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.

A system and method of application and dispersion of mating disruption materials or other materials to control insect population. Disclosed is an apparatus designed to be carried by a ground vehicle, or aerial means, which implements a method of insect population control. The apparatus features one or more removable vacuum reservoirs that contain a mating disruption formulation in cylinders or bags. The vacuum bags or vacuum cylinders are seated upon one or more computer controlled peristaltic pump heads, housed in a insulated controlled environment box, that pump the material to one or more forming nozzles. Once formed the material drops into the wind stream of one or more tangential vortex type fans. Maintaining its size and shape, the mating disruption material will travel through the air field, and become attached in the trees where it will omit a flume of sex pheromones that disrupt the ability of the male insect in finding the female insect, breaking the mating cycle of the insect population. Thus serving to decrease the population by capitalizing on a weakness in the reproductive cycle of the citrus leaf miner or other insect.

The invention discloses a conopomorpha sinensis bradley prevention and control composition including the following components by weight: 20-80 parts of trans-4, 6-cis-10-hexadecyl triene acetate, 5-35 parts of cis-9-hexadecenol acetate, 5-35 parts of trans-9-hexadecenol acetate and 10 parts of n-dodecyl alcohol. The conopomorpha sinensis bradley prevention and control composition is used for disturbing mating behavior of imago so as to reducing the amount of the larva. The conopomorpha sinensis bradley prevention and control composition is simple in formula and has good mating disruption effect, shows excellent control effect and greatly reduces the base number of the larva in fields during use in fruit tree pest insect conopomorpha sinensis bradley prevention and control, and has a huge advantage in the conopomorpha sinensis bradley prevention and control.
