昆虫生长调节剂的种类和作用机理摘要：昆虫生长调节剂是通过干扰昆虫正常生长发育，致使昆虫个体活动能力下降或死亡，从而导致种群灭绝的一类特异性杀虫剂。

本文综合介绍昆虫生长调节剂的发展概况，详述保幼激素类似物、蜕皮激素类似物、几丁质合成抑制种类及其开发应用研究情况，并对其毒理作用机制进行了论述，目前研究表明该类药剂对害虫具高效，对环境污染小，保护害虫天敌，具有明显的选择活性。

昆虫生长调节剂虽然发展缓慢，但是应用前景广阔。

关键词：昆虫生长调节剂；毒理机制；研究应用1. 昆虫生长调节剂的发展概况昆虫生长调节剂(Insect Growth Regulators)是通过抑制昆虫生理发育，如抑制蜕皮、抑制新表皮形成、抑制取食等导致害虫死亡的一类药剂。

1967年威廉姆斯提出以保幼激素(JH)及蜕皮激素(MH)为主的昆虫生长调节剂作为第三代杀虫剂。

1985年赵善欢认为昆虫生长调节剂应包括保幼激素(JH)、蜕皮激素(MH)及其类似物、抗保幼激素(JH)、几丁质合成抑制剂、植物源次生物的拒食剂、昆虫源信息素、引诱剂等干扰害虫行为及抑制生长发育特异性作用的缓效型“软农药”，从而拓宽了昆虫生长调节剂的范畴。

由于应用此类药剂有利于无公害绿色食品生产，符合人们保护生态要求，曾一度广泛受到人们的关注，并进行开发研究。

后因第二代有机合成杀虫剂(有机磷类、氨基甲酸酯类和拟除虫菊酯类杀虫剂)能高效、经济地防治害虫，致使昆虫生长调节剂步入低谷。

但随着“农药万能论”思潮的蔓延，“3R”不断加剧，人们对农药的概念又从“杀生物剂”转向寻找“生物合理农药”或“环保和谐农药”的新型杀虫剂，昆虫生长调节剂重新得到重视。

由于其作用机理不同于以往作用于神经系统的传统杀虫剂，毒性低、污染少、对天敌和有益生物影响小，有助于可持续农业的发展，有利于无公害绿色食品生产，有益于人类健康，因此被誉为“第三代农药”、“二十一世纪的农药”、“非杀生性杀虫剂”、“生物调节剂” ,“特异性昆虫控制剂”，由于它们符合人类保护生态环境的总目标，迎合各国政府和各阶层人民所关注的农药污染的解决途径这一热点，成为全球农药研究与开发的一个重点领域。

这种方法具有反应条件严格、产物纯度高等优点，是目前应用较广泛的生产方式之一。

2. 合成法的优缺点在使用合成法制备GlNAc时，常见的优点是反应条件控制容易、产物纯度高，适用于大规模工业生产。

然而，合成法也存在着原料成本高、环境影响大等缺点，制约了其在可持续发展中的应用。

三、N-乙酰氨基葡萄糖的发酵法1. 发酵法的原理发酵法是指利用微生物生物转化的方式制备GlNAc，其原理是将适合的原料通过发酵反应，使微生物菌种生产出GlNAc。

这种方法具有原料利用率高、环境友好等优点，受到了越来越多的关注。

2. 发酵法的优缺点使用发酵法制备GlNAc时，常见的优点是原料利用率高、环境友好，适用于可持续发展。

关键词：HPLC N-乙酰氨基葡萄糖硫酸氨基葡萄糖中图分类号：Ｒ９２７．２文献标识码：Ａ文章编号：１６７２－８３５１（２０１４）０５－００１９－０１硫酸氨基葡萄糖为天然的氨基单糖，是人体关节软骨基质中合成蛋白聚糖必需成分。

氨基单糖可刺激软骨细胞产生具有正常多聚体结构的糖蛋白，抑制某些可损害关节软骨的酶，抑制损伤细胞的超氧化物自由基的产生，防止皮质激素及某些非甾体类抗炎药对软骨细胞的损害，减少损伤细胞的内毒素因子的释放，目前其主要用于治疗和预防骨性关节炎以及食品添加剂[1]。

在生产过程中，由于N-乙酰氨基葡萄糖的溶解性质与氨基葡萄糖相似，故重结晶时常会出现少量N-乙酰氨基葡萄糖的残留[2]，为了有效控制硫酸氨基葡萄糖生产及贮存过程中产生的N-乙酰氨基葡萄糖，本研究建立了硫酸氨基葡萄糖相关物质N-乙酰氨基葡萄糖的HPLC测定法，现报道如下。

英文回答：The dietary supplements N-acetylglucosamine and glucosamine hydrochloride are widely recognized for their potential impact on joint health. The primary distinction between the two lies in their chemicalpositions. N-acetylglucosamine (NAG) represents a variant of glucosamine in which the amine group is acetylated, whereas glucosamine hydrochloride (GHCl) is a salt form of glucosamine. This structural variance engenders differences in their absorption and metabolic processes within the body. NAG is often lauded for its potential benefits in promoting skin health and serving as a precursor for the synthesis of glycosaminoglycans, which are key constituents of joint cartilage. Conversely, GHCl is predominantly employed for its purported effects on alleviating joint pain and managing osteoarthritis.饮食上对N—乙酰基氯胺酮和盐酸氯胺酮进行补充，因其对双方健康的潜在影响而得到广泛认可。
