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。从螨类中新分离得到三个化合物，并通过合成鉴定了其结构.研究了螨类性信息素的构效关系和进化过程，鉴定出对甲酚是千足虫Nedyopus patrioticus的主要防御化合物，扁桃腈是另一种千足虫Chamberlinius hualienensis的主要防御化合物。本文还综述了千足虫的防御性化学物质，并从一种大灰蝶的毛笔中鉴定了150多个化合物的化学结构。不寻常的二烷基四氢呋喃被检测到作为一种常见的脂质成分在50多种鳞翅目昆虫。对取食芸香科植物的燕尾蝶而言，其产卵刺激物被鉴定为（-）-4-（E）-咖啡酰-L-苏糖酸酯，存在于日本小花蝽中。东方实蝇的雄性信息素经鉴定为transconiferyl alcohol，其来源于花香中的苯丙素。果蝇对热带花卉苯丙烷类香气的强烈吸引是产生雄性性信息素的一种食药现象。同样，马来西亚果蝇的雄性性信息素强烈吸引甲基丁香酚，这是代谢的性信息素的功能。对一种蝽象和一种果蝇的性信息素的化学结构进行了分析，并鉴定了德国小蠊的引诱聚集信息素是一种低级烷基胺的混合物。研究了它们的构效关系和缓释机理。本文对德国小蠊的背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.
