The anti-controlling agent of a kind of novel red fire ant, comprise former medicine, the solvent of former medicine, propellant, described former medicine is the mixture of efficient fluorine Cypermethrin and Diacloden,
Described preparation is obtained by following preparation method: be dissolved in solvent by former medicine, adds one and is equipped with in the tank of valve, and in tank, adds the obtained insecticidal aerosol tank of propellant under stress by this valve;
Described former medicine weight accounts for 0.005% ~ 1% of composition total weight in insecticidal aerosol tank.
Further, the weight of described efficient fluorine Cypermethrin accounts for 0.1 ~ 0.5% of aerosol gross weight.
Further, the weight of described Diacloden accounts for 0.01 ~ 0.1% of aerosol gross weight.
Further, the weight of described propellant accounts for 50 ~ 70% of composition total weight in insecticidal aerosol tank.
In addition, the solvent of former medicine can use arbitrary solvent that can dissolve efficient fluorine Cypermethrin or Diacloden, as water, alcohols, aliphatic hydrocarbon, aromatic hydrocarbon, halogenated hydrocarbons, ester class, ethers, ketone, acetonitrile etc.The concrete selection of solvent is the common practise of those skilled in the art.
Propellant is the indispensable component of insect aerosol, and generally elect liquefied petroleum gas, the third butane, dimethyl ether, compressed air etc. as, the concrete selection of propellant is the common practise of those skilled in the art.
The using method of red fire ant aerosol of the present invention is, alarm a little ant nest (as with branch ant nest surface light insert several under), after the red fire ant individuality of sufficient amount of gushing out, the by-pass valve control of aerosol tank is aimed at red fire ant individuality press, under the pressure of propellant is used, produce high velocity air, tank is included the liquid aerosol dispersion of active ingredient and the gasification of propellant, thus make the mist droplet containing former medicine be covered with red fire ant body surface, even enter ant nest inside along ant road.According to the habit mutually cleaning health between red fire ant individuality, make former medicine conduct to full nest red fire ant, thus thoroughly kill full nest red fire ant.
The present invention has following beneficial effect:
The present invention is a kind of aerosol preventing and treating red fire ant, compare existing bait formulation and pulvis tool has the following advantages: (1) is by the impact of temperature and surface humidity, therefore also Solenopsis invicta can be carried out in the winter being not suitable for using bait formulation, because be exactly the red fire ant amount reproduction phase to spring, carry out Solenopsis invicta winter and be conducive to controlling red fire ant harm with less manpower and less medicine.(2) the present invention is aerosol, compares pulvis, and the mist droplet of aerosol ejection is more easily attached to red fire ant body surface, and adhesion amount is larger, and therefore drug effect is better.(3) aerosol is owing to becoming aerosol state, can enter ant nest inside, make to award medicine individuality more, reach better control efficiency along ant road.(4) the former medicine of the present invention uses betacyfluthrin and Thiamethoxam compound, betacyfluthrin is a kind of pyrethroid insecticides of synthesis, the conduction at insect neural axon position can be suppressed, Diacloden belongs to nicotinic insecticide, its mechanism of action is alternative suppression insect nerve system nicotinic acetylcholine esterase acceptor, and then block the normal conduction of insect CNS, cause insect benumb and dead, both are without cross resistance, the mechanism of action is different, and betacyfluthrin plays the time comparatively long 3-5 days of Diacloden of drug effect, both are composite makes the performance of drug effect of the present invention have a time difference, more thorough to the killing effect of ant nest.
