Microsatellite Polymorphism Suggests High Genetic Diversity But Disrupted Gene Flow in the Two-Spot Ladybird Adalia bipunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae) Populations from Diverse Environments

The two-spot ladybird Adalia bipunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae) is a widely distributed generalist, feeding preferably on aphids. The species inhabits various environments, including anthropogenic landscape, where pollution and microclimate enables to attain very high numbers of favorite prey. Recently, the abundance of the two-spot ladybird has declined, mainly as an after-effect of invasion of the competing species — the...
