用B2和C型“克虫王”两种鱼用药物对蚤状氵蚤和裸腹氵蚤进行了急性毒性试验。结果表明 :B2型“克虫王”对蚤状氵蚤的 48hTLm (半致死浓度 )为 0 96mg/L ,安全浓度为 0 0 96mg/L ;对裸腹 氵蚤的 10hTLm为 0 0 114mg/L。C型“克虫王”对蚤状 氵蚤和裸腹氵蚤的 48hTLm分别为 1 8mg/L和 0 37mg/L ,安全浓度分别为 0 18mg/L和 0 0 37mg/L。裸腹 氵蚤对这两种药物的敏感性显著高于蚤状氵蚤。
Acute toxicity test on flea and flea belonged to two types of fish, B2 and C. The results showed that the 48 hTLm (LD50) and the safe concentration (0 966 mg / L) of type B2 “Keto king” were respectively 0 96mg / L and 0 0 114mg / L . The 48 hTLm of C-type “Kettle-king” to flea and flea was 18 mg / L and 37 mg / L respectively, and the safe concentrations were 0 18 mg / L and 0 37 mg / L, respectively. Daphnia magna was significantly more susceptible to both drugs than flea fleas.
