目的 :评价食品行业的灭鼠效果 ,探索适合这类行业的灭鼠毒饵。方法 :配对观察商品毒饵与自配毒饵的拖食率差异 ,用粉块法考核鼠密度下降率。结果 :商品毒饵拖食率远低于各种自配毒饵 (P <0 .0 1) ,鼠密度下降率前者在 50 %以下 ,后者达 84 .61%～ 97.0 0 %。结论 :根据食品行业的特点 ,必须选用适合该行业优势鼠种的新鲜饵料 ,在技术人员的监督下配制毒饵 ,提高灭鼠效果
PURPOSE: To evaluate the anti-rodent effect in the food industry and to explore rodent-poisoning bait suitable for this type of industry. Methods: Paired observation of the difference between the rate of tragacanth of commercial bait and self-bait bait, the decline rate of rat density was tested by the method of powder block. Results: The drag rate of the commercial bait was much lower than that of the self-formulated bait (P <0.01). The former was less than 50% and the latter 84.61% -97.0%. Conclusions: According to the characteristics of the food industry, fresh baits suitable for the dominant species of the industry must be selected, and bait should be prepared under the supervision of technicians to improve the anti-rodent effect
