The aim of the research was to identify efficacious and less environmentally harmful treatments than the standard chlorpyrifos sprays used for the control light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), eggs on nursery stock. A series of dip experiments showed a range of responses when comparing the efficacy of insecticides on egg hatch of E. postvittana. The insecticides that compared most favorably with chlorpyrifos were lamda-cyhalothrin and gamma-cyhalothrin, and thiacloprid. Indoxacarb, novaluron, and spinosad caused significant mortality only when combined with All Seasons mineral oil. All Seasons, showed ovicidal properties when evaluated alone and demonstrated adjuvant properties when combined with the above-mentioned insecticides, except gamma-cyhalothrin and thiacloprid. Several other horticultural mineral oils performed similarly, except the efficacy of spinosad varied with the oil product used, suggesting that the oil type selected is important for some insecticide and oil combinations. Several insecticides evaluated in this study are likely candidates for further work to develop treatments against E. postvittana eggs on nursery plants. Mineral oils are ovicidal and combinations with insecticides are likely to be advantageous.
本研究旨在寻找比用于防治 nursery stock 上的 Epiphyas postvittana (Walker) (鳞翅目：卷蛾科)卵的标准氯菊酯喷雾更有效且对环境危害更小的处理方法。一系列浸渍实验表明，比较了几种杀虫剂对 E. postvittana 卵孵化的效果，存在一系列不同的反应。与氯菊酯相比，效果最好的杀虫剂是 lambda-氯氟氰菊酯和 gamma-氯氟氰菊酯，以及噻虫啉。茚虫威、novaluron 和多杀菌素只有与 All Seasons 矿物油结合使用时才会导致显著的死亡率。All Seasons 单独评估时具有杀卵特性，与上述杀虫剂结合使用时具有增效作用，但 gamma-氯氟氰菊酯和噻虫啉除外。其他几种园艺矿物油的效果类似，但由于所用油产品的不同，多杀菌素的效果也有所不同，这表明选择油类型对于某些杀虫剂和油的组合很重要。本研究中评估的几种杀虫剂很可能是进一步开发防治 nursery 植物上 E. postvittana 卵的处理方法的候选者。矿物油具有杀卵作用，与杀虫剂结合使用可能具有优势。
