Synopsis

Excerpt from The Potential for Genetic Suppression of Insect Populations by Their Adaptations to Climate

Examination of cases 2-6 in table 41 shows that when a conditional lethal trait is deter mined by more than one gene, the trait may be expressed in a progressively higher proportion of individuals from generation to generation. Cases 7 - 15 show that when the release strain possesses more than one conditional lethal trait, the efficiency of suppression is progressively augmented in succeeding generations. If the conditional lethal traits were expressed in the last generation of the season, release ratios ranging from to would be adequate to decimate most populations with four genera tions per year. This would require releases ranging from 100 to 500 insects per acre when the natural population consists of 10 insects per acre. Higher ratios would be required if the species had fewer than four generations per year. In most instances these ratios would have to be two to five times higher to achieve the same suppression in the F2 as in the F4.
