| description | Viruses that cause tomato yellow leaf curl disease are part of a group of viruses of the genus <i>Begomovirus</i>, family <i>Geminiviridae</i>. Tomato-infecting begomoviruses cause epidemics in tomato crops in tropical, subtropical, and Mediterranean climates, and they are exclusively transmitted by <i>Bemisia tabaci</i> in the field. The objective of the present study was to examine the transmission biology of the tomato yellow leaf curl Thailand virus (TYLCTHV) by <i>B. tabaci</i>, including virus-infected tissues, virus translocation, virus replication, and transovarial transmission. The results demonstrated that the virus translocates from the alimentary gut to the salivary glands via the hemolymph, without apparent replication when acquired by <i>B. tabaci</i>. Furthermore, the virus was detected in 10% of the first-generation progeny of viruliferous females, but the progeny was unable to cause the viral infection of host plants. There was no evidence of transovarial transmission of TYLCTHV in <i>B. tabaci</i>. When combined with the current literature, our results suggest that <i>B. tabaci</i> transmits TYLCTHV in a persistent-circulative mode. The present study enhances our understanding of virus–vector interaction and the transmission biology of TYLCTHV in <i>B. tabaci</i>. |
