The present invention relates to a formula or composition for use in reducing a honey bee parasitic mite infestation that may comprise, for example, a liquid, solid, or paste composition, comprising about 5-20% beta acids (about 5-75% by weight), about 5-75% by weight propylene glycol, about 5-75% by weight polysorbate 60, about 0.5-35% of a thixotropic material comprising, for example, fumed silica, and/or about 0.5-5% of an antioxidant comprising, for example, ascorbic acid, the composition is active against parasitic mites for more than about 14 days in the bee hives. Compositions of the present invention provide effective control, treatment, or prevention of honey bee parasitic mite infestation by inclusion of, for example, certain excipients that retard beta acid oxidation, prolong availability of active ingredient for bee uptake, improve convenience for beekeepers, or both retard beta acid oxidation and prolong the availability of active ingredient for bee uptake.
A composition comprising about 5% to about 75% by weight hop beta acids, about 5% to about 29% by weight solvent, about 5% to about 75% by weight emulsifier, and about 0.5% to about 35% by weight fumed silica, wherein the hop beta acid degradation is about 30% over a period of about 30 days, and wherein the composition is moist for a period of at least about 14 days.
A composition comprising about 5% to about 75% by weight hop beta acids, about 5% to about 75% by weight solvent, about 5% to about 75% by weight emulsifier, and about 0.5% to about 6% by weight fumed silica, wherein the hop beta acid degradation is about 30% over a period of about 30 days, and wherein the composition is moist for a period of at least about 14 days.
