为了探讨采用花香挥发物对大豆鳞翅目害虫进行生态防控的可行性,通过田间诱捕试验比较了常见花香挥发物琼脂胶包结样品的诱捕活性。结果表明,这些样品可以捕获3种夜蛾(银纹夜蛾、白条夜蛾、棉铃虫)和3种螟蛾(玉米螟、甜菜白带螟和豇豆荚螟),数量占优势的种类是甜菜白带螟。其中,对3种夜蛾引诱作用最强的是苯乙醛和乙酸苯甲酯组成的二元混合物,其次是苯乙醛和乙酸苯甲酯单剂。玉米螟成虫主要对二元混合物、苯乙醛和苯乙醇具有趋性。单纯的苯乙醛样品诱捕到的甜菜白带螟数量最多,显著优于苯乙醛和乙酸苯甲酯组成的二元混合物,肉桂醛和苯乙醇对甜菜白带螟也有很强的引诱作用。总体来看,苯乙醛和乙酸苯甲酯以165μL∶335μL混成的二元配方成型于琼脂胶,有望成为大豆田鳞翅目害虫生态治理的一项有潜力的替代性措施。
為瞭探討採用花香揮髮物對大豆鱗翅目害蟲進行生態防控的可行性,通過田間誘捕試驗比較瞭常見花香揮髮物瓊脂膠包結樣品的誘捕活性。結果錶明,這些樣品可以捕穫3種夜蛾(銀紋夜蛾、白條夜蛾、棉鈴蟲)和3種螟蛾(玉米螟、甜菜白帶螟和豇豆莢螟),數量佔優勢的種類是甜菜白帶螟。其中,對3種夜蛾引誘作用最彊的是苯乙醛和乙痠苯甲酯組成的二元混閤物,其次是苯乙醛和乙痠苯甲酯單劑。玉米螟成蟲主要對二元混閤物、苯乙醛和苯乙醇具有趨性。單純的苯乙醛樣品誘捕到的甜菜白帶螟數量最多,顯著優于苯乙醛和乙痠苯甲酯組成的二元混閤物,肉桂醛和苯乙醇對甜菜白帶螟也有很彊的引誘作用。總體來看,苯乙醛和乙痠苯甲酯以165μL∶335μL混成的二元配方成型于瓊脂膠,有望成為大豆田鱗翅目害蟲生態治理的一項有潛力的替代性措施。

To develop an effective floral-based attractants for ecologically controlling the major moth pests in Glycine max field ,the study compared the trapping effect of several common floral voletiles formulated in agaropectin through field trapping experiment .The result showed that these volatiles could catch three noctuid moth species (A rgy rogramma agnata ,A .albostriata ,and Helicoverpa armigera) and three pyralid moth species (Ostrinia f urnacalis ,Hymenia recurva-lis ,and Maruca testulalis) ,in which H .recurvalis was the most abundant species in fall G .max field .Among the volatiles ,the binary blend of phenylacetaldehyde and benzyl acetate exhibited the strongest attractiveness to the three noctuid species ,followed by the single component used alone .T he binary blend ,phenylacetaldehyde ,and phenylethyl alcohol could catch significant num-bers of O .f urnacalis moths .However ,H .recurvalis moths were caught with the largest number in the traps baited with phenylacetaldehyde alone ,which was significantly stronger than the bina-ry blend ,and cinnamicaldehyde and phenylethyl alcohol also showed somewhat activity to this species .All together ,among the test floral volatiles ,a binary blend mixed with phenylacetalde-hyde and benzyl acetate(165 μL∶335μL) and formulated in agaropectin ,could be a promising al-ternative control measure against multiple co-occurring Lepidopteron pest species .
