Abstract:The fecundity and fertility of two strains of plum curculio, Conotrachelus nenuphar (Hbst.), the reciprocal crosses and the F1 generations were compared under laboratory conditions. The two strains were a laboratory strain reared continuously from a culture collected from the area of Raleigh, North Carolina in 1949 and a northern strain collected in the field at Geneva, New York. The laboratory strain is characterized by continuous reproduction under laboratory conditions while the northern strain requires hibernation to initiate ovipositon. The laboratory strain produced significantly more eggs than the northern strain with fertility being equal. The northern female X laboratory mule cross resulted in significantly lower fertility and fecundity than the reciprocal cross. In the F1 generations, fertility was normal with reduced fecundity in the F1 laboratory ♀ X northern ♂ cross.
