The acetamiprid is also called Mobian, is a novel pesticide, belongs to nitromethylene heterocyclic compounds, acts on a nicotine acetylcholine receptor at a synapse part of an insect nervous system, interferes with stimulation conduction of the insect nervous system, causes block of a nervous system channel, causes accumulation of neurotransmitter acetylcholine at the synapse part, and accordingly causes paralysis of insects and death. Has the functions of contact poisoning and stomach poisoning, and has strong osmosis, good quick action and long lasting period. The acetamiprid can be used for preventing and controlling pests of rice, vegetables, fruit trees, tea trees, such as aphids, plant hoppers, thrips, lepidoptera and the like. The imidacloprid has the same series with imidacloprid, but the insecticidal spectrum of the imidacloprid is wider than that of imidacloprid, and the imidacloprid mainly has better control effect on aphids on cucumbers, apples, oranges and tobaccos. The acetamiprid has unique action mechanism and thus high effect on pests with pesticide resistance to organophosphorus, carbamate, pyrethroid and other pesticide varieties.

Diatomite is sedimentary rock with wide distribution, is easy to grind into powder and has strong water absorption. The diatomite can kill pests because each fine particle of the diatomite powder has a very sharp edge, and when the diatomite powder is contacted with pests, the diatomite powder can pierce the body surfaces of the pests and even enter the bodies of the pests, so that the systems of respiration, digestion, reproduction, movement and the like of the pests can be disordered, and the diatomite powder can absorb water which is 3-4 times of the weight of the diatomite powder, so that the body fluid of the pests is sharply reduced, and the pests die after losing more than 10 percent of the body fluid.

It should be noted that, the acetamiprid is used for a long time, the drug resistance of the pests to the acetamiprid is continuously enhanced along with the increase of the service life of the drug, and at the moment, the dosage of the drug and the number of times of application of the drug are continuously increased to achieve the effect of killing the pests, so that the cost is increased, the pollution to the environment is increased, the acetamiprid and diatomite are used in combination, the drug resistance of the pests to the acetamiprid is reduced, the better insecticidal effect is achieved, the dosage is reduced, the insecticidal cost is reduced, the pesticide residue is reduced, and the environment is protected well.
