抄録

The effectiveness of a new acute rodenticide, Pyriminyl (RH-787) to rats and mice was investigated. As a result, the LD_<50> values of technical were 24.4-26mg/kg in male rats, 12.2-27.9mg/kg in female rats, 68.8-90mg/kg in male mice, and 56-68mg/kg in female mice. These values resemble closely that of thallium sulfate and zinc phosphide which are being used practically at present. In the experiments conducted using only 2% baits, all mice died in 1 day later and all rats died within 5 days. Secondly in the experiments of the choice test between 2% baits and rolled barley, no difference of acceptance was observed on mice, but rats showed a little low acceptance to poison baits. In the preliminary experiments using 1% powdered baits and powdered nonpoison baits, however, no avoidance to poison baits was observed on rats and ll died within 2 days. From the above described, Pyriminyl might be anticipated as a promising acute rodenticide in future by adding further more information concerning formulation and concentration.
