![]() ![]() We found late-acting lethality to be considerably more effective than early-acting lethality. We investigated by mathematical modeling the effect of manipulating the stage of development at which death occurs (lethal phase) in an SIT program against a density-dependence-limited insect population. Additionally, vector populations with strong density-dependent effects will tend to be resistant to SIT-based control as the population-reducing effect of induced sterility will tend to be offset by reduced density-dependent mortality. SIT has not been widely used against insect disease vectors such as mosquitoes, in part because of various practical difficulties in rearing, sterilization and distribution. One potential method for environmentally-friendly, species-specific population control is the Sterile Insect Technique (SIT). Reduction or elimination of vector populations will tend to reduce or eliminate transmission of vector-borne diseases. ![]()
