在毛主席革命路线指引下,随着我国农业科学实验群众运动的蓬勃发展,南方九省(区)对甘蔗螟虫性外激素的试验研究已取得了可喜的进展。我们知道,对任何一种昆虫性激素的应用研究,一般都是要经过活虫田间生物测定—→粗提天然性引诱物—→分离、提纯、鉴定、合成这样三个大步骤。目前,我国对甘蔗螟虫性外激素的研究,大多数省(区)都正在进入第二步,处于攻坚阶段中。据报导,一种昆虫在用活蛾作诱捕时比粗提物作生测时有效 Under the guidance of Chairman Mao’s revolutionary line, with the vigorous development of the masses of agricultural science experiments in our country, the experimental research on the sex hormone of sugarcane borers in nine southern provinces (regions) has made gratifying progress. We know that the application of any kind of insects sex hormones, are generally go through live biological determination of the field - → crude natural decoy - → separation, purification, identification, synthesis of these three major steps. At present, most of the provinces (autonomous regions) in China are now entering the second stage in the study of sex hormone of sugarcane borers, which is in the stage of tackling crucial problems. It has been reported that an insect is more effective than raw extract for live measurement when using live moth for trapping
