Provided are a sustained releaser of sex pheromone substances and a method for controlling insect pest by using the releaser, each enabling to control the simultaneous release of a mixture of sex pheromone substances having different chemical structures of one insect pest or a mixture of sex pheromone substances of insect pests, and each enabling to release the sex pheromone substances at a fixed rate or greater during the infestation period or periods of the respective insect pest or pests. More specifically, provided is a sustained releaser of sex pheromone substances comprising one or more first sex pheromone substances selected from linear aliphatic aldehyde having 10 to 18 carbon atoms, one or more second sex pheromone substances selected from aldehyde-free aliphatic derivatives having 7 to 20 carbon atoms, and first and second chambers each made of polymer material, wherein all of the first sex pheromone substances or all of the first sex pheromone substances and some of the second sex pheromone substances are enclosed in the first chamber and the remainder of the sex pheromone substances is enclosed in the second chamber.
本发明提供了一种性信息素物质持续释放剂和一种使用该释放剂控制害虫的方法,每种释放剂都能控制一种害虫或一种害虫的性信息素物质混合物具有不同化学结构的性信息素物质的同时释放,并且每种释放剂都能在相应害虫的一种或多种侵扰期间以固定或更大的速率释放性信息素物质。更具体地说,本发明提供了一种性信息素物质持续释放器,包括一种或多种选自具有 10 至 18 个碳原子的线性脂族醛的第一性信息素物质、一种或多种选自具有 7 至 20 个碳原子的无醛脂族衍生物的第二性信息素物质、以及各自由聚合物材料制成的第一和第二腔室,其中所有第一性信息素物质或所有第一性信息素物质和部分第二性信息素物质被封闭在第一腔室中,其余性信息素物质被封闭在第二腔室中。
