番茄黄化曲叶病毒对B型和Q型烟粉虱雌虫体长及卵大小的影响

Effect of Tomato Yellow Leaf Curl Virus on Female Body Length and Egg Size of Bemisia tabaci Biotypes B and Q

本试验比较了携带番茄黄化曲叶病毒(Tomato yellow leaf curl virus,TYLCV)与未携带TYLCV的B型和Q型烟粉虱的雌虫体长以及其在健康番茄苗上所产卵的长度和宽度,以探讨B型和Q型烟粉虱对TYLCV的适应性差异,进而探讨TYLCV在B型和Q型烟粉虱竞争取代过程中的作用。结果表明:带毒的B型和Q型烟粉虱雌虫体长与无毒的B型和Q型烟粉虱均无显著差异;带毒B型烟粉虱所产卵的长度和宽度分别显著大于无毒B型烟粉虱,而带毒Q型烟粉虱所产卵的长度和宽度分别显著小于无毒Q型烟粉虱。TYLCV对B型和Q型烟粉虱的雌虫体长无显著影响,而对所产卵的大小有显著影响。

The infection of Tomato yellow leaf curl virus(TYLCV)have influence on the biological characteristics of Bemisia tabaci.The differences in female body length,and length and width of eggs ovipositied by viruliferous and non-viruliferous B. tabaci B and Q biotypes were compared.The results indicated that there was no significant difference in female body length between viruliferous B and Q biotypes B. tabaci and non-viruliferous B and Q biotypes,respectively.The length and width of eggs oviposited by viruliferous B biotype B. tabaci were significantly larger than that oviposited by non-viruliferous B biotype,respectively.However,the length and width of eggs oviposited by viruliferous Q biotype B. tabaci were significantly smaller than that oviposited by non-viruliferous Q biotype,respectively.Therefore,the egg size of B and Q biotypes B. tabaci responded differently to TYLCV,whereas no impact for female body length.
