信息素是一种昆虫分泌的化学气味,作为它们传递信息的一部分。现已经分离和人工合成这些具有种特殊性的气味并大规模用来防治有重要经济意义的害虫。用信息素监控农作物害虫已有10多年的历史,但应用信息素监控储粮害虫,则还是最近几年的事。据最近的的资料表明,在储粮害虫中有二种基本类型的信息素,一类是性信息素,常由雌虫产生,虽然其量极少,但能吸引雄虫。另一类是集合信息素,一般由雄虫产生,可以吸引雌虫和雄虫。集合信息素是食物存在的一种信号,同时也可导致相遇昆虫的交配。 Pheromones are chemical secretions secreted by insects as part of their message. These peculiar smells have been isolated and artificially synthesized and used on a large scale to control pests of great economic importance. It has been more than 10 years since pheromone was used to monitor pests in crops. However, the monitoring of stored pests using pheromones is still a matter of recent years. According to recent sources, there are two basic types of pheromones in stored grain pests, one is sex pheromone, often produced by females, which, although in very small quantities, can attract males. The other is a collection of pheromones, usually produced by males, can attract females and males. The collection pheromone is a signal that food exists and can also result in the mating of the encounter insects.
