Lucilia sericata is a facultative ectoparasite causing fly strike or myiasis in warm-blooded vertebrates. It is controlled by traps or insecticides, but both have drawbacks and alternative ways of control are urgently needed. Essential oils (EOs) of vetiver (Chrysopogon zizanioides), cinnamon (Cinnamomum zeylanicum), and lavender (Lavandula angustifolia) and their blends (OBs); OB1 (2 ml of each EO plus 4 ml of sunflower oil as a carrier) and OB2 (2 ml of each EO) were tested. Oils were tested at 5% for deterrence assays, and a dose response assay 0.01-0.6%, was conducted to determine forced-contact toxicity. We evaluated the efficacy of oils as oviposition deterrents, repellents/attractants, and their effects on mortality and longevity of adult L. sericata. Our data indicated that 0.2% EOs killed all flies by 5 min post-treatment and that vetiver oil greatly deterred flies from the oviposition medium and reduced adult longevity. Sunflower oil repelled all flies from ovipositing and greatly reduced the lifespan of treated adults. The blend of the four oils (OB1) had the greatest repellent effect on the flies. EOs have insecticidal, repellent, and oviposition-deterrent activities against L. sericata that could be used for suppression of blow fly populations.
丝光绿蝇是一种兼性体外寄生虫，可在温血脊椎动物中引发蝇蛆病或羊蝇蛆症。它通过诱捕器或杀虫剂进行控制，但两者都有缺点，因此迫切需要其他控制方法。对香根草（香根草）、肉桂（锡兰肉桂）和薰衣草（狭叶薰衣草）的精油（EOs）及其混合物（OBs）进行了测试；OB1（每种精油2毫升加4毫升向日葵油作为载体）和OB2（每种精油2毫升）。精油在5%的浓度下进行驱避试验，并进行了0.01 - 0.6%的剂量反应试验以确定强制接触毒性。我们评估了这些精油作为产卵驱避剂、驱避剂/引诱剂的功效，以及它们对成年丝光绿蝇死亡率和寿命的影响。我们的数据表明，0.2%的精油在处理后5分钟内杀死了所有苍蝇，香根草油极大地阻止了苍蝇在产卵介质上产卵并缩短了成年苍蝇的寿命。向日葵油使所有苍蝇不再产卵，并大大缩短了处理后成年苍蝇的寿命。四种精油的混合物（OB1）对苍蝇具有最大的驱避效果。精油对丝光绿蝇具有杀虫、驱避和产卵驱避活性，可用于抑制绿头苍蝇种群。
