Induction and inheritance of chromosome rearrangements in the Hessian fly (Diptera Cecidomyiidae)
Annals of the Entomological Society of America 90 (4), 480-486
Abstract: Pupae of male Hessian flies, Mayetiola destructor (Say), were exposed to 4 different doses of gamma radiation (0.0, 15, 30, 40, and 60 Gy) and mated to untreated females. The fertility of these females and their F1, F2, and F3 offspring were evaluated. Incomplete fertility (semisterility) in several lines segregated as a dominant genetic marker, indicating that semisterility could be used as a dominant phenotypic marker to follow the inheritance of chromosome rearrangements in these lines. To further test this possibility, polytene chromosomes of 26 progenies produced by semisterile females derived from 40 Gy exposed males were examined for the presence of chromosome rearrangements. Three independent rearrangements were identified among the larvae in these progenies and these are described. Radiation-induced semisterility, therefore, can be used as a dominant genetic marker for chromosome rearrangements in the Hessian fly.
