced also at this time. Treatment with the 0.25 concentrations of either chemosterilant completely inhibited oviposition. Both the total number of eggs and per cent of viable eggs in the 0.025 sterilant-treated groups were a fraction of those oviposited by the untreated groups. Mortality in the treated vectors, especially those given the 0.25 concentrations, was higher than that of the untreated mosquitoes. The lower concentrations of chemosterilants had no demonstrable effects on vector susceptibility to VEE virus or on subsequent virus transmission, but both characteristics were significantly influenced by the higher concentrations of both compounds. The results suggest that other mosquito vector - arbovirus combinations could demonstrate similar or greater increased potentials. Author
