摘要: 反-β-法尼烯(EβF)是蚜虫报警外激素的主要组分,可以驱避蚜虫并调节部分天敌的行为反应.为明确其生态功能,研究了EβF对马铃薯田间蚜虫(桃蚜、棉蚜、马铃薯长管蚜)及其主要天敌种群数量变动的影响.结果表明: 2年内,EβF处理区(每周100 μL)植株上的蚜虫数量显著低于对照区,瓢虫(2012、2013年)及僵蚜(2012年)的数量显著高于对照区.2012年,距离EβF释放器1和5 m处植株上蚜虫数量显著低于10 m处;2013年,距离EβF释放器1 m处植株上蚜虫数量显著低于5及10 m处.EβF处理区黄盆内寄生蜂和食蚜蝇(2012年)以及瓢虫(2013年)的数量显著高于对照区.表明马铃薯田间释放EβF可以在一定距离范围内抑制蚜虫的种群增长.

Abstract: As a most common component of aphid alarm pheromone, E-β-farnesene (EβF) could not only dispel aphids, but also modify some behavioral responses of their natural enemies. In order to investigate the ecological function of EβF, its influence on the population dynamics of Myzus persicae (Sulzer), Aphis gossypii (Glover), Macrosiphum euphorbiaein (Thomas) and their natural enemies was studied in potato fields. The results showed that there were significantly lower aphid abundance (2012, 2013), higher ladybird beetle abundance (2012, 2013), and higher mummified aphid abundance (2012) on potato plants in EβF treated plots (100 μL per week). The numbers of aphids at the distances of 1 m and 5 m from EβF releaser were significantly lower compared to 10 m in 2012, and the aphid number was significantly lower at the distance of 1 m compared to 5 m and 10 m in 2013. Moreover, significantly higher parasitoid and hoverfly numbers in 2012 and higher numbers of ladybird beetles in 2013 were observed in yellow traps in EβF treated plots. The results suggested that EβF could suppress aphid population growth within a certain distance in potato fields.

Key words: aphid, E-β-farnesene, population dynamic, natural enemy, biological control.
