摘　　要：为探索芹菜Apium graveolens对烟粉虱Bemisia tabaci的防控机理,以盆栽芹菜和辣椒Capsicum annuum为试材,以不同密度进行间作,分析间作芹菜对辣椒上烟粉虱的发育历期和存活率以及辣椒叶片中抗烟粉虱相关物质含量的影响。结果表明,间作芹菜对辣椒上烟粉虱若虫的发育历期和存活率有显著影响,芹菜密度越大,辣椒上烟粉虱若虫的发育历期越长,存活率越低,当辣椒与芹菜以2∶1、2∶2和2∶3的密度间作时,辣椒上烟粉虱从卵到伪蛹的发育历期分别较对照显著延长了5.47%、9.76%和16.64%,存活率分别较对照降低了20.85%、16.65%和54.15%。间作芹菜对辣椒体内抗烟粉虱相关生化物质的含量也存在显著影响,芹菜间作密度越大,辣椒叶片中可溶性糖、类黄酮和总酚的含量越高,脯氨酸含量则呈下降趋势,当辣椒与芹菜以2∶1、2∶2和2∶3的密度间作10 d后,辣椒叶片中脯氨酸含量分别较对照显著降低了20.23%、19.72%和29.98%,可溶性糖含量分别较对照升高了23.92%、30.20%和37.25%,类黄酮含量分别较对照升高了15.70%、24.92%和27.08%,总酚含量含量分别较对照升高了36.80%、30.40%和8.80%。表明间作芹菜可以引起辣椒叶片中抗烟粉虱相关物质含量的变化,进而有利于增强辣椒对烟粉虱的抗生性。In order to further explore the control mechanism of celery Apium graveolens on the whitefly Bemisia tabaci,the effects of intercropping with celery on the development and survival of whiteflies on pepper plants and the whitefly-resistant metabolites in pepper leaves were investigated.The results showed that intercropping with celery affected the developmental duration and the survival rate of whiteflies on pepper plants.With increasing density of celery,the nymph survival rate and the developmental duration increased.When the ratios of pepper∶celery were 2∶1,2∶2,and 2∶3,the developmental duration from egg to pseudopupa on pepper plants was significantly increased by 5.47%,9.76%,16.64%,and the whitefly survival rate was decreased by 20.85%,16.65%,54.15%,respectively.Intercropping with celery also had effects on the metabolites unfavorable to whiteflies.After ten days of intercropping,the proline content was decreased by 20.23%,19.72%and 29.98%;the soluble sugar content was increased by 23.92%,30.20%and 37.25%;the flavonoid content was increased by 15.70%,24.92%and 27.08%,and the total phenol content was increased by 36.80%,30.40%and 8.80%,respectively,compared with the control.These results indicate that celery intercropping could alter the content of metabolites in pepper leaves,which might affect whitefly development.
