Embodiment 1

[0024] The bait for killing red fire ants in this embodiment includes 0.05 gram of fipronil, 0.5 gram of ethyl cellulose, 0.35 gram of paraben complex ester, 50 gram of tapioca flour, 20 gram of brown sugar, 10 gram of biscuit powder and 19.1 gram of water.

[0025] The preparation method of this bait for killing red imported fire ants is as follows: Weigh each raw material according to the above weight, dissolve fipronil and ethyl cellulose with a mixed solution of absolute ethanol and dichloromethane, wherein, absolute ethanol and dichloromethane The volume ratio of methane is 1:1, remove absolute ethanol and dichloromethane to obtain ethyl cellulose clathrate, crush the resulting clathrate into powder, and then mix with paraben complex ester, tapioca flour, brown sugar, biscuits Mix the powder and water evenly, and stir for 1 hour to obtain the bait for killing red imported fire ants.

Embodiment 2

[0027] The bait for killing red fire ants in this embodiment includes 0.2 gram of fipronil, 0.1 gram of ethyl cellulose, 0.2 gram of paraben complex ester, 60 gram of tapioca flour, 10 gram of brown sugar, 15 gram of biscuit powder and 14.5 gram of water.

[0028] The preparation method of this bait for killing red imported fire ants is as follows: Weigh each raw material according to the above weight, dissolve fipronil and ethyl cellulose with a mixed solution of absolute ethanol and dichloromethane, wherein, absolute ethanol and dichloromethane The volume ratio of methane is 1:1, remove absolute ethanol and dichloromethane to obtain ethyl cellulose clathrate, crush the resulting clathrate into powder, and then mix with paraben complex ester, tapioca flour, brown sugar, biscuits Mix the powder and water evenly, and stir for 1 hour to obtain the bait for killing red imported fire ants.

Embodiment 3

[0030] The bait for killing red fire ants in this embodiment includes 0.1 gram of fipronil, 0.1 gram of cyclodextrin, 0.3 gram of paraben complex ester, 55 grams of tapioca flour, 10 grams of brown sugar, 20 grams of biscuit powder and 14.7 grams of water.

[0031] The preparation method of the bait for killing red imported fire ants is as follows: each raw material is weighed according to the above weight, and fipronil is dissolved in ethyl acetate solution for later use. Add cyclodextrin and purified water to heat to form a saturated solution, and immediately transfer it to an ultrasonic reaction device after the cyclodextrin is completely dissolved, and slowly add fipronil dissolved in ethyl acetate to the cyclodextrin saturated solution, After the sonication is completed, cool down overnight, wash the precipitated precipitate with absolute ethanol, suction filter, and vacuum-dry to obtain the cyclodextrin inclusion compound, and then mix the cyclodextrin inclusion compound ...

Abstract

The invention discloses a bait capable of killing solenopsis invicta. The bait comprises an insecticidal component, a preservative, attractants, water and an inclusion agent used for including the insecticidal component. The bait has the beneficial effects that the inclusion agent is adopted to include the insecticidal component, so that the degradation velocity and poisoning velocity of the insecticidal component can be reduced so that solenopsis invicta dies of slow poisoning after being fed, and then the alert of solenopsis invicta which is not fed to the bait is eliminated, thus killing solenopsis invicta in large area; the insecticidal component in the bait is more than the lethal dose of solenopsis invicta, so that the killing effects are obvious.

Description

technical field [0001] The invention relates to the technical field of insecticidal baits, in particular to a bait for killing red fire ants. Background technique [0002] The red fire ant belongs to the Formicidae insects of the order Hymenoptera. Its body is brownish red, and its body size is larger than that of ordinary ants. The adult body is 3 mm to 6 mm long. The red fire ant is one of the most destructive invasive organisms listed by the International Union for Conservation of Nature, and it has huge damage to humans, animals and plants. RIFA originated from South America and was introduced to the United States in the 1930s. It spread from the United States to Australia and Taiwan through containers and turf in the early 21st century, and then was introduced from Taiwan to Wuchuan City, Guangdong Province, China through household waste. , and then spread to other cities in the province as well as Hong Kong and Macau. [0003] RIFA has strong adaptability, miscellane...
