信息素是一种在昆虫体内产生、分泌排出体外,而对其它个体表现强烈的,特有的生理机能的活性物质。它具有生物活性高、专一性强和无公害等特点。人工合成性信息素(简称性诱剂)的应用途径如下:(1)用于测报。性诱剂用于害虫测报简便易行,且只引来单一目标害虫,较灯光诱杀具有准确、省时、省力的优点。又不受电源限制,可以任意放在适当位置。另外,对某些趋光性弱和完全没有趋光性的害虫也可进行准确测报。(2)进行诱杀。采用大量陷井接连诱杀雄虫,使雌虫不能产卵或产的是未受精卵,从而达得减轻危害目的。(3)迷向防治。即把一
Pheromone is a kind of active substance which is produced in insect body, excreted and excreted, while it exerts a strong and unique physiological function to other individuals. It has high biological activity, specificity and pollution-free features. Synthetic pheromone (referred to as sex attractant) applications are as follows: (1) for the newspaper. Sex lure is simple and easy for pests to measure and report, and it only leads to a single target pest, which has the advantages of accuracy, time saving and labor saving compared with light trapping. Not subject to power restrictions, you can arbitrarily put in place. In addition, for some phototaxis weak and no phototropism of pests can also be accurately measured. (2) Trapping and killing. Using a large number of trap trap trapping males, so that females can not lay eggs or produce unfertilized eggs, so as to achieve the purpose of reducing the harm. (3) to the prevention and treatment. That one
