吡蚜酮pymetrozine是瑞士原诺华公司1988年开发的,属于吡啶类或三嗪酮类杀虫剂。吡蚜酮可以用于蔬菜、小麦、水稻、棉花、果树等多种作物,几乎对所有类型的刺吸口器害虫,如甘蓝蚜、棉蚜、麦蚜、桃蚜、小绿斑叶蝉、褐飞虱、灰飞虱、白背飞虱、甘薯粉虱及温室粉虱等都有防控作用。
吡蚜酮主要特点是有内吸性,抑制昆虫取食,但无击倒活性,对刺吸式口器害虫高效。吡蚜酮对水稻、蔬菜、棉花、小麦和果树等作物的蚜虫、飞虱、叶蝉、粉虱等具有很高的防效。该药剂对同翅目害虫选择性极佳,对蚜虫的选择性优于目前最好的抗蚜剂——抗蚜威,还具有良好的内吸性。Pymetrozine 是同翅类的饲养抑制剂,可防止蚜虫种 Mysus persicae (Sulzer) 传播花椰菜马铃薯毛霉病毒。Homoptera
吡蚜酮对蜜蜂、鱼类等水生生物、家蚕有毒,施药期间应避免对周围蜂群的影响,蜜源作物花期、蚕室和桑园附近禁用。养育稻田禁用,远离水产养殖区施药,禁止在河塘等水体中清洗施药器具。
Pymetrozine, a fast-acting and selective inhibitor of aphid feeding. In-situ studies with electronic monitoring of feeding behaviour. Pymetrozine, a pyridine azomethine compound, represents a novel insecticide with a selective activity against homopteran insects. It acts in a unique way: aphids are not knocked down on contact but seem to die of starvation. This implies an effect of Pymetrozine on feeding behaviour. The aim of the present work is to elucidate how and at which step Pymetrozine interferes with the complex mechanisms underlying phloem feeding. The effect of Pymetrozine, applied in various ways, on different phases of stylet penetration and feeding activity of individual aphids is studied using the Electrical Penetration Graph technique (EPG). Initial choice experiments indicated that Pymetrozine does not have a deterrent or antifeedant action. Topical application (150 ng/mg fresh weight) inhibits stylet insertion into the plant. When injected, less than 30 ng/mg is sufficient to produce the same effect. When Pymetrozine is systemically applied via plant spraying or root uptake, aphids started feeding normally. After some time, however, they withdrew their stylets from the phloem and walked around with unaffected locomotion. At low doses aphids eventually recovered and resumed feeding. High doses, however, irreversibly disrupted feeding and prevented stylet reinsertion. Aphid motility is not affected up to an estimated haemolymph concentration of 1 mM Pymetrozine. Aphids which eventually stopped feeding on Pymetrozine-treated plants showed EPGs with distorted salivation/ingestion patterns.
吡蚜酮低毒,对天敌影响小,仅作用于刺吸口器害虫。该化合物对皮肤和眼睛均无刺激,且无致突变性。对哺乳动物毒性很低,对于鸟类、鱼类、蜜蜂等也有很好的安全性。
