The article focuses on experiments performed in the laboratory and the field on the Lewis spider mite and the two-spotted spider mite. Tests were performed to evaluate the effectiveness of four types of predatory mites in controlling both kinds of spider mite. Miticide efficacy was also tested on the Lewis spider mite in bioassays.
These mites can cause serious damage to strawberry and other agricultural crops with subsequent financial loss to growers. Spider mite research is particularly relevant to Ventura County where strawberry production is the top crop grown and spider mite infestations have been on the rise.
Anna Howell is an experienced entomologist who has contributed her efforts to many research projects here at UCCE Ventura. Dr. Daugovish is UCCE's strawberry and vegetable crop adviser whose applied research benefits county growers and is an active contributor to "Strawberry Disorders: Identification and Management" website, a resource for assisting in diagnosing problems in strawberry.
