Tephrosia vogelii Hook was excellent insecticidal plant, it was introduced into China and planted over a large area in Guangdong province. The main active components of T. vogelii was rotenone and it widely found in leaves and pods of T. vogelii. This paper study of the safety assessment of T. vogelii flowers to worker bees. In this paper, the content of rotenone in T. vogelii petal, nectar, pollen, pistil, and stamen samples were investigated by HPLC, and tested the toxicity of T. vogelii flowers for Apis cerana cerana during 24 h. The dissipation and dynamic of rotenone in A. c. cerana different biological compartments were investigated under indoor conditions during 24 h. The results showed, The LT of T. vogelii flowers to worker bees were collected from the eastern, western, southern, northern and top were 13.95, 24.17, 12.55, 26.48, and 18.84 h, the haemolymph of worker bees have the highest content of rotenone, the least accumulation of rotenone in workers bee's thorax, and the rate of dissipation was slowly during the whole study. In conclusion, the results showed the T. vogelii create security risks to worker bees under some ecosystems.
Vogel 山绿豆是一种优秀的杀虫植物，它被引入中国，并在广东省大面积种植。T. vogelii 的主要活性成分是鱼藤酮，它广泛存在于 T. vogelii 的叶子和豆荚中。本文研究了 T. vogelii 花对工蜂的安全性评估。在本文中，通过 HPLC 研究了 T. vogelii 花瓣、花蜜、花粉、雌蕊和雄蕊样品中鱼藤酮的含量，并在 24 小时内测试了 T. vogelii 花对中华蜜蜂（Apis cerana cerana）的毒性。在室内条件下，研究了鱼藤酮在 24 小时内不同生物区室中 A. c. cerana 的消解和动态。结果表明，从东方、西方、南方、北方和顶部采集的 T. vogelii 花对工蜂的 LT 分别为 13.95、24.17、12.55、26.48 和 18.84 小时，工蜂血淋巴中鱼藤酮含量最高，工蜂胸部鱼藤酮积累最少，整个研究过程中消解速度较慢。总之，结果表明在某些生态系统下，T. vogelii 对工蜂构成安全风险。
