Coleoptera pests (beetles), Orthoptera nymphs and adults (è—, 蟋蟀, è¼è›„), Hymenoptera larvae and adults. Insecticides with strong stomach toxicity have the most obvious effects on the control of such pests, such as the most commonly used organophosphorus insecticides, some of the stomach-toxic carbamate insecticides, pyrethroid insecticides , Nereistoxin insecticides, benzoylurea insecticides, some insect hormone insecticides, avermectin insecticides, etc. Insecticides with good systemic properties but poor contact and stomach toxicity are usually ineffective against such pests. 2. Internal suction mouthparts pests: These pests suck the young tissues of plants through the mouthparts and suck the juice in the tissues, causing harm, mainly including aphids, spider mites, mites, mites, adults, mosquitoes. Adults, thrips, etc. For such pests, insecticides with good systemic or invasive properties and good stomach toxicity should be selected. Systemic insecticides mainly include organophosphorus insecticides, carbamate insecticides, silkworm toxin insecticides, imidacloprid insecticides, acetamiprid insecticides, and the like. Underground pest control drugs Underground pests mainly include alfalfa (chafer larvae), ground tigers, crickets, crickets, flower buds, and leaf mites. According to the characteristics of life, these pests may live in the soil or on the soil surface at a certain stage, and the damage site is special.

Mix the bait to kill the insects. For special pests In melon crops, if the fruit fly pests have poor control effect, the traits of fruit flies on sweet and sour foods can be considered, and attractants can be made for prevention and treatment. For the drill-bit pests, such as the beetles that are harmful to the stalks, the control method is mainly based on the injection of high-concentration liquid medicine, and the pesticide is selected to have an insecticide having a fumigating effect or a systemic action. For the hibiscus moth, the winged moth, etc., which are responsible for the damage of the current year, it is necessary to control the spraying of the pest eggs during the incubation period. The medicament should preferably be an insecticide having good gastric toxicity, good contact toxicity (and good infiltration).
