| 中文摘要: |
| 本研究针对螺虫乙酯对柑桔主要害虫(桔全爪螨、锈壁虱、矢尖蚧和柑桔粉虱)的防治效果进行了系统评估,并分析了其药剂安全性。结果显示,22.4%螺虫乙酯悬浮剂在不同稀释倍数下对上述害虫具有显著的防治效果,尤其在中后期表现出稳定的持效性。具体而言,对桔全爪螨的防效稳定在87.56%～98.97%,速效性和持效性均表现优异；对锈壁虱的防效为85.19%～95.98%,持效期较长；对矢尖蚧低龄若虫的防效可达84.93%,与常用药剂无显著差异；对粉虱低龄若虫的防效为78.83%,略逊于部分高效药剂但仍有较好应用价值。此外,试验结果表明,螺虫乙酯对柑桔叶片和果实无药害影响,且对有益生物安全无害。因此,该药剂适合长期应用于柑桔害虫的综合治理。 |

| This study systematically evaluated the control effect of spirotetramat against four major citrus pests (including citrus red mite, citrus rust mite, arrowhead scale, and citrus whitefly) and analyzed its safety as a pesticide. The results showed that the 22.4% spirotetramat suspension agent demonstrated significant control effects on the aforementioned pests at different dilution multiples, particularly exhibiting stable residual efficacy in the middle and later stages. Specifically, the control efficacy on citrus red mites was stable between 87.56% to 98.97%, showing excellent quick-acting and residual properties. The efficacy on rust mites ranged from 85.19% to 95.98%, with a long-lasting residual effect. The efficacy on young nymphs of arrowhead scales reached 84.93%, showing no significant difference compared to commonly used pesticides. And the efficacy on young nymphs of whiteflies was 78.83%, slightly inferior to some highly effective pesticides but still having good application value. Additionally, the experimental results indicated that spirotetramat caused no phytotoxicity on citrus leaves and fruits and was safe for beneficial organisms. Therefore, this agent is suitable for long-term use in the integrated management of citrus pests. |
