Dalotia coriaria

The Greenhouse Rove Beetle (Dalotia coriaria) is a species of staphylinid rove beetle in the subfamily Aleocharinae. It is used as a predatory biological control agent for the management of pest insects.

Biological control

Dalotia coriaria (Kraatz, 1856) is a commercially available species, sold by several Integrated Pest Management companies in the USA and Europe. The beetles are employed as a biological control agent of glasshouse pests. Both adults and larvae prey upon larvae of fungus gnats (Bradysia spp.), and adult beetles also target shore flies (Scatella spp.) and thrips.[1] The species was discovered feeding on a laboratory culture of fungus gnats, stimulating a study into its efficacy as a biological control agent.[2]

Use as a model organism

Dalotia's fast generation time, high fecundity and ease of culture of have recently led to the species being developed as a laboratory model organism.[3]

Taxonomic history

Like many Aleocharinae, Dalotia coriaria has a complex taxonomic history. Initially described a member of Homalota,[4] many authors placed it in the large genus Atheta, before its current placement in Dalotia.[5]
