Özet

The meadow spittlebug Philaenus spumarius (L.) exhibits a striking dorsal colour/pattern polymorphism throughout its distribution in the Holarctic region. At least 16 different dorsal colour morphs have been reported from several European and North American populations. It is also abundant in New Zealand, but only two different forms—flavicollis(FLA) and ypicus(TYP)—are expressed by the two different alleles, "F”and "t”respectively. This paper describes the laboratory crossing experiments performed on the inheritance of the FLA and TYP phenotypes in New Zealand populations of Philaenus spumarius. A total of 431 progeny from 25 successful crosses using New Zealandmaterial clearly show that FLA is dominant over TYP in bothsexes, as established in British P. spumariuspopulations. But the model of inheritance found in New Zealand populations of P. spumarusdiffers from that in previously studied Fennoscandian populations, where there is a reversal dominancein the sexes involving FLA and TYP. © 2000 Taylor & Francis Group, LLC.
