摘　　要：通过高速乳化和超声分散的技术,以天然蜂蜡(BW)为基质包封农药三氟氯氰菊酯(LC),制备得到一种三氟氯氰菊酯蜂蜡纳米制剂(LC-BW)。通过红外光谱、粒径、叶面接触角、扫描电镜和透射电镜对LC-BW制剂进行了结构和形态表征,并测试了该制剂的缓释和抗光解能力,结果表明其具有较好的控制释放和抗光解能力。以甘蔗螟虫作为测试靶标,对LC-BW制剂进行了毒性和杀虫持效性测定,结果表明,该制剂比市场上相应乳油产品具有更好的杀虫持效性。In this study,through high-speed emulsification and ultrasonic dispersion technology,natural beeswax(BW)was used as a matrix to encapsulate lambda-cyhalothrin(LC),and a cyhalothrin-beeswax nanoformulation(LC-BW)was prepared.The structure and morphology of the nanoformulations were characterized by infrared spectroscopy,particle size,leaf contact angle,scanning electron microscopy and transmission electron microscopy.The sustained release and anti-photolysis capabilities of the nanoformulations were further tested,and the results showed that the LC-BW formulations have better capabilities of release-controlled and anti-photolysis.Finally,using the sugarcane borer as the test target,the toxicity and insecticidal persistence of the nanoformulations were evaluated.The results showed that the LC-BW nano-formulation has better insecticidal persistence than the corresponding emulsifiable concentrate products on the market.
