1. Dapoxetine: It belongs to the pyridazinone compound, a new type of juvenile hormone analogue, which can inhibit embryogenesis, inhibit insect development and metamorphosis, and is particularly selective for leafhoppers and planthoppers.
2. RH-5849: RH-5849 is moderately toxic and inhibits feeding, accelerates molting and reduces egg laying for scale, sheath and dipteran insect larvae. It is mainly stomach poison, which is effective 2-3 days after application and has a long lasting effect. It is suitable for the prevention and control of vegetable cabbage loopers, Spodoptera litura and Plutella xylostella, rice leaf rollers and armyworms.
3. Tebufenozide: It interferes with the normal growth and development of insects, causing premature and fatal molting of insects. It has special effects on lepidopteran pests and can be used to prevent and control beet armyworms, rice borers, corn borers, apple leaf rollers, pear borers, cabbage loopers and other pests.
4. Methoxyfenozide: It can simulate the molting hormone function of Lepidoptera larvae and promote their early molting. This agent is almost ineffective against insects other than Lepidoptera. It is more active against pests such as tobacco budworm, cotton pests, and diamondback moths, and is suitable for fruit trees, vegetables, corn, grapes and other crops.
5. Chromafenozide: After being ingested by insects, Chromafenozide inhibits insect feeding within a few hours and causes insects to molt early and die. Chromafenozide has strong insecticidal activity against noctuids and other caterpillars, regardless of the period. The main dosage forms are 5% chromafenozide suspension, 5% chromafenozide emulsion and 0.3% chromafenozide powder. It is suitable for preventing and controlling lepidopteran pest larvae on vegetables, tea trees, fruit trees, ornamental plants and rice crops. To prevent and control onion armyworm, spray with 1000 times diluted 5% chromafenozide suspension. To control beet armyworms, spray 5% chromafenozide suspension at a dilution of 1000-2000 times.
6. Tebufenozide: Tebufenozide is very effective against all lepidopteran pests, including beet armyworm, armyworm, rice leaf roller, striped stem borer, stem borer, bean pod borer, corn borer, sugarcane borer, cotton bollworm, peach borer, diamondback moth, leaf miner, leaf roller, etc. It is also effective against coleoptera and dipteran pests. Tebufenozide is an insect growth regulator, and its rapidity and duration of action are greatly improved compared with fenpyroximate in a wide range. Compared with chlorantraniliprole, its rapidity and resistance are improved, and its duration of action is comparable. Compared with chlorantraniliprole, it has better effect on older insects. Tebufenozide can be used to control pests that have developed resistance to chlorantraniliprole.
7. Pyriproxyfen: Pyriproxyfen is a phenyl ether insect growth regulator that disrupts insect growth. It is a new type of insecticide that is a juvenile hormone analogue. It has systemic transfer activity, low toxicity, long lasting effect, safety to crops, low toxicity to fish, and little impact on the ecological environment. It has good control effects on pear psylla, whitefly, scale insects, diamondback moth, beet armyworm, armyworm, pear yellow psylla, thrips, etc.
8. Cyromazine: Cyromazine is a low-toxic insecticide of the insect growth regulator class. It has very strong selectivity and is mainly active against Diptera insects. Its mechanism of action is to cause morphological deformation of Diptera insect larvae and pupae, and incomplete or inhibited adult emergence. The drug has contact and stomach poison effects, strong systemic conductivity, a long lasting effect, but a slow action rate. Cyromazine can be mixed with abamectin, chlorpyrifos, and insecticide to produce compound insecticides. Cyromazine is suitable for a variety of fruits and vegetables, and has a good insecticidal effect on "fly" pests. At present, it is mainly used in the production of fruits and vegetables to prevent and control: American leafminers, South American leafminers, bean stem black leafminers, onion leafminers, trifoliate leafminers and other leafminers in various fruits, solanaceous fruits, beans and various leafy vegetables, and root maggots (leek late eye fungus mosquitoes) in leeks, onions, and garlic.
