234.  Derived from:  Legner, E. F.  1987.  Some quantitative aspects of inheritance in breeding synanthropic fly parasitoids.  Bull. Soc. Vect. Ecol. 12(2);  528-533. 

 

Summary

 

          The inheritance of solitary and gregarious development in two strains of Muscidifurax raptorellus Kogan & Legner appears quantitative, as successive backcrosses of hybrids to original parental males result in additive intensities of trait expression.  The magnitude of each increase is dependent on the number of backcrosses that are performed to create the hybrid, the particular "load" of backcrosses that a hybrid possesses determining the degree to which the next mating will affect behavior.  The curve for increasing expression of behavior appears sigmoid.  Females changed their behavior significantly following mating. Observed behavior involves differences in offspring survival.  For biological control the liberations of parasitoid males possessing certain desirable traits, such as high fecundity or parasitization rates may be desireable for biological control.
