蟑螂性費洛蒙及青春激素類似物之應用簡介
The Application of Pheromones and Juvenile Hormone Analogs on Cockroaches
摘要
蟑螂性費洛蒙是同種雖雄蟑鄉間傳遞交尼訊．包之化學物質，主要由雖蟲產生，目前已知美洲、德國及日本蟑螂之性費洛蒙已被純化鑑定，前二者已經有機合成，合成物經生物檢定證實有效。美洲蟑鄉之性費洛蒙是 periplanone-B 和 periplanone-A，德國蟑螂為3,11-dimethyl-2-nonacosanone、29-hydroxy-3,11-dim-ethyl-2-nonacosanone和29-oxo-3,11-dimethyl-2-nonacosonone，日本蟑鄉為 Periplanone-J。部份合成品已經商品化用朴誘蟲試驗，有顯著之引誘效果。青春激素類似物是模擬死蟲青春激素之化學合成品，它可模擬青春激素的生理作用，使幼蟲或若蟲保持在幼期狀態，或使成蟲生殖器官分化不完全，因而失去成蟲的繁殖力，目前被引薦用矜璋螂的有 hydroprene、pyriproxyfen 及 fenoxycarb ，經實臉證明，在經過使用一段時聞之彼，蟑螂族群會際得很低。由矜種種因素，使得性費洛蒙及青春激素類似物合用時，其效果更為明顯，所以將來如能將兩者合用，更可收我長補短之效。

The sex pheromone of cockroaches is the chemical which transmits the copulation signal between female and male roaches of the same species. It is produced by virgin females in most roaches, and the chemical structures have been identified for the American, German and Japanese cockroaches. Penplanone-B (PB) and periplanone-A (PA) have been synthesized in the laboratory and tested both in lab and field, showing good biological responses.The sex pheromones of the German cockroach are 3,1 l-dimethyl-2-nonacosanone, 29 -hydroxy- 3 ,ll-dimethyl-2-nonacosanone and 29-oxo-3,1 l-dimethyl-2-nonacosanone, and because of their low volatile nature, they would not be used up in a short time. Periplanone-J (PJ) is produced by the Japanese cockroach. The juvenile hormone analogs (JHA) are chemicals which mimic the juvenile hormones (JH). They have the physiological actions of JH which are maintaining the larvae and nymphs in their immature stages or making the reproductive organs differntiate incompletely, and thereby interfering with their reproduction. The JHA which have been commercialized to control roaches are hydroprene, pyriproxyfen and fenoxycarb. The first two have been proved to reduce the roach population in field tests in the USA and Japan.For some reason,if the sex pheromone and the JHA are used together,the net effect will be more than if they are used alone.In the presence of the sex pheromone,the cockroaches’ movements increase, so the chance for a roach to contact the sprayed JHA is also increased. This might be the possible reason for the above observation.
