1 - 58 . (canceled)
59 . A composition for improving the stability of dsRNA for control of an arthropod parasite of honeybees, comprising:
a. a dsRNA that comprises a sequence that is complementary or identical to at least 21 contiguous nucleotides of a Varroa destructor messenger RNA (mRNA);
b. a carbohydrate; and
c. one or more food grade preservatives
60 . The composition of claim 59 wherein the one or more food grade preservatives is selected from the group consisting of a sorbate, a sorbate salt, potassium sorbate, sorbic acid, a benzoate, a benzoate salt, sodium benzoate, benzoic acid, citric acid or a tocopherol.
61 . The composition of claim 60 , wherein the composition comprises two or more food grade preservatives selected from the group consisting of a sorbate, a sorbate salt, potassium sorbate, sorbic acid, a benzoate, a benzoate salt, benzoic acid, citric acid or a tocopherol.
62 . The composition of claim 61 wherein the carbohydrate is selected from the group consisting of arabinose, dextrose, fructose, fucose, galactose, glucose, inositol, lactose, maltose, mannitol, mannose, rhamnose, ribose, sorbitol, sucrose, trehalose, xylose, high fructose corn syrup, high maltose corn syrup, sugar syrup, inverted sugar syrup, and any combination thereof.
63 . The composition of claim 62 wherein the carbohydrate is sucrose.
64 . The composition of claim 63 wherein the two or more food grade preservatives comprise sodium benzoate and potassium sorbate.
65 . The composition of claim 60 further comprising a vitamin selected from the group consisting of vitamin A, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B7, vitamin B9, vitamin B12, vitamin C, vitamin D, vitamin E, and vitamin K
66 . The composition of claim 65 wherein the vitamin comprises vitamin C.
67 . The composition of claim 64 wherein the sucrose is present in an amount of from about 65% to about 88% by weight based on the total weight of the formulation.
68 . The composition of claim 67 wherein the potassium sorbate is present in an amount of from about 0.05% to about 0.15% by weight based on the total weight of the formulation.
69 . The composition of claim 68 wherein the potassium benzoate is present in an amount of from about 0.05% to about 0.15% by weight by weight based on the total weight of the formulation.
