The acute toxicities of xinaomycin TK to Brachydanio rerio, Daphnia magna Straus, Pseudokirchneriella subcapitata, Apis mellifera L. and Bombyx mori were investigated. According to the results, the 96 h-LC₅₀ value of xinaomycin TK to B. rerio was higher than 100 mg/L. And the 48 h-EC₅₀ value of xianomycin TK to D. magna was 1.48 mg/L. The 72 h-EyC₅₀ and the 72 h-ErC₅₀ value of xianomycin TK to P. subcapitata were 8.74 mg/L and 29.2 mg/L, respectively. The 96 h-LD₅₀ value of xianomycin TK to A. mellifera were 31.3 μg/bee by acute oral method and 39.9 μg/bee by acute contact method. The 96 h-LC₅₀ value of xianomycin TK to B. mori was over 2.00×10³ mg/L. The acute toxicity test showed that xianomycin TK is low risk to B. rerio, D. magna, P. subcapitata, A. mellifera and B. mori and it has medium toxicity to D. magna.
