This invention discloses an insecticidal composition for controlling Lepidoptera,
Hemiptera, and Thysanoptera pests and its application. The active ingredients of the insecticidal composition are HNPC-A18237 and
abamectin, with a
mass ratio of HNPC-A18237 to
abamectin of 5–1:1–5. This insecticidal composition can be applied to control Lepidoptera,
Hemiptera, and Thysanoptera pests. It exhibits a significant synergistic effect, superior to single active ingredients in both rapid and sustained action. Simultaneously, it reduces the risk of pest resistance to
abamectin, broadens the application range of HNPC-A18237, and reduces
pesticide dosage and cost, thus benefiting
environmental protection. It is highly effective in controlling Lepidoptera,
Hemiptera, and Thysanoptera pests in vegetables, rice, fruit trees, and flowering crops.
