Biochemical systematics of the Phyllotreta cruciferae complex (Coleoptera : Chrysomelidae : Alticinae)
Annals of the Entomological Society of America 92 (1), 30-39
Abstract: The biochemical systematics of 6 closely related species: Phyllotreta aerea Allard, 1859, P. astrachanica Lopatin, 1977, P. atra (F., 1775), P. consobrina (Curtis, 1837), P. cruciferae (Goeze, 1777) and P. nigripes (F., 1775) were studied. This study is on the genetics and biochemical systematics of these 6 economically harmful species, including several populations of each species. Material from 27 populations divided over 6 species (>3,500 specimens) was used for allozyme electrophoresis. An allozyme-based determination key was constructed. Genetic variability measures for the different populations were calculated; Rogers modified distances and Cavalli-Sforza and Edwards arc distances between each pair of populations are presented. Unweighted pair-group method with arithmetic average and distance Wagner trees based on Rogers and Cavalli-Sforza and Edwards arc distances show slightly different topologies. Two major clusters (P. aerea/P. consobrina and P. atra/P. cruciferae) are found in all dendrograms, but the positions of P. astrachanica and P. nigripes leave some room for discussion.
