| Abstract: | Cyclophragrna laiipennis is a newly found pest in Guangdong. It is the major pest harmful to Castanopsis hystrir. It produces one generation a year, lives through the winter as eggs in the bark. It hatches at the middle of the coming February, becomes cocoons at the middle of September and emerges at the late November. The larvae have 7 ages and is active just at night. Survival rate of both eggs and low aged larva are low in nature forest situation. Mature forest and trees at the edge are easy to be damaged by Cyclophragma latipennis. |
