NANNING, March 29 (Xinhua Xiong Hongming) sustained drought in southwest China could have devastating consequences for the forest area. Guangxi Zhuang Autonomous Region and Guangxi Zhuang Autonomous Region Meteorological Disaster Mitigation by forest pest control and quarantine station together pre-measured forest pest found that high temperature and drought led to pine forest areas in some cities and counties was an outbreak situation, local disasters seriously.
Guangxi Zhuang Autonomous Region Meteorological data provided by reduction, as of mid-March this year, Guangxi punctatus (including mushrooms moth) occurred an area of 40.60 million mu (15 mu = 1 hectare), compared with 1-fold increase over the same period last year. Among them, the pine area has reached 3.53 million mu of serious harm, is 7.6 times the same period last year. Among them, the pine severe drought in central and western parts of Guangxi, Nanning, Baise, outbreaks of Chongzuo City, Nanning City, is the worst hit place pine, 6.4 acres affected. In addition, the Hechi, Baise, Chongzuo and other areas hit by drought, pine active also very active.
Guangxi Zhuang Autonomous Region of forest pest control and quarantine station of the experts, the pine forest encroachment in pine, the needles will be eaten, as if burned too general, the bare one. Infringement by the pine after pine, timber growth reduced resin production cuts or crops, the victim will be dead serious pine. If Dendrolimus further development, it will lead into the forest of the overall ecological function decline. So researchers worry that the current central Guangxi, southern pine is mature forest in addition to some seriously affected larvae die of hunger because of lack of food or early cocoon, these adult feeding damage of caterpillars has entered the peak period If you do not take steps to cause serious harm.
Reporter learned from the Guangxi Forestry Department, in response to pest, Guangxi has produced 150,000 kg of Beauveria bassiana to fight against the pine. The Guangxi homegrown bio-pesticides can control pests around 60 mu. Forestry departments at all levels have started spraying control operations to prevent disaster from spreading. (END)
