Distribution, host range and host preferences of Dinocampus coccinellae (Hymenoptera: Braconidae): A worldwide database

Abstract

Dinocampus coccinellae (Schrank) is a braconid parasitoid of ladybird beetles (Coleoptera: Coccinellidae) and has exceptionally wide geographical and host ranges. Based on published and unpublished sources Dinocampus coccinellae probably occurs throughout the temperate, subtropical and tropical climatic zones, but some regions, such as sub-Saharan Africa (except its southernmost part) and the Malay Archipelago, have not so far been surveyed for this wasp. In most of its extensive range D. coccinellae was present before the widespread use of classical biological control. It is likely, however, to have reached some oceanic islands and archipelagos at a later date, along with ladybirds used as biocontrol agents. At least 72 species of Coccinellidae are hosts of D. coccinellae. Three of them, Vibidia duodecimguttata (Poda), Calvia decemguttata (L.) and Coccinella miranda Wollaston, are reported here for the first time as hosts of this parasitoid. The most often reported host of D. coccinellae worldwide is Coccinella septempunctata L. followed by Harmonia axyridis (Pallas), Coleomegilla maculata (De Geer) and Hippodamia convergens Guerin.
