dc.description.abstract The Sterile Insect Technique (SIT) is often used to suppress or eradicate populations of invading pest species of true fruit flies (Tephritidae). The success of the SIT depends largely on the ability of mass-reared, sterile males to compete successfully against wild males to obtain copulations with wild females. In addition, as females are often polyandrous, sterile males should inhibit female remating to a degree similar to that effected by wild males. The objective of this study was to determine whether sterile males of a genetic sexing strain of the oriental fruit fly, Bactrocera dorsalis (Hendel) inhibited the remating propensity of wild females to the same degree as wild males. Females were first mated with either a sterile male from the laboratory strain or a fertile wild male. Mated females were then held 1, 10, or 20 d, then offered wild males for mating, and the incidence of rematings was scored. For each time interval, remating level was higher for females first mated to sterile, laboratory males than fertile, wild males. In addition, independent of the identity of the first male mating partner, the incidence of female remating increased with time elapsed since the initial mating. Results are compared with similar studies on other pest tephritid species. en_US
