The factors controlling the component ratio and the content of the sex pheromone were examined in the potato tuberworm moth, Phthorimaea operculella. This species is known to have a huge individual variation on the component ratio. On the ratio of two pheromone components, the genetical factor was thought to be a minor one because the variation of the ratio did not decrease as a continuous inbreeding was conducted. Instead, some environmental factors like rearing temperature modified the ratio. Triene % increases in higher temperature, while it decrease in lower. By the experiments following pheromone content with female age after emergence, it was clarified that the diene component was synthesized after emergence. The bio-synthetic speed of diene was controlled by ambient temperature condition, strongly. Therefore, the diene % reached to 25 ﾟC level at one day later. On the other hand, the pheromone content was controlled genetically. The author could get a ''high pheromone content strain'' during continuous inbreedings.To analyze the emitted pheromone, an air-borne collection apparatus was also designed. The apparatus are still improving for more efficient collection.

对马铃薯块茎蛾性信息素组分比例和含量的控制因素进行了研究。已知该物种在组分比例上具有巨大的个体差异。关于两种信息素组分的比例，遗传因素被认为是次要因素，因为随着连续近交的进行，该比例的变化并没有减少。相反，一些环境因素，如饲养温度修改的比例。三烯%随温度升高而增加，随温度降低而降低。通过对羽化后信息素含量随雌虫日龄变化的跟踪试验，阐明了二烯类成分是在羽化后合成的。二烯的生物合成速度受环境温度条件的强烈控制。因此，二烯%在一天后达到25 ° C水平。另一方面，信息素含量受遗传控制。作者还设计了一种空气收集装置，用于分析其散发的信息素。为了更有效地收集，该设备仍在改进中。
