摘　　要：黄粉虫(Tenebrio molitor)是一种造成损失较为严重的世界性储粮害虫。本研究发现层生镰刀菌菌株21.1侵染的大米、小麦及玉米3种主粮基质均能够不同程度地吸引黄粉虫幼虫;运用GC-MS技术初步判断层生镰刀菌吸引黄粉虫幼虫的主要有机挥发物成分为β-石竹烯;将β-石竹烯标准品配制成1000 mg/L并添加到高温灭菌的大米、小麦及玉米基质中,其对黄粉虫幼虫有明显的吸引作用。本试验结果对防治储粮害虫(黄粉虫)具有重要意义。Yellow mealworm(Tenebrio molitor)is a kind of worldwide pest for stored grains causing seri-ous damage.It was found that rice,wheat and maize substrates infected by Fusarium proliferaum 21.1 could attract T.molitor larvae to different degrees.Using GC-MS technique,it was preliminarily determined thatβ-caryophyllene was the main organic volatile component of F.proliferatum attracting T.molitor larvae.Theβ-caryophyllene standard product was prepared into 1000 mg/L solution,and then was added into the high-tem-perature sterilized rice,wheat and maize substrates,it showed obvious attraction to T.molitor larvae.The ex-periment results was of great significance to controling grain storage pests(T.molitor).
