A recent computer simulation model by Levins and Parker (1983) indicated that mass releases of male-sterile Heliothis hybrid moths could cause genetic suppression of the tobacco budworm, Heliothis virescens, without the risk of significant crop damage. We present an analytical model to explore the behavior of the Levins-Parker model. Our model shows that the length of time between matings for females when they mate with wild type fertile males to that when they mate with hybrid sterile males is extremely important to the efficacy of a suppression program. Release ratios needed to suppress a natural pest population were examined across a range of biological parameters.
