不同植物材料对烟草甲成虫选择行为的影响

摘要

Plant matrials as Ailanthus altissima Swingle bark, Cnidium monnieri (L.) fruit, Aipinia ofifcinarum Hance rhizome, Elsholtzia stauntonii Benth fruit, Xanthium sibiricum Patrin fruit, Cinnamomum cassia Presl pericarp, Folium artemisiae Argyi plant, Nicotiane tabacum L. leaf, and Triticum aestivum L. kernel ( and whole flour) were used to study their effects on selective behavior of adult Lasioderma serricorne (Coleoptera:Anobiidae). Results showed that N. tabacum leaf, X. sibiricum fruit, C. monnieri fruit and T. aestivum kernel (whole flour) showed strong attractiveness to L. serricorne adults, with selection coefficient over 43.00%. The number of L. serricorne adults attracted by these plant materials was signiifcantly more than that attracted by control material. Whole wheat lfour had nearly the same attractiveness as tobacco leaf powder. A. altissima bark and A. ofifcinarum rhizome (natural state and powder) exhibited potent repellency to L. serricorne adults, with selection coefifcient of-56.25%and-62.50%respectively. The number of L. serricorne adults distributed in these two plant materials was signiifcantly less than that distributed in control.%采用Y型嗅觉仪在实验室内研究了臭椿树皮、蛇床子、高良姜根茎、木香薷、苍耳子、桂皮、艾叶、烟叶和麦粒（全麦粉）等植物材料对烟草甲成虫选择行为的影响。结果表明：烟叶、苍耳子、蛇床子、麦粒（全麦粉）对烟草甲成虫的引诱作用较强，烟草甲成虫的选择系数均在43.00%以上，其引诱的试虫数显著多于对照引诱的试虫数；全麦粉与烟叶粉末的引诱作用相当。臭椿树皮和高良姜根茎（正常状态和粉末状态）对烟草甲成虫均表现出较强的忌避性，烟草甲成虫对臭椿树皮和高良姜根茎的选择系数分别为-56.25%和-62.50%，二者气味源中的试虫数显著少于对照。
