谷象对植物油和信息素趋性反应的研究

Studies on the taxis reflection of Sitophilus granarius L. to some vegetable oils and its pheromone

谷象成虫对部分植物油和信息素的趋性反应在室内被测试。结果表明冷榨未精炼的麦芽油、能量油、燕麦油对该虫有强的引诱作用。“Sitophilate”信息素对谷象雌雄两性成虫均有聚集反应，但高浓度时，其诱虫活性降低。在瓦楞纸诱捕器中，信息素结合麦芽油或燕麦油其诱虫活性明显优于燕麦油或麦芽油单独使用。

Taxis reactions of Siiophilus gronarius L. to vegetable oils and pheromone were testedindoor. oils of wheat germ, energol and oat were more attractive than mineral oil. Phcromone asse-mbled both male and female adults of granary weevils. However, higher concentration reduces theattraction. In cardboard trap, the attraction of phexomone combined with germ oil or oat oil was supe-rior to oils alone.
