摘要

Bemisia tabaci is a global species complex consisting of at least 40 cryptic species. It is also a vector for at least 100 species of begomovirus, many of which cause severe crop damage. The relationship between begomoviruses and cryptic species of the B. tabaci species complex, however, remains unclear. Our previous study [13] was identified four cryptic species (Asia I, Asia II 1, Asia II 5, and Asia II 10) of B. tabaci from Bangladesh. Using those 110 whitefly samples, vector-based PCR analysis identified 8 different begomovirus species: BYVMV, BGYVV, OELCV, SLCCV, SLCV, TbCSV, ToLCBV, and ToLCNDV. The overall rate of virus infection was 26.4%, and BYVMV and ToLCNDV were the most frequently detected in the B. tabaci vector. Virus infection rates for Asia I, Asia II 1, Asia II 5, and Asia II 10 were 22.4% (15/67), 35% (7/20), 27.3% (6/22), and 100% (1/1), respectively. Each cryptic species infected multiple virus species, but SLCCV, TbCSV, and BGYVV were each only detected in, Asia I, Asia II 1, and Asia II 5, respectively. This study demonstrates the geographic distribution of various begomoviruses in Bangladesh and their relationships with cryptic species of B. tabaci.

Tabaci的四种神秘物种（亚洲I，亚洲II 1，亚洲II 10）。使用这些110粉虱样品，基于载体的PCR分析确定了8种不同的原绒毛血管物种：BYVMV，BGYVV，OELCV，SLCCV，SLCV，TBCSV，TOLCBV和TOLCNDV。病毒感染的总体速率为26.4％，并且在B. tabaci载体中最常检测到ByVMV和TolcNDV。亚洲I，亚洲I亚洲的病毒感染率为22.4％（15/67），35％（7/20），27.3％（6/22）和100％（1 / 1）分别。每种神秘的物种都感染了多种病毒物种，但SLCCV，TBCSV和BGYVV分别分别检测到，亚洲I，亚洲II 1和亚洲II 5。本研究展示了孟加拉国各种原毛病的地理分布及其与B塔布的神秘种类的关系。
