摘要: 卫矛是常见的绿化植物,而秋家蝇Musca autumnalis De Geer是畜牧业的重要昆虫。在室内利用Y型嗅觉仪对欧洲卫矛Euonymus europaeus和胶东卫矛E. kiautschovicus气味对秋家蝇Musca autumnalis De Geer的引诱效果进行了研究。结果表明:两种植物都对秋家蝇的雌性成虫有引诱作用,而欧洲卫矛引诱效果更好。进一步对叶和花的气味进行的观察表明,卫矛吸引秋家蝇主要依靠花的气味,但叶的气味也有一定的吸引作用; 叶的气味对花的引诱效果有增效作用。利用几种试剂(水、乙醇和正己烷)对欧洲卫矛花的气味物质进行了抽提,测试结果表明水或乙醇抽提物比正己烷抽提物引诱效果更好; 冷冻花与新鲜花的引诱效果没有显著的差异。

Abstract: Experiments in attraction of face fly Musca autumnalis De Geer females to ornamental plants Euonymus europaeus and E. kiautschovicus were conducted in the laboratory with Y-shaped glass olfactometer. The two plant species could attract face fly female adults, but E. europaeus was better in attraction of face flies than E. kiautschovicus. Female face flies responded more actively to odors of flowers of Euonymus plants than to odors of leaves, but leaves also played some roles in attraction when applied alone, and synergized the attraction of flowers when used together. Flowers of E. europaeus were extracted with several solvents, and the results showed that water or methanol extracts were better in attraction than hexane extracts. Frozen flowers showed similar attraction effects to fresh ones.
