摘要:

目的 控制龙滩水电站蓄水后移民安置点的鼠密度,预防鼠传疾病的发生与流行。方法 采用间歇式投饵法对居民住宅和耕作区投放0.005%溴敌隆小麦颗粒毒饵,采用粉迹法和夹夜法进行灭前、灭后鼠密度调查。结果 安置点居民住宅室内灭前粉块阳性率平均为9.90%,灭后为2.04%,灭效为79.39%。耕作区灭前鼠密度平均为6.54%,灭后为1.08%,灭效为83.49%。灭鼠前后鼠密度差异有统计学意义(χ2值分别为64.33和32.15,P<0.01)。结论 此次灭鼠效果表明,采用的技术方案科学合理,组织措施有力,选择的药物、毒饵剂型和灭鼠时机等均适合库区移民安置点鼠类特点。

Abstract:

Objective To evaluate deratization effects for controlling rat populations in regions for resettlement after the reservoir was formed at the Longtan hydropower station and preventing occurrence and prevalence of rodent?borne diseases. Methods 0.005% bromadiolone baits of wheat grain were intermittently applied to the residential and farming areas. Powder trace and night trap methods were employed to measure the rat density before and after deratization. Results The powder?block positive rate in residential areas averaged 9.90% before deratization and 2.04% after bait deployment, with the reduction of 79.39%. The average rat density in farming areas was 6.54% and 1.08% before and after deratization, respectively, with the reduction rate of 83.49%. Statistically significant difference was observed in the rat densities before and after rodent control (χ2 values were 64.33 and 32.15, P<0.01). Conclusion The results of rodent control showed that the applied control measures were effective with well organized procedures and choice of drugs, formulations of toxic baits and timing based on rodent characteristics of local populations.
