Problems solved by technology

[0005] Studies have shown that pests are not easy to develop resistance to botanical pesticides, and there are no reports of resistance to botanical pesticides in domestic academic journals
However, due to the characteristics of easy photolysis and oxidation of plant extracts, poor stability and short duration, its use is subject to many restrictions. Currently, only a few plant extracts on the market are used for pest control. For example, azadirachtin, matrine, rotenone, etc., and the dosage forms are emulsifiable concentrate, water, powder
Due to technical reasons, no botanical medicament has been processed into a bait, let alone a botanical bait for killing red imported fire ants.

Embodiment 1

[0018] In the present embodiment, the insecticidal active ingredient is formed by mixing two equal parts mass ratios of matrine and phasicine. According to 100 parts by mass fraction, 4 parts of the mixture of matrine and phasicine are taken. The microcapsule embedding agent processed from corn starch takes 30 parts, the mixture of sugar and fat is used as the food-inducing substance, and the extraction is 65.8 points, and the preservative sodium sorbate is 0.2 points.

[0019] The specific preparation method is as follows:

[0020] a: Dissolve 4 parts of the mixture of the effective active ingredients matrine and picroderm in acetone (or other volatile organic solvents), add microcapsule embedding agent, and the microcapsule embedding agent adopts modified starch The ester-modified starch is then stirred evenly with a mixer, and the organic solvent is completely evaporated to make plant extract microcapsules.

[0021] b: The prepared microcapsules are uniformly mixed with th...

Embodiment 2

[0033] In the present example, the insecticidal active ingredient is mixed by three components of argentina, toxin, and picerine according to a mass ratio of 1:1:2. Take 2.9 parts of the mixture of acetrine and phaeloperidin, take 26 parts of the ester modified starch microcapsule embedding agent processed from cornstarch, take the mixture of spices and fish protein as the food-attracting substance, extract 71 parts, preservative Sodium sorbate is 0.1 part.

[0034] The microcapsule-containing bait prepared according to the above ratio also has a good control effect on the red fire ant nest. Moreover, this kind of bait will not cause the RIFA to develop drug resistance, and will not produce toxic effects on humans and the environment. It is a safe and environmentally friendly bait for preventing and controlling RIFA.

Abstract

The invention relates to the technical field of red fire ant drugs, in particular to a bait type red fire ant drug. Effective ingredients of the bait by weight percentage are 0.01 percent-5 percent of insecticidal active ingredient extracted from insecticidal plants, and teh active ingredient can be one or more of rotenone, matrine, strophanthus divaricatus glycoside, coniine, celangulin and veratrine, 4 percent-40 percent of edible micro-capsule embedding medium, 54.7 percent to 95.89 percent of eating action tempting material that is one or the mixture of animal protein, vegetable protein, glucide, grease and spice and 0.1 percent -0.3 percent of potassium sorbate or sodium sorbate as preservative. The effective ingredients of the bait are extracted from natural plants, thus being degraded in environment timely, and the oxygenolysis speed of the bait can be controlled by introducing controlled release technology. The bait can kill all red fire ants in a nest by alluring ergates of red fire ants to carry the bait to the nest, taking advantage of the habit of cross feeding one to another and passing toxicity to queen ant and other individuals.

Description

technical field [0001] The invention relates to the technical field of red imported fire ant drugs, in particular to a safe and environment-friendly bait type red imported fire ant drug. Background technique [0002] The red fire ant (Solenopsis invicta Buren, Red imported fire ant, RIFA) belongs to Hymenopetera (Hymenopetera), Formicidae (Formicidae), Leaf-cutting Ant Subfamily (Myrmicinae) Fire Ant (Solenopsis), is a species that belongs to the International Union for Conservation of Nature. One of the world's 100 most harmful alien invasive species announced by the Committee's Invasive Species Expert Group. RIFA has a major impact on agricultural production, ecological environment, public safety and social economy, and is listed as an important quarantine object by many countries. [0003] RIFA was first discovered in the Wuchuan area of ​​mainland China in early 2005, and then found in most areas of Guangdong Province, Guangxi, Fujian, and parts of Hunan. RIFA preventi...
