| Outline of Final Research Achievements |
The sugi bark borer, Semanotus japonicus (Coleoptera, Cerambycidae), is an important pest of Japanese cedar and Japanese cypress. The life span of the borer is usually one year. However, some individuals require two years in one generation. We found out that the larvae stopped pupating under low temperature condition, and such larvae required two years in one generation. In this case, full-grown larvae pass the first winter in the pupal chambers. They develop to the adults in the chambers without eating next summer. The adults pass the second winter in the chambers, and they emerged next spring.
