Abstract

The relationships between Cinara Cupressobium aphids inhabiting woody parts and leaves of conifers belonging to Cupressaceae have been studied using a mitochondrial gene COI and a nuclear gene EF1-α. Based on the COI sequences, genetic distances between species ranged from 5.6 % between Cinara C. tujafilina del Guercio and Cinara C. juniperi De Geer to 10.5 % between C. C. tujafilina and Cinara C. mordvilkoi Pašek. Genetic distances among EF1-α sequences were lower and showed from 0.1 % between C. cupressi and C. juniperi to 2.3 % between C. tujafilina and C. mordvilkoi. Molecular phylogenetic trees were constructed using the Bayesian inference BI phylogenetic analysis and maximum parsimony MP criterion. Phylogenetic trees obtained based on COI and EF1-α marker genes created two sister clades. Our results indicate that Cinara Cupressobium are a monophyletic group of aphids. Phylogenetic relationships amongst Cupressobium aphids do not result from the association with the host plant, but from the feeding site on the host plant or an ability to change the microhabitat on the plant. As closely related species inhabit similar microhabitats on different host plants, it suggests that the host switching is the main mode of speciation in this subgenus.
