【摘要】 联苯·噻虫胺是一种新型复合型杀虫剂，可用于防治棉铃虫等20余种害虫。本文探讨了该悬浮剂的特性与组成、作用机制、使用效果及其在农业领域的应用技术与实践，并对其研究进行展望。联苯·噻虫胺悬浮剂由联苯菊酯和噻虫胺两种成分复配而成，具有快速杀虫与长效保护的双重特性；作用机制包括触杀、胃毒和内吸传导作用，既能通过直接接触害虫身体表面，通过溶解害虫外骨骼表面的蜡质层穿透进入或通过微小孔隙进入害虫体内，又能通过害虫的口器和消化道进入虫体，还能够通过害虫刺吸取食含有药剂的植物茎叶间接进入虫体，使害虫中毒死亡；使用效果上，该药剂具有杀虫谱广、速效与持效、低毒、安全环保等优势，其还具有良好的环境与生态安全性，对作物生长安全、能与其他化学药剂兼容、对水生生物和有益生物的影响较小，在土壤中可随时间推移降解为无害物质；前期该药剂已被用于防治粮食作物、果蔬等多种作物上的蚜虫、地老虎、蓟马、梨木虱等害虫，其可采用喷雾、滴灌和冲施等方式进行施用。未来，将进一步优化该药剂的配方，开发更高效、稳定的剂型，并进行环境友好性及精准施药技术研究。综上，联苯·噻虫胺悬浮剂能减少化学农药的施用量，延缓害虫抗药性发展，延长农药使用寿命，应用前景广阔。更多还原

【Abstract】 Bifenthrin·clothianidin is a new type of compound insecticide that can be used to control more than 20 pests such as Helicoverpa armigera. This study explores the properties, composition, action mechanism, and application effects of this suspension concentrate, as well as its application technologies and practices in the agricultural field, and prospects for future research. The suspension concentrate is formulated by combining two active ingredients, bifenthrin and clothianidin, with dual characteristics of rapid insecticidal activity and long-term protection. Its action mechanism includes contact toxicity, stomach toxicity, and systemic translocation: it can penetrate into the insect body either by directly contacting the insect surface(dissolving the waxy layer on the exoskeleton or through microscopic pores), enter via the insect’s mouthparts and digestive tract, or indirectly infiltrate the insect body when the pest engages in piercingsucking feeding on plant stems and leaves treated with the insecticide, ultimately leading to insect death by poisoning. In terms of application effects, this insecticide offers advantages such as a broad insecticidal spectrum, quick-acting and long-lasting efficacy, low toxicity, safety, and environmental friendliness. It also exhibits excellent environmental and ecological safety: it is safe for crop growth, compatible with other chemical agents, has minimal impacts on aquatic organisms and beneficial organisms, and can degrade into harmless substances in soil over time. Previously, this insecticide has been used to control pests such as aphids, cutworms, thrips, and pear psylla on various crops including food crops, fruits, and vegetables, and can be applied through methods such as spraying, drip irrigation, and drenching. In the future, efforts will be made to further optimize its formulation, develop more efficient and stable dosage forms, and conduct research on environmental friendliness and precise application technologies. In summary, bifenthrin·clothianidin suspension concentrate can reduce the application rate of chemical pesticides, delay the development of pest resistance, and extend the service life of pesticides, thereby boasting broad application prospects.更多还原
