An insecticidal and acaricidal composition of the present invention comprises an
active component A and an
active component B, the ratio of weight parts of the
active component A to the active component B being 1:100-100:1. The active component B is selected from one or more of bionic
juvenile hormones,
chitin biosynthesis inhibitors that affect CHS1, type-1
chitin biosynthesis inhibitors,
ecdysone receptor agonists,
nicotinic acetylcholine receptor competitive modulators,
ryanodine receptor modulators,
nicotinic acetylcholine receptor allosteric modulators, glutamate-gated
chloride channel allosteric modulators,
sodium channel modulators,
voltage-dependent
sodium channel blockers, inhibitors, trifluoroethyl
sulfide acaricides and other insecticides and acaricides. The active component A is selected from a compound (I), a compound (II) having the following structures, or stereoisomers thereof. The insecticidal and acaricidal composition of the present invention has the advantages such as obvious synergistic effect and delayed development of
drug resistance, and can be used for controlling a variety of pests.
