Description

A kind of fire ant bait agent and using method thereof

The present invention be directed to original application is application number 200810198399.3, and on September 10 2008 applying date, name is called dividing an application of " a kind of fire ant bait agent and using method thereof ".

Technical field

The present invention relates to a kind of red fire ant medicament and using method thereof killed.

Background technology

Red fire ant ( Solenopsis invictaBuren; Red imported fire ant; RIFA) be the important quarantine insect of newly invading China in recent years, it is one of Alien invasive species of the tool harmfulness in 100 kinds in the world that announces of the invasive species expert group of the species existence committee under the World Conservation Union.Be used for the medicine of prevention and control red fire ant with domestic existing several in the world at present, formulation mostly is graininess bait formulation and pulvis, a kind of graininess fire ant bait agent of announcing of Chinese patent application 200510121365.0 for example, by 0.01%～0.03% multiple killing teichomycin, 99.97%～99.99% plant protein hydrolysate or animal hydrolyzed protein or higher fatty acid or sugared the composition, its application method is got food for bait formulation is spread fertilizer over the fields around anthill for red fire ant; And the Powdered fire ant bait agent that Chinese patent application 200610123411.5 is announced, it is formed component and comprises one or more mixture 0.001%～1% in fluorine worm nitrile, Avermectin, pleocidin, Hydramethylnon Bait, the pyriproxyfen, cracker meal 88%～99.899%, the nanoscale powder 0.1%～10% of one or more in silica, diatomite, tricalcium phosphate, zeolite powder, titanium dioxide, aluminium oxide, zircon, the feldspar and potassium sorbate 0～1%, application process is for discharging bait formulation on the body of the red fire ant that pours out; And Chinese invention patent 200510034579.4 disclosed a kind of medicament and methods of killing red fire ant, formulation is pulvis, constituent has fluorine worm nitrile 0.005%～0.1%, starch 89～91.5%, sugar 3～4%, fat 3～5%, spices 0.05～0.1%, iron oxide red powder 1～2%, its application method is first disturbance anthill, after red fire ant pours out, medicament powder is sprayed on aperture and red fire ant.The common feature of the red fire ant medicament that relates in these documents is, the component that its mass percent accounts for lion's share is edible material mostly, just lure red fire ant to get the material of food, in 200510121365.0, account for 99.97%～99.99% plant protein hydrolysate or animal hydrolyzed protein or higher fatty acid or sugar, 200610123411.5 in account for 88%～99.899% cracker meal, 200510034579.4 in account for 89～91.5% starch and account for 3～5% fat, but along with rising steadily of provision price, adopt these materials will certainly make its manufacturing cost more and more higher in the red fire ant medicament.

Summary of the invention

Technical problem to be solved by this invention provides a kind of fire ant bait agent, and this bait formulation is liquid bait formulation, and is cheap for manufacturing cost.

For solving the problems of the technologies described above, the composition proposal of this fire ant bait agent is:

By percentage to the quality, contain

(1) 0.0025%～10% multiple killing teichomycin;

(2) 15%～25% carbohydrate;

(3) 10%～25% thickener;

(4) 0.005%～6% solvent;

(5) 0.01%～0.03% preservatives;

(6) surplus is water.

In the said components, carbohydrate is white granulated sugar or glucose; Thickener is gum Arabic or starch or cellulose, and preservative is Sodium Benzoate or dehydro sodium acetate.

Another technical problem to be solved by this invention provides a kind of using method of fire ant bait agent, and this method is simple and easy to usefulness, the dispenser personnel is injured little, and the temperature during to dispenser is not strict with.

For solving the problems of the technologies described above, the using method of fire ant bait agent is:

(1) get an amount of fire ant bait agent and place the container with nozzle, thin up is to the concentration that needs;

(2) first employing instrument disturbance ant nest makes red fire ant pour out;

(3) fire ant bait agent is sprayed at rapidly on the red fire ant body surface of gushing out and the anthill surrounding soil on.

