MATING DISRUPTION METHOD USING ACETATE-CONTAINING MATING DISRUPTANT

摘要

Provided is a mating disruption method capable of bringing a stable and effective mating disruption result. Specifically provided is a mating disruption method comprising a step of starting to apply a mating disruptant after mating and oviposition of imagoes of the first generation of an insect pest are substantially over and before imagoes of the second generation of the insect pest emerge, the mating disruptant targeting at least one kind of insect pest which contains one or more kinds of acetates as a natural sex pheromone, the insect pest being selected from the group consisting of tortricid ( Leafroller ), armyworm ( Spodoptera ), Sesiidae (Synanthedon), pink bollworm ( Pectinophoragossypiella : PBW), European grapevine moth ( Lobesia botrana : EGVM), tomato pinworm ( Keiferia lycopersicella : TPW), light brown apple moth ( Epiphyes postvittana ), Grapholita dimorpha Komai ( Grapholita dimorpha ), apple leafminer ( Phyllonorycter ringoniella ), tomato leafminer ( Tuta absoluta ) and European goat moth ( Cossus cossu s), all of which are substantially free of alcohol derived from the acetates as well as oriental fruit moth ( Grapholitha molesta : OFM) and omnivorous leafroller ( Platynota stultana ), both of which contain 1.5% by weight or less of alcohol or alcohols derived from the acetates; and the mating disruptant comprising the acetates and the alcohol or alcohols derived from the acetates wherein each amount of the alcohol or alcohols is 1.5 to 10% by weight relatively to each amount of the acetates.
