Abstract

Compositions and methods for disinfecting bee colonies for preventing or treating diseases in honey bees, honey bee larvae and honey bee hives are disclosed. Such diseases may arise from a variety of sources, including bacteria, fungi, viruses, protozoa and parasites in the hive. Representative diseases preventable or treatable by this invention include Foulbrood and Chalkbrood. The compositions of the present invention include a protic acid and a chlorite ion, and may further include other optional components such as a gelling agent, colorant and/or preservative. Methods disclosed herein include applying the composition to a surface of a bee-hive. Honey produced by bees administered a composition of this invention is also disclosed.

Claims

1. A method for preventing or treating a disease associated with honey bees, honey bee larvae or honey bee hives, wherein the disease arises from a source selected from a bacteria, a fungi, a virus, a protozoa and a parasite, comprising administering to the honey bees, honey bee larvae or honey bee hives an effective amount of an aqueous composition comprising a protic acid and a chlorite ion.

2. The method of claim 1 wherein the disease arises from a bacterial source that causes American Foulbrood or European Foulbrood.

3. The method of claim 1 wherein the disease arises from a fungal source that causes Chalkbrood.

4. The method of claim 1 wherein the disease arises from a protozoan source that causes Nosema.

5. The method of claim 1 wherein the parasitic source is a mite which causes a disease selected from Varroasis and Acariosis.

6. The method of claim 1 wherein the disease arises from a viral source that causes Sacbrood Disease.

7. The method of claim 1 wherein administration is accomplished by applying the composition to a honey bee hive.

8. The method of claim 7 wherein the composition is sprayed on or in the honey bee hive.

9. The method of claim 7 wherein the composition is applied to an internal surface of the honey bee hive.

10. The method of claim 7 wherein the composition is applied to the surface of a substrate inserted into the honey bee hive.

11. The method of claim 10 wherein the substrate is selected from a bottomboard of the hive, a topboard of the hive, and a flat surface introduced over the top or bottomboard of the hive.

12. The method of claim 7 wherein the composition is located in a reservoir internal to the hive.

13. The method of claim 1 wherein the protic acid is an organic acid.

14. The method of claim 13 wherein the organic acid as the structure:

##STR2## where R₁ and R₂ are the same or different, and independently selected from --H, --CH₃, --CH₂ COOH, --CH₂ OH, --CH₂ (OH)COOH and --C₆ H₅ ; and

R₃ is selected from --OH and --H.

15. The method of claim 14 wherein R₃ is --OH, and the pK of the organic acid ranges from about 2.8 to about 4.2.

16. The method of claim 15 wherein the organic acid is selected from citric acid, malic acid, tartaric acid, glycolic acid, mandelic acid, lactic acid, and mixtures thereof.

17. The method of claim 14 wherein R₃ is --H, and the pK of the organic acid ranges from about 4.0 to about 5.0.

18. The method of claim 17 wherein the organic acid is selected from formic acid, acetic acid, and mixtures thereof.

19. The method of claim 1 wherein the protic acid is an inorganic acid.

20. The method of claim 19 wherein the inorganic acid as a pK ranging from about 0 to about 2.2.

21. The method of claim 20 wherein the inorganic acid is selected from sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, and mixtures thereof.

22. The method of claim 1 wherein the protic acid is present in the composition in an amount ranging from about 0.005% to 10% by weight of the composition.

23. The method of claim 15 wherein the organic acid is present in the composition in an amount ranging from 0.1% to 2% by weight of the composition.

24. The method of claim 17 wherein the organic acid is present in the composition in an amount ranging from 0.1% to 5% by weight of the composition.

25. The method of claim 19 wherein the inorganic acid is present in the composition in an amount ranging from 0.005% to 0.5% by weight of the composition.

26. The method of claim 1 wherein the chlorite is a metal chlorite.

27. The method of claim 16 wherein the metal chlorite is sodium chlorite.

28. The method of claim 1 wherein the chlorite ion is present in the composition in an amount ranging from 0.01% to 1.0% by weight of the composition.

29. The method of claim 1 wherein the chlorite ion is present in the composition in an amount ranging from 0.1% to 0.65% by weight of the composition.

30. The method of claim 1 wherein the composition is provided as a two-part composition, wherein the first part comprises the protic acid and the second part comprises the chlorite ion.

31. The method of claim 30 wherein the two-part composition is combined immediately prior to administration.

32. The method of claim 1 wherein the composition further comprises an agent selected from a gelling agent, a preservative and a colorant.

33. The method of claim 1 wherein the composition is in the form of a gel.

34. The method of claim 1 wherein the composition is in the form of a liquid.
