项目摘要

To make clear the phenomena of periodical outbreak of a Diplopoda(Parafaontaria laminata armigere), the dynamics and growth of populations of P. laminata armigera were studied in two forests of larch and Quercus mongolica in Tateshina Mountain in Nagano prefecture. From this study, it became clear as followings;1. The responce of the metabolic rate of the of P. laminata armigera, which was observed to swarm in in the outbreak years, was high at low temerature and metabolic rate of the adult Diplopoda was less affected by temperature in comparison with that of the lervae.2. The phenomenon of the outbreak was related closely to the the larch forest from some causes. The swarming og the Diplopoda was considered as the movement from larch forest to Q. mongolica forest to grasslands for high quality food.3. The reason of one generation maintenance of P. laminata armigera populations was not clearized in this stury.4. The datum of temperature of environment where P. laminata armigera live were aquisited from July in 1985 to July in 1987 in the two forests in Nagano prefecture.

摘要为了明确一种双足目昆虫（Parafaontaria laminata armigere）的周期性爆发现象，在长野县塔中山的落叶松和蒙古栎林中研究了该昆虫的种群动态和生长情况。从这项研究中，可以清楚地看出以下几点：1。暴发年大量聚集的叠层棉铃虫代谢率在低温条件下的响应较高，且成虫代谢率受温度的影响较小，而幼虫代谢率受温度的影响较小。这一现象的发生与落叶松林有密切的关系。梁足类动物的成群活动被认为是从落叶松林到蒙古针叶松林再到草地以获取优质食物的运动。本研究未明确斑叶棉铃虫种群维持一代的原因。本文于1985年7月至1987年7月在长野县的两处森林中采集了分层棉铃虫生活环境的温度资料。
