高原鼠兔的精确性可持续控制技术研究——几种杀鼠剂的对比试验

A study on accurate,sustainable,control technology for plateau pika(Ochtona curzoniae)——Comparative experiment on several rodenticides

于2007年4-5月份在甘肃肃南县对防治高原鼠兔精确用药进行试验,将5种常见杀鼠剂的推荐用药浓度、用药量按等比级数增、减剂量进行插组,作正交对比试验,结果表明,推荐用药浓度、用药量和饵料种类与调整后的用药浓度、用药量和饵料种类对高原鼠兔的灭洞率有一定的差异性。影响灭洞率的主、次因子顺序是:杀鼠剂>用药浓度>投饵量>饵料种类。以防效为评价指标,5种参试杀鼠剂的排序为:大隆(83.9%)>D型肉毒梭菌生物毒素(82.6%)>溴敌隆(79.4%)>C型肉毒梭菌生物毒素(75.0%)>敌鼠钠盐(68.9%)。最佳处理组合是:1)用0.15%的D型肉毒梭菌生物毒素、小麦饵料、25粒投饵量;2)0.01%大隆、青稞饵料、5 g投饵量;3)0.01%溴敌隆、小麦饵料3、g投饵量。

During April and May 2007, a rodenticide experiment was conducted on control of plateau pika in Sunan, Gansu province. Recommended drug densities and drug values of five rodenticides were adjusted by geometrically increased and decreased values using an orthogonal design. There were differences between recom- mended values, actual drug densities, drug consumption, bait types, and of adjusted values and types in killing efficiency on plateau pika in the test region. Primary and secondary factors affected killing efficiency and tended to decrease in the order rodenticide types〉drug densities〉bait consumption〉bait types. Five kinds of tested rodenticides were in the order Talon （83.9%） 〉 Botulin type D （82.6 %）〉 Bromadiolone （79.4%） 〉 Botulin type C （75.0%）〉Diphacinone sodium salt （68.9%） according to the assessment index based on control effect. The three optimum treatment combinations were 0. 15% Botulin type D, wheat bait, 25 grains bait; 0. 01% Talon, naked barley bait, 5 g bait; 0.01% Bromadiolone, wheat bait, 3 g bait.
