There is provided a method of controlling filbertworm capable of reducing the number of release positions without changing a dosage amount per unit area. More specifically, there is provided a method of controlling filbertworm comprising the step of: providing E,E-8,10-dodecadienyl acetate or a composition comprising 80% by weight or more of E,E-8,10-dodecadienyl acetate at 1 to 100 release positions/ha to release the E,E-8,10-dodecadienyl acetate at a release rate of from 0.01 to 5 g/day/ha for mating disruption.

Method of controlling filbertworm

Provided are a sustained release pheromone preparation capable of maintaining a high amount of pheromone release throughout a control period of vine mealybug (VMB) having lavandulyl senecioate (LVSN) as a pheromone substance; and a control method with the preparation. More specifically, provided are a sustained release pheromone preparation comprising a first pheromone substance, and a first container having the first pheromone substance sealed therein and comprising a first polymer membrane made of an ethylene vinyl acetate copolymer containing vinyl acetate units of from 0.5 to 10% by weight, wherein the first pheromone substance is lavandulyl senecioate, which is a pheromone substance of vine mealybug, and the lavandulyl senecioate can be released into the air through the first polymer membrane for 150 days or more; and others.
