POTENTIAL FOR GENETIC SUPPRESSION OF INSECT POPULATIONS 



25 



Table 9. — Theoretical population and genotypic trends when native population of 

 2,000 insects (aa) is overflooded by 198,000 or 396,000 partially sterile 

 insects (AA) during parental, F, , F2 , and F_ generations. Matings between 

 partially sterile insects are assumed to yield offspring proportionate to 

 sterilitv level