The present invention has following remarkable result compared to existing technology:

Fire ant bait agent provided by the present invention, the active insecticidal components of chronic stomach toxicity is soluble in water, add red fire ant simultaneously and get food stimulation component carbohydrate and thickener, the fire ant bait agent of this prescription is sprayed on the body surface of red fire ant, treat that it gets back in the nest, characteristics according to the habit of licking the cleaning health between the red fire ant individuality mutually and happiness sugar class can conduct to toxicity whole ant nest.The soup that is not sprayed onto the red fire ant body surface and is attached to the anthill surface also can be owing to its viscosity and sugariness, is inhaled by red fire ant is fair, by the habit of feeding mutually between the red fire ant individuality toxicity is conducted to whole ant nest.

What the fire ant bait agent of this prescription accounted for large percentage is water, only contains a spot of red fire ant and lures composition---carbohydrate, do not contain Edible materials such as cracker meal, fat, and can reduce raw-material cost greatly.This fire ant bait agent, production technology is simple, is convenient to transportation, is fit to spray on a large scale, and environmental pollution is little, the dispenser personnel is injured little, and the temperature during to dispenser is not strict with.

The using method of fire ant bait agent of the present invention, compare with the using method of existing solenopsis invicta buren control preparation, its advantage is that spraying tool is sprayer, can spray at a distance, may stick to when having avoided bait formulation and pulvis dispenser on the human body and the dispenser personnel are damaged.

Embodiment

The method that the present invention is intended to protect a kind of fire ant bait agent of liquid state and sprays dispenser.The physical form of this fire ant bait agent is liquid, is different from the medicament of existing similar graininess or powdery.The active component of this fire ant bait agent is multiple killing teichomycin, the active insecticidal components of the chronic stomach toxicity of this class is soluble in water, add red fire ant simultaneously and get food stimulation component carbohydrate, thickener and preservative, adding thickener can increase the toughness of liquid bait formulation, make liquid bait formulation more be attached to red fire ant body surface and stick on the soil on anthill surface, thickener can be selected gum Arabic, starch, cellulose, and carbohydrate can be selected white granulated sugar or glucose; Preservative can be selected Sodium Benzoate or dehydro sodium acetate.

Below by specific embodiment the compound method of the liquid bait formulation of this red fire ant is described, these methods are to illustrate of the present invention, are not limitations of the present invention.

Embodiment 1, is active insecticidal components with multiple killing teichomycin (spinosad):

Each composition and mass percentage content are:

Composition	Shared mass percent
		Multiple killing teichomycin	0.1％～0.3％
Isopropyl alcohol	0.2％～2％
		Glucose	15％～25％
Gum Arabic	15％～25％
		Water	49.67％～69.69％
Sodium Benzoate	0.01％～0.03％

The mechanism of action of multiple killing teichomycin is by activating nicoting type acetylcholinergic receptor (nAChR), makes the depolarising of normal insect nerve cell, also can make the nerve cell hyperpolarization by suppressing gamma-aminobutyric acid receptor (GABAR).Have efficient, low toxicity, strong, the environmentally safe characteristics of selectivity, consumption is extremely low in the liquid bait formulation of red fire ant, but control efficiency is remarkable.

During preparation, by percentage to the quality, get 25 parts of gum Arabics, 20 portions of white granulated sugars are dissolved in 55 parts of water, add thermal agitation and cooling, and 0.1 part of multiple killing teichomycin dissolves with 0.6 part of isopropyl alcohol, adds wherein, and the Sodium Benzoate that adds 0.03 part had more both got fire ant bait agent.During use, bait formulation is poured in the sprayer, 5 times of thin ups can use.

After the medication 3 days, the worker ant rate of going down reaches more than 70%, and full nest red fire ant can be killed after a week, the back worker ant rate of going down can reach 95%, one month.
