Abstract：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．
