ON THE BIONOMY OF TOMICUS-PINIPERDA (L) (COL, SCOLYTIDAE) IN THE KUNMING REGION OF CHINA

The bionomy of the pine shoot beetle, Tomicus piniperda (L.), was studied in the field in Kunming, China. Tomicus piniperda in Kunming seems to develop some biological features, which distinguish it from those in some European countries. For example, the infestation on the living host trees, all the life stages occuring in winter, biological establishing of sister brood, and so on. This paper compares the characteristics of the European and Kunming beetles and suggests that the observed differences may be the results of the climate and the host pine in the Kunming region. Also, the paper introduces the pattern of shoot feeding and infestation on the trunks, and the reproduction rate of the pine shoot beetle.
