中文摘要:
      豇豆轻斑驳病毒(Cowpea mild mottle virus,CPMMV)的流行与其媒介昆虫烟粉虱Bemisia tabaci密切相关,但CPMMV感染寄主植物对B型烟粉虱寄主选择行为和生物学特性的影响尚不清楚。本研究探究了1)CPMMV感染菜豆Phaseolus vulgaris不同时间对B型烟粉虱寄主选择和产卵偏好性的影响;2)CPMMV感染菜豆对B型烟粉虱生物学特性的影响。结果发现:1)相较于健康菜豆,摩擦接种CPMMV后1周,B型烟粉虱却偏好在CPMMV感染的植株上停留和产卵;而摩擦接种后4周,B型烟粉虱却偏好在健康的植株上停留和产卵;2)无论是在摩擦接种后1周和4周的CPMMV感染植株上,B型烟粉虱在健康和CPMMV感染植株上的产卵量和存活率差异不明显。可见,CPMMV感染菜豆对于B型烟粉虱的寄主选择偏好性具有时间效应,而CPMMV感染菜豆对于B型烟粉虱的生物学特性没有显著影响。
英文摘要:
      The epidemiology of Cowpea mild mottle virus(CPMMV) is closely associated with its vector whitefly, Bemisia tabaci B biotype. However, the effects of CPMMV infection of host plant on host selection and biological characteristic of B. tabaci B biotype remain unexplored. In this study, we analyzed: 1) the effect of CPMMV infection of Phaseolus vulgaris at different time points on host selection and oviposition preference of B. tabaci B biotype; 2) the effects of CPMMV infection on biological characteristic of B. tabaci B biotype. Our results showed that: 1) compared with healthy P. vulgaris, B. tabaci B biotype preferred to stay and lay eggs on CPMMV-infected P. vulgaris. However, for the experiment conducted on the four weeks old plants after CPMMV inoculation, B. tabaci B biotype preferred to stay on healthy plants and lay eggs; 2) B. tabaci B biotype had no difference in fecundity and survival rates between healthy and CPMMV-infected plants at 1 and 4 weeks after CPMMV inoculation. In conclusion, CPMMV infection of P. vulgaris had a time effect on the host preference of B. tabaci B biotype, but CPMMV infection of P. vulgaris had no significant effect on the biological characteristics of B. tabaci B biotype.
