Total per cent inhibition of emergence of Ae. aegypti larvae exposed to varying concentrations of methoprene. Effect of methoprene (0–0.08 ppm) on the late third instar Ae. aegypti larvae (N = 60–110) reared from field-collected eggs from the eastern parishes of Jamaica in comparison to the susceptible Rockefeller strain. The data are summarized as total inhibition of emergence per population.
