Abstract
The present invention relates to methods and compositions comprising viable spores of Bacillus thuringiensis (Bt) strains for controlling or reducing mite infestations, such as the control and reduction of infestations produced by Dermanyssus gallinae (poultry red mite).
Claims21
A pharmaceutical or biocide composition suitable for controlling or reducing mite infestations, comprising as an active ingredient a bacterial isolate of at least one strain of Bacillus thuringiensis (B. thuringiensis), wherein the bacterial isolate comprises an effective amount of viable spores of at least said one strain of B. thuringiensis;
- and wherein:
- (a) the at least one strain of B. thuringiensis is a strain that produces less than 1.7 mg/ml of B. thuringiensis' non-spore proteins for every 3.1×109 viable spores per ml;
- and
- (b) the pharmaceutical or biocide composition is in a pharmaceutical form selected from the group consisting of:
- dust, powder, granular formulation, microencapsulated formulation, lotion, ointment, gel, cream, paste, suspension, liquid concentrate, solution and emulsion.
