The distribution area and damage of the major sugarcane borers in Yunnan sugarcane areas were ascertained, and the factors influencing population structure dynamics of sugarcane borers and their rampant causes were revealed. According to the damaging characteristics of sugarcane borers, suitable control countermeasures were proposed, including establish-ing and improving sugarcane quarantine system, enhancing quarantine of imported varieties/clones, investigating new sugarcane borer populations thoroughly and systematically, establishing early warning and monitoring system, actively carrying out physical and biological control, and enhancing protection of natural enemies. These countermeasures could help to effectively control sugarcane borers and reduce the damage caused by these borers.展开更多

Occurrence characteristics and rule of rainstorm and flood disaster were found,and disaster situation was evaluated and analyzed. The results showed that( 1)there was almost local rainstorm and flood in Shaoyang City every year,with strong seasonal characteristic.( 2) The loss caused by rainstorm and flood disaster was the most serious in various meteorological disasters.( 3) Rainstorm and flood disaster generally had the sudden and devastating characteristics. Via the analysis and research on rainstorm and flood disaster,defense measure and countermeasure of rainstorm and flood were proposed,which could provide scientific decision basis for party and government leading flood relief,and had important guidance significance for preventing and mitigating disasters by government agencies.展开更多
