Embodiment 1

[0018] With chlorpyrifos as the insecticidal active ingredient, the proportioning range of each component is selected as follows:

[0019] 0.02% chlorpyrifos; 0.6% polyurea; 76% fried flour; 18.27% peanut oil; 5% white sugar; 0.01% sodium benzoate.

[0020] When preparing, first mix fried flour, peanut oil, white granulated sugar and sodium benzoate in proportion to form mixture A, and prepare insecticidal active ingredient chlorpyrifos into microcapsule aqueous suspension by interfacial polymerization method, and spray evenly on mixture A in proportion. Can.

[0021] Chlorpyrifos is a phosphorothioate insecticide with contact, stomach poisoning and fumigating effects. The original drug of chlorpyrifos has a mercaptan odor. If the original drug is directly formulated into a bait, it will repel RIFAs and fail to achieve the effect of allowing RIFA workers to actively feed and carry them. Chlorpyrifos is made into microcapsules and wrapped in a capsule formed by polymer materi...

Embodiment 2

[0023] With rotenone as the insecticidal active ingredient, the proportioning range of each component is selected as follows:

[0024] 0.4% rotenone; 0.8% polyamide; 75% fried flour; 19.78% peanut oil; 4% white sugar; 0.02% sodium dehydroacetate.

[0025] When preparing, first mix fried flour, peanut oil, white granulated sugar and sodium benzoate in proportion to form a mixture A, and prepare the insecticidal active ingredient rotenone into a microcapsule water suspension by interfacial polymerization, and spray evenly on the mixture A in proportion. Can.

[0026] Rotenone is an insecticidal active ingredient extracted from the roots of the leguminous Ruteng plant in tropical and subtropical Asia. It has no phytotoxicity, no residue, no pollution to the environment, and no great harm to humans and animals. Rotenone has a strong contact and stomach poisoning effect, making the pests have difficulty breathing, weakness, slow heartbeat, affecting the respiratory metabolism of t...

Abstract

The invention relates to the technical field of solenopsis invicta buren control preparation; the solenopsis invicta buren contains the following constituents by mass percentage: 0.01-0.6 percent of insecticidal active constituents including chlopyrifos or nicouline; 0.001-1 percent of microcapsule membrane material; 75-78 percent of fried flour, 15.37-21.979 percent of peanut oil, 3-5 percent ofwhite granulated sugar or brown sugar, and 0.01-0.03 percent of preservative. The bait has good insecticidal effect to the solenopsis invicta buren injurious insects, and the insecticidal active constituents which can not be prepared into bait directly are prepared into microcapsule water suspension, and then the solenopsis invicta buren bait is prepared, thereby not only covering the odor which is not loved by solenopsis invicta buren in the production of the solenopsis invicta buren bait, but also reducing the contact toxicity, inhalation toxicity and phytotoxicity of the preparation; indoorpesticide effect experiments and field tests are carried out in the invention, so as to prove that the solenopsis invicta buren bait has good control effect to the solenopsis invicta buren.

Description

technical field [0001] The invention relates to the technical field of fire ants control agents. Background technique [0002] The red fire ant (Solenopsis invicta Buren) is native to Brazil, Paraguay, and Argentina in the Parana River Basin in South America. It has strong fecundity and competitiveness. Once it enters a new area, it may break out and cause disasters in a short period of time. It is one of the world's 100 most harmful alien invasive species announced by the Invasive Species Expert Group of the Species Survival Committee of the International Union for Conservation of Nature. At present, RIFA has invaded and harmed parts of Taiwan, Hong Kong, Guangdong, Guangxi, Fujian, Hunan, and Jiangxi in my country, causing varying degrees of impact on local agricultural production, people's lives, and ecological environment. [0003] Currently, the bait is the main dosage form of the agents used to prevent and control RIFA on the market. Its mechanism of action is to mix ...
