“…Geographically, it was also distributed from the east (Sunsari district) to the west (Banke district) part of Nepal. Our results are similar to those found by Khatun et al [40]. They also detected ToLCNDV in three cryptic species (Asia I, Asia II 1, and Asia II 5) of B. tabaci that infested P. vulgaris, S. melongena, Dahlia sp., and S. lycopersicum.…”

“…Previously, Dolores and Valdez [39] detected this virus only in squash and pumpkin but not in cucumber and melon. Similarly, Khatun et al [40] detected this virus in B. tabaci collected from S. melongena and Nicotiana tabacum. However, we detected this virus in B. tabaci collected from C. pepo, C. sativus, S. edule, S. lycopersicum, and S. melongena.…”

“…This virus was detected in the Asia I, Asia II 1, and mostly from Asia II 5 species, which is the most abundant cryptic species of B. tabaci in Nepal [31]. In a previous study, Khatun et al [40] detected SLCCNV only in the Asia I species. Previously, Dolores and Valdez [39] detected this virus only in squash and pumpkin but not in cucumber and melon.…”

“…The Tomato leaf curl virus (ToLCV) is one of the most important economic viruses for solanaceous crops in Asia [25,[40][41][42][43][44]. In India, 21 different types of ToLCV were recorded [43].…”

“…The OELCuV virus was firstly identified in India and later in Pakistan, Bangladesh, Iran, and African countries [40,[47][48][49][50][51][52][53][54]. It caused severe disease in okra and an 80% yield loss in India [52].…”

The Bemisia tabaci species complex consists of at least 44 cryptic species, which are potential vectors of approximately 320 begomovirus species, most of which are significant plant viruses. However, the relationship of begomovirus transmission through vectors at the cryptic species level is uncertain. In our previous study, three cryptic species (Asia I, Asia II 1, and Asia II 5) of B. tabaci were identified from 76 B. tabaci samples collected across 23 districts in Nepal. Using the same individuals we identified seven different begomovirus species (Squash leaf curl China virus [SLCCNV], Tomato leaf curl New Delhi virus [ToLCNDV], Okra enation leaf curl virus [OELCuV], Synedrella leaf curl virus [SyLCV], Tomato leaf curl Kerala virus [ToLCKeV], Ageratum enation virus [AEV], and Tomato leaf curl Karnataka virus [ToLCKV]) by PCR using universal begomovirus primers. The begomoviruses were detected in 55.26% of whitefly samples, and SLCCNV was the most prevalent species (27.63%). Among the three cryptic species of B. tabaci, the virus detection rate was highest in Asia I (60%), followed by Asia II 1 (58.82%) and Asia II 5 (53.06%). Most viruses were detected in all three species, but AEV and ToLCKV were found only in Asia I and Asia II 1, respectively. Geographic analysis showed that SLCCNV was distributed in the whole country, which is similar to the distribution of the Asia II 5 species, but OELCuV and SyLCV were detected only in the middle region of Nepal. Our results provide important information on the begomovirus profile in Nepal which can be beneficial for plant virus risk assessment and develop the management strategies to reduce the damage of whitefly transmitted viruses.
