| 本文通过研究两种外来入侵植物精油对仓储害虫印度谷螟的杀虫活性，提供“以草治虫”新方法并对两种入侵植物的实用性增加新用途。通过利用浸渍法、滤纸药膜法以及密闭容器熏蒸法测定了入侵植物马缨丹Lantana camara和南美蟛蜞菊Wedelia trilobata精油对印度谷螟Plodia interpunctella幼虫的杀虫和驱避作用及成虫的熏蒸作用。马缨丹精油杀虫效果高于南美蟛蜞菊精油，在浓度为30 μL/mL处理时间为96 h下两种精油杀虫效果最佳，马缨丹杀虫校正死亡率为89.13%，南美蟛蜞菊杀虫校正死亡率为74.64%。两种植物精油在浓度为80 μL/mL下驱避率较高，其中马缨丹精油在80 μL/mL浓度2 h处理下驱避率为73.330%，驱避等级为IV级。南美蟛蜞菊精油在80 μL/mL浓度2 h处理下驱避率为83.996%，驱避等级为V级。两种植物精油熏蒸作用来看，马缨丹植物精油效果好于南美蟛蜞菊植物精油效果。在对成虫熏蒸处理下相同处理时间内，马缨丹精油的LC50值均低于南美蟛蜞菊植物精油的LC50。南美蟛蜞菊精油驱避率相比马缨丹精油驱避率较高，南美蟛蜞菊精油杀虫、熏蒸效果没有马缨丹精油杀虫、熏蒸效果强，表明两种入侵植物对防治印度谷螟有一定功效。 |
| 英文摘要: |
| This study assessed the potential of essential oils from Lantana camara and Wedelia trilobata as botanical control agents against Plodia interpunctella, offering a novel pest management method and a potential utilization pathway for these invasives. The insecticidal and repellent effects on larvae were assessed via the dipping and filter paper methods, respectively, while the fumigant effect on adults was tested using the sealed container method, all with the essential oils of L. camara and W. trilobata. The insecticidal effect of Lantana camara essential oil was more pronounced than that of Wedelia trilobata, with both oils exhibiting peak efficacy at the concentration of 30 uL/mL after 96-hour exposure period. The corrected mortality for L. camara and Wedelia trilobata was 89.13% and 74.64%, respectively. At a concentration of 80 uL/mL both plant essential oils showed relatively higher repellency.. However, Wedelia trilobata demonstrated superior performance, yielding the repellency of 83.996% (Grade V) after 2 hours, notably higher than the 73.330% (Grade IV) observed for L. camara. A finding corroborated by its lower LC50 value, L. camara?essential oil exhibited a more potent fumigant effect than that of?W. trilobata. In contrast,?W. trilobata?essential oil showed superior repellency; however, its efficacy in directly killing pests, whether by contact or fumigation, was consistently lower. The findings demonstrate that both invasive plants possess promising efficacy for controlling?Plodia interpunctella, highlighting their potential as botanical control agents. |
