Table 28. --Complete suppression of native population (2,000 insects, 1:1 sex ratio) by overflooding parental, F\ , 

 F 2 , and F3 generations with partially sterile release strain bearing conditional lethal traits. Complete 

 suppression is assumed when number of insects with genotypes for survival is reduced to 30 or less 



Inheritance of conditional No offspring from partially Proportionate offspring from partially 



lethal traits in sterile insect matings when sterile insect matings when lethal
