Surveys for ladybirds (Coleoptera: Coccinellidae) in Switzerland and confirmation of the presence of the invasive alien ladybird species, Harmonia axyridis (Pallas)
Mitteilungen der Schweizerischen Entomologischen Gesellschaft 80, 7-14
Abstract: Surveys were carried out in Switzerland in 2005 and 2006 to make observations on the indigenous ladybird community and to monitor the presence of the harlequin ladybird, Harmonia axyridis Pallas, an Asian species presently invading Europe. Ladybirds were collected by beating the branches of trees and shrubs, sweeping grasslands and using black-light traps. Twenty-nine species were found, mainly through beating branches and sweeping grasslands. H. axyridis was not found in 2005. In 2006 its presence was recorded in ten cantons and it was particularly abundant in the region of Basel.
