摘要
葱蝇是危害大蒜的重要的根蛆类害虫,长期依赖化学杀虫剂导致害虫田间抗药性水平逐年积累,并严重威胁环境安全和人类健康。为了明确大蒜品种对葱蝇的抗性差异并探讨其抗虫机制,本研究分析了取食不同品种大蒜对葱蝇生命参数的影响,调查了田间大蒜品种间葱蝇发生危害差异,测定并分析了不同品种大蒜素含量与抗虫性的相关性。结果表明,取食杞县蒜和苍山蒜对葱蝇生命参数的抑制效果显著高于取食四六瓣蒜和宝坻蒜,表现为幼虫发育历期延长,蛹重减轻,幼虫存活率下降,成虫寿命缩短并伴随繁殖力下降;田间调查发现葱蝇对杞县蒜和苍山蒜的危害程度显著低于四六瓣蒜和宝坻蒜;此外,杞县蒜和苍山蒜的大蒜素含量显著的高于四六瓣蒜和宝坻蒜,且不同品种间大蒜素含量差异与抗虫性差异表现为显著的正相关。综上所述,大蒜素含量较高的大蒜品种对葱蝇的抗性较强,选育并栽培高大蒜素含量的大蒜品种对于提高大蒜品质和减轻根蛆危害有重要作用。
Delia antiqua(Meigen)is one destructive root maggot species to garlic.However,long-term dependence on chemical insecticides can lead to the accumulation of insecticide resistance in the field and a serious threat to environmental safety and human health.In order to determine the resistance of differences 7 varieties garlic to D.antiqua and explore the resistance mechanism,we detected the effects of different garlic varieties on the D.antiqua life parameters,compared the difference damage among garlic varieties in the field,and analyzed the correlation between allicin content and the resistance of different garlic varieties.The results indicated Qixian and Cangshan garlic exhibited stronger inhibitory effect on the life parameters of D.antiqua than that of Siliuban and Baodi garlic,such as prolonged larval development,reduced pupal weight,decreased larval survival,and shortened adult lifespan accompanied by decreased fecundity.The field investigation results indicated the D.antiqua damage on Qixian and Cangshan garlic was significantly lower than that of Siliuban and Baodi garlic.In addition,the allicin content of Qixian and Cangshan garlic was significantly higher than that of Siliuban and Baodi garlic,there was a significant positive correlation between allicin content and insect resistance.In conclusion,the garlic varieties with higher allicin content have the higher resistance against D.antiqua.Breeding garlic varieties with higher allicin content is important for improving the garlic quality and reducing the harm of root maggots.
