Studies on the biological control of the sheep scab mite Psoroptes ovis using entomopathogenic fungi - CB01022

Description
This was a project led by the Veterinary Laboratories Agency to which DETR and subsequently Chemicals & GM Policy Division in Defra contributed.

Ectoparasites are an important cause of disease in animals and present control strategfies rely heavily on the use of several neurotoxic chemicals which pose problems of human and environmental toxicity. The emergence of resistant strains further limits effective control of a number of species. This project investigated an alternative method of control using entomopathogenic fungi. There has been no previous attempt to control ectoparasitic mites with fungi but there are sound theoretical arguments to suggest that parasitic mites may form an ideal target for such biological control agents.

Objectives
- the qualitative production of defined fungal strains
- the development of bioassays
- the development of formulations for delivery of identifed fungal strains
- preliminary studies to determine the effectiveness of entomopathogenic fungi in controlling mite infestations on sheep
