摘要
目的 探明灭鼠对害鼠群落结构的影响 ,为鼠害预测和防制提供依据。方法 1987～ 2 0 0 0年 ,每年春、秋季使用第一代慢性灭鼠剂进行大面积全方位农田灭鼠 ,每次灭鼠实行饱和投饵 ;逢双月用夹夜法调查害鼠的种类、数量和生物量。结果 灭鼠导致板齿鼠的比率、生物量显著上升 ,黄毛鼠的比率和生物量明显下降 ,农田鼠类群落结构和害鼠群落多样性指数发生变化。结论 灭鼠会使耐药力较强、体大竞争力强的害鼠数量上升 ,防制的主要对象增加。
Objective To study the action of chemical control on rodent community structure for rodent forecast and control.Methods The anticoagulate rodenticides were used to control farmland rodents in spring and summer every year,the species,density and biomass of farmland rodents in Guangdong province were investigated with night trapping method from 1987 to 2000. Results After use of anticoagulate rodenticides for a long time, the percentage and biomass of Bandicota indica increased distinctly and those of Rattus rattoides reduced, and brought about changes to the rodent community structure and the index of diversity of farmland rodent community. Conclusion Chemical control resulted in the increase to the density of those rodents with larger size and stronger endurance to the rodenticide.
