Plant viruses interact with their insect vectors directly and indirectly via host plants, and this tripartite interaction may produce fitness benefits to both the vectors and the viruses. Our previous studies show that the Middle East-Asia Minor 1 (MEAM1) species of the whitefly Bemisia tabaci complex improved its performance on tobacco plants infected by the Tomato yellow leaf curl China virus...

Transgenic Nicotiana tabacum plants expressing Aspergillus niger b-glucosidase (EC 3.2.1.21) gene (BGL1) in different subcellular compartments [cell wall (Tcw), endoplasmic reticulum (Ter), and vacuole (Tvc)] were analyzed to study the effects of BGL1 localization on plant growth and plant–insect interaction. Transgenic and non-transgenic plants were grown and characterized in a greenhouse with...

Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) is a cosmopolitan, highly polyphagous agricultural pest, which has the capacity to displace other native insect herbivores. Here, equipped with an integrated approach, effect of developmental stages and feeding density whiteflies on Myzus persicae performance in tobacco plants are investigated. Bioassay results showed that B. nymphs, but not adult...

The present study was carried out at the research field of Department Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh, during tomato (Solanum lycopersicum L.) growing seasons 2021 and 2022 to evaluate pest management benefit 4 insecticides, viz. Karate 2.5 ec (λ-cyhalothrin), Ripcord 10 (cypermethrin), Marshal 20 (carbosulfan), Shobicron 425 (profenofo...

Symbiotic relationships with bacteria are common within the Arthropoda, with interactions that substantially influence the biology of both partners. The symbionts' spatial distribution is essential for understanding key aspects of this relationship, such as bacterial transmission, phenotype, and dynamics. In this study, fluorescence in situ hybridization was used to localize five secondary symb...

Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) biotype B, also known as Bemisia argentifolii (Bellows et al., 1994), has been characterized as the main vector of begomoviruses, a virus genus that poses a major threat to the production of many vegetable crops worldwide (Polston & Anderson, 1997; Mansoor et al., 2003). Begomoviruses are transmitted by whiteflies in a persistent circulative manne...

UNLABELLED Tomato yellow leaf curl virus (TYLCV) is a begomovirus transmitted exclusively by the whitefly Bemisia tabaci in a persistent, circulative manner. Replication of TYLCV in its vector remains controversial, and thus far, the virus has been considered to be nonpropagative. Following 8 h of acquisition on TYLCV-infected tomato plants or purified virions and then transfer to non-TYLCV-hos...
