ABSTRACT
The detection and analysis of genetic variation in natural and laboratory populations of pest insects are reviewed. The application of population genetic methods and theory can help to plan and evaluate the implementation of area-wide integrated pest management (AW-IPM) programmes that use the sterile insect technique (SIT). Population genetic studies can play an important role in estimating dispersal rates and thus the degree of isolation or gene flow among target populations, determining if sibling species exist, establishing the origin of outbreaks or reintroductions, and supporting the quality control of mass-reared colonies. The target’s population history may be examined in terms of “bottlenecks”, range 530fragmentations, and expansions. Genetic methods can be helpful in distinguishing wild insects from released sterile or semi-sterile ones, and in ascertaining, together with mating compatibility studies, the compatibility of mass-reared colonies with target wild insects.
