| Abstract: | From 1992 to 1995, aimed at 334hm 2 Pinus yunnanensis forest damaged by Tomicus piniperda in Shigouton village, Citongguan office, Beicheng town of Yuxi, the authors carried out a series demonstration and research including the control techniques related to forest culture and management, the techniques to control pest population. Through integrated control of 4 yeas, the rate of damaged tree in demonstration forest decreased from 62.67% to 3.72%, with the reduce rate of 94.06%, the damaged index decreased from 33.30 to 1.29 with the reduce rate of 96.1%. As far as the control forest of 34hm 2 is concerned, the rate of damaged tree increased from 39.03% to 90.47%, with the rise rate of 56.85% and the damaged index increased from 20.10 to 47.22 with the rise rate of 57.43%. The work has retrieved economical loss of 307900 Yuan, and thus improved the economic, social and ecological efficiency of Pinus yunnanensis. |
