NATURAL PRODUCT CHEMISTRY AND CHEMICAL ECOLOGY ON MITES AND INSECTS

从3种粉螨中鉴定出2种性信息素和1种报警信息素。从螨类中分离得到3个新化合物，其结构经合成确证。此外，还研究了粉尘性信息素的结构、活性关系及进化过程。对甲酚被鉴定为爱国多毛虫的主要防御化合物，而扁桃腈被鉴定为另一种华利氏常绿足虫的主要防御化合物。还对千足虫的防御性化学物质进行了综述。一种巨型大那那蝴蝶的毛笔成分被证明具有雄性信息素的功能，并阐明了它们由150多个化合物组成的化学结构。在50多种鳞翅目昆虫中发现了不常见的二烷基四氢呋喃类化合物。产卵刺激剂为(-)-4-(E)-(E)-咖啡酰基-L-苏糖酸盐，存在于冬虫夏草中。经鉴定，桔小实蝇雄虫性信息素为异松果醇，是花香中苯丙醇类化合物的产物。果蝇对热带花卉苯丙醇类香气具有很强的诱惑力，这是一种产生雄性信息素的食药性现象。同样，马来西亚果蝇的雄性信息素强烈地被甲基亮酚吸引，甲基亮酚被代谢成性信息素。此外，还对一种臭虫和一种果蝇的性信息素的化学结构进行了分析。经鉴定，该种蟑螂的吸引性聚集信息素是低级烷基胺的混合物。研究了这些挥发胺的构效关系和缓释机理。对德国蟑螂的生殖腺分泌物进行了生物学和化学研究。

Two sex pheromones and an alarm pheromone were identified from 3 species of acarid mites. Three compounds were newly isolated form mites and their structure was identified by synthesis. Structure activity relationships of mite sex pheromone and evolution process of mite pheromone were also studied.p-Cresol was identified as a major defence compound from polydesmida millipede Nedyopus patrioticus patrioticus, while mandelonitrile was identified from the other millpede Chamberlinius hualienensis. Defensive chemicals from millipedes is also reviewed.Hair pencil components from a giant danaine butterfly was demonstrated to function as the male sex pheromone and their chemical structures composed of more than 150 compounds were elucidated. The unusual dialkylterahydrofurans were detected as a common lipid component among more than 50 species of lepidoptera. For a Rutaceae-feeding swallowtail butterfly, the oviposition stimulant was identified as (-)-4-(E)-caffeoyl-L-threonate, present in Oriza japonica. The male sex pheromone of the Oriental fruit fly was identified as transconiferyl alcohol, which was derived from phenylpropanoide present in flower aroma. A strong attractiveness of the fruitfly to phenylpropanoid aroma of tropical flowers was a phenomenon of pharmacophagy for production of the male sex pheromone. Likewise, the male sex pheromone of Malaysian fruitfly was strongly attracted to methyleugeol, which was metabolized to function as the sex pheromone. Chemical structures of sex pheromones of a stinkbug and a fruit fly were also elucidated.Attractant aggregation pheromone of the German cockroach was identified as a mixture of lower alkylamines. Their structure activity relationships and the slow release mechanism of those volatile amines were investigated. The tergal gland secretion of the German cockroach were studied biologically and chemically.
