Abstract

Disclosed are compositions and methods of pest control. The composition contains one or more active agents such as a polyalcohol, carbohydrate, nucleobase or nucleotide compound or derivative and one or more inactive ingredients which function as attractants or nutrients. The combination of the active agent(s) and the inactive ingredients achieves synergistic effect in pest control.

Claims (8)

1. A method of mosquito control comprising feeding a population of mosquitos with a composition comprising one or more active agents, and one or more attractants or nutrients,

wherein the active agent includes 3-fluoropropane-1,2-diol, 2-amino-1,3-propanediol, 1,1-bis(hydroxymethyl)cyclobutene, 3 -bromopropane-1,2-diol, 3-chloro-1,2-propanediol, 1,2-cyclohexanediol, 2′-deoxy-5-fluorouridine, 4-deoxy-4-fluoro-β-D-glucopyranose, 2,2-dimethyl-1,3-propanediol, 2,3-dimethylbutane-2,3-diol, 2-fluoroadenine, 2-fluoroadenosine, gemcitabine, 2-methyl-1,3-propanediol, 2-penyl-1,3-propanediol, or 2-chloropropionic acid, and

wherein the one or more attractants include a food attractant, a sex attractant, an olfactory attractant, or an environmental attractant.

2. The method of claim 1 , wherein the concentration of the one or more active agents is from 0.001% to 1%, from 0.1% to 25%, from 0.5% to 20%, from 1% to 15%, from 3% to 10%, or from 5% to 8% of the total weight of the composition.

3. The method of claim 1 , wherein the composition comprises a combination of four or more attractants that include sucrose, dextrose, sodium citrate, citric acid, sodium monobasic phosphate, or adenine.

4. The method of claim 1 , wherein the environmental attractant includes pH, light, sound, vibration, wind, heat, humidity, or gas.

5. The method of claim 1 , wherein the concentration of the one or more attractants is from 0.001% to 1%, from 1% to 50%, from 5% to 45%, from 10% to 30%, or from 15% to 25% of the total weight of the composition.

6. The method of claim 1 , wherein the composition kills at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or about 100% of the population of the mosquitos upon ingestion of the composition.
