Cryptic species‐specific transmission of the invasive begomovirus tomato leaf curl New Delhi virus by the whitefly Bemisia tabaci

New Plant Protection, Volume 2, Issue 4, December 2025.
ToLCNDV is typically transmitted by the whitefly Bemisia tabaci, but the efficiency of transmission varies among different cryptic species. The retention and circulation of viruses in insect vectors are crucial determinants of successful transmission to new plants.

Genetic Diversity, Pathogenicity and Pseudorecombination of Cucurbit-Infecting Begomoviruses in Malaysia

Plants, 2021
Cucurbits are important crops in the world. However, leaf curl disease constrains their production. Here, begomovirus diversity and pathogenicity associated with the disease in Malaysia were studied based on 49 begomovirus-detected out of 69 symptomatic ...

Control of two sucking insect pests, a whitefly (Bemisia tabaci) and a thrips (Frankliniella occidentalis), infesting hot peppers by spraying LDH‐formulated dsRNA

Pest Management Science, Volume 81, Issue 12, Page 8163-8178, December 2025.
A vacuolar type ATPase subunit B (vATPase‐B) gene is identified and expressed in the midgut of Bemisia tabaci and Frankliniella occidentalis. The double‐stranded RNA (dsRNA) specific to vATPase‐B was expressed in hot peppers by virus‐induced gene silencing (VIGS) and killed both whitefly and thrips.

Characterization of Non-coding DNA Satellites Associated with Sweepoviruses (Genus Begomovirus, Geminiviridae) – Definition of a Distinct Class of Begomovirus-Associated Satellites [PDF]

Frontiers in Microbiology, 2016
Begomoviruses (family Geminiviridae) are whitefly-transmitted, plant-infecting single-stranded DNA viruses that cause crop losses throughout the warmer parts of the World. Sweepoviruses are a phylogenetically distinct group of begomoviruses that infect plants of the family Convolvulaceae, including sweet potato (Ipomoea batatas).

Groundnut Ringspot Orthotospovirus: An Emerging Problem for Soybean Production in São Paulo State

Plant Pathology, Volume 74, Issue 9, Page 2846-2856, December 2025.
Groundnut ringspot orthotospovirus is widely distributed in soybean fields in São Paulo State and is transmitted by thrips and, rarely, via seeds; it is a threat to soybean production with implications for virus spread and management. ABSTRACT Orthotospoviruses affect vegetable, leguminous and ornamental plants globally and are transmitted by thrips ...

Revision of Begomovirus taxonomy based on pairwise sequence comparisons [PDF]

Archives of Virology, 2015
Viruses of the genus Begomovirus (family Geminiviridae) are emergent pathogens of crops throughout the tropical and subtropical regions of the world. By virtue of having a small DNA genome that is easily cloned, and due to the recent innovations in cloning and low-cost sequencing, there has been a dramatic increase in the number of available ...

Twenty years of cucurbit breeding research at the World Vegetable Center

Crop Science, Volume 65, Issue 6, November/December 2025.
Abstract The contribution of cucurbit crops to global food and nutrition security is immense. They are economically and nutritionally important to smallholder farmers in Asia, who account for 81% of global cucurbit production. World Vegetable Center (WorldVeg) has been focused for 20 years on four species: bitter gourd (Momordica charantia), ridge ...
