ABSTRACT
Studies of insect reproduction, from the early 1900s to the present time, have demonstrated that insects treated with X-ray or gamma radiation (or with certain mutagenic chemicals) are unable to produce a normal number of living progeny [57]. Treated insects (which may be completely or only partially sterile) are released in large numbers into a field environment and are expected to mate with the feral insects, thus interfering with reproduction. If matings between treated insects and normal insects are successful, reproduction of the field populations will be disrupted, and the population will decline.
