甘蔗二点螟(Chilo infuscatellaSnellen)是我国分布最广、为害最严重的甘蔗害虫,在北方为害谷子、粟和高梁,称粟灰螟。二点螟为害甘蔗苗期造成枯心,减少有效茎,为害中后期造成螟节害,因而降低了蔗糖份,同时也增加风折茎,引起减产。目前,控制此虫的猖獗,主要是利用杀虫剂,但是,由于杀虫剂的残留量及对环境污染问题无法解决。为了探索新的防治手段,从1975年开始,我国南方对其性信息素进行研究,但由于不能从雌蛾腹尖稳定的提取出性信息素,从而无法提供合成物,因此给应用带来一定困难。
Sugarcane borer (Chilo infuscatellaSnellen) is the most widely distributed in China, the most serious damage of sugar cane pests in the north for the damage of millet, millet and sorghum, called the corn borer. The damage of sugarcane at the seedling stage by the C. punctatus causes the dead heart, reduces the effective stem, and causes damage to the stem at the mid-late stage of the damage, thus reducing the sucrose content and increasing the wind-folding stem, causing the yield reduction. At present, the rampant control of this pest is mainly the use of pesticides, however, due to pesticide residues and environmental pollution problems can not be solved. In order to explore new means of prevention and treatment, from the beginning of 1975, the sex pheromones in southern China were studied. However, since the pheromone can not be extracted steadily from the abdominal muscles of female moths, difficult.
