Abstract: Nitromethylene analogues of imidacloprid and divalent and oxabridged heterocyclic neonicotinoid compounds constructed by dialdehydes, preparation methods and uses thereof are disclosed. Compounds represented by formula (A) or (B), their optical isomers or agrochemically acceptable salts are provided. Agrochemical compositions comprising the said compounds, their optical isomers or agrochemically acceptable salts, the uses of the said agrochemical compositions and the preparation methods of the said compounds, their optical isomers or agrochemically acceptable salts are also disclosed. The compounds and their derivatives have high insecticidal activities to several farming and forestry pests including homoptera and lepidoptera pests, such as aphis, fulgorid, whitefly, leafhopper, common thrips, cotton bollworm, cabbage caterpillar, cabbage moth, cotton leafworm and armyworm.

Abstract: The heterocyclic nitrogenous or oxygenous compounds of formula (A), (B), (C) or (D) formed from dialdehydes, their optical isomers, cis- and trans-isomers, or agrochemically acceptable salts, their preparation methods, agrochemical compositions comprising the compounds and the uses thereof are provided. The compounds and their derivatives have high insecticidal activities to several farming and forestry pests including homoptera and lepidoptera pests, such as aphis, fulgorid, whitefly, leafhopper, common thrips, cotton bollworm, cabbage caterpillar, cabbage moth, cotton leafworm, armyworm and so on.

Abstract: The present invention discloses a kind of nitromethylene derivatives as well as their preparation method and their uses. The insecticidal activity tests show that the nitromethylene derivatives of the present invention not only show high insecticidal activities against insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hopper, thrips and white fly and their resistant strains, but also show high insecticidal activities against Lissorhoptrus oryzophilus, carmine spider mite, and they can also be used to prevent sanitary pest, and white ant.
