糖醋酒液是诱杀蛾类成虫的一项重要措施,诱虫谱广,雌雄兼诱。然而,对益虫以及害虫选择性差、成本过高制约了该技术的农田的大规模应用。笔者采用配方均匀设计将一系列糖醋酒配方成型于琼脂凝胶进行了诱捕试验。结果表明:①糖醋酒琼脂凝胶诱芯可以诱捕,甜菜夜蛾、银纹夜蛾、棉铃虫、白条夜蛾、小地老虎5种,螟蛾有玉米螟、桃蛀螟、甜菜白带螟、豇豆荚螟、稻纵卷叶螟5种,还能诱到许多天敌昆虫和授粉昆虫。鳞翅目中2个最大的科夜蛾科和螟蛾科害虫的诱捕量与乙酸和乙醇的交互作用呈显著相关关系,但与红糖的存在与否差异不大;相反,益虫总诱捕量则与红糖剂量对数值显著有关。乙酸和乙醇必须同时存在,减少红糖用量对鳞翅目害虫的诱捕没有影响,但有助于提高诱杀害虫/益虫比,并有助于降低成本;②糖醋酒凝胶诱芯与典型的花香引诱剂的诱虫谱明显不同。前者夜蛾类害虫诱捕量占总诱捕量的59.05%,螟蛾类占26.15%;而后者中夜蛾类占27.99%,螟蛾占66.02%,说明两大类鳞翅目成虫存在着显著气味偏好性分化,夜蛾中除了金翅夜蛾亚科的种类外均偏好发酵产物和高浓度的糖,尤其是切根夜蛾亚科的地老虎类,而螟蛾则偏好花香气味。
Sweet and sour wine is an important measure to induce adults to kill moths. It has a wide range of attractant insects, both male and female. However, the poor selectivity of beneficial insects and pests, the high cost of agricultural technology restricts the large-scale application of the technology. I use the formula uniform design will be a series of sweet and sour wine formulations in the agar gel trapping test. The results showed that: (1) There were 5 kinds of trapping of beet armyworm, beet armyworm, Spodoptera litura, cotton bollworm, white striped armyworm and small tiger tiger, and corn borer, , Cowpea pod borer, rice leafroller 5 species, but also induced many natural enemies of insects and pollination insects. Lepidoptera in Lepidoptera two largest Nymphalidae and Pyralidae trapping amount of acetic acid and ethanol interaction was significantly related to the existence of brown sugar or not significant difference; the contrary, the total beneficial insect entrapment amount Significantly related to the dose of brown sugar. Acetic acid and ethanol must exist at the same time, reducing the amount of brown sugar has no effect on the trapping of lepidopteran pests but helps to increase the trapping rate of pests / beneficial insects and helps to reduce the cost. ② The sweet and sour wine gel induces the typical floral Attractant traps significantly different. The former accounted for 59.05% of the total entrapment, and the moths accounted for 26.15%. The latter accounted for 27.99% of the total, and the stem moths accounted for 66.02%, indicating that there were significant odors Preferentially differentiated, except for the genus Ribesculina subfamily, the latter preferred the fermented products and high concentration of sugars, especially the terrestrial tiger of the subfasciatum, while the moth preferred the floral aroma.
