Summary: This study discovered a new method to prevent the transmission of Tomato chlorosis virus by using the new pesticide pyrifluquinazon, which can effectively reduce the ability of whitefly to transmit the virus. This finding is of great significance for controlling tomato yellow leaf disorder.

Summary: Insect pollination is a vital process for the natural ecosystem and crop reproduction. Bumblebees, especially Bombus terrestris, are widely used pollinators for crops such as tomato. The efficiency of bee pollination is influenced by various factors, including bee species, plant nutrition, and herbivores like Bemisia tabaci. This study found that B. terrestris preferred tomato plants damaged by B. tabaci, and identified specific plant volatiles induced by B. tabaci that significantly attracted B. terrestris.

Summary: Bemisia tabaci, also known as whitefly, is a vector for over 200 plant viruses including Tomato chlorosis virus (ToCV). Targeting the trehalase enzyme in whiteflies can reduce ToCV transmission efficiency, as shown by the inhibitory effects of validamycin on trehalase activity and whitefly physiology.

Summary: The study found that B. tabaci exhibits an aggregated distribution in tomato fields with a strong spatial dependence. Overall, the densities of adults and nymphs are higher at the field edges and reach economic thresholds. The results suggest a colonization pattern for B. tabaci starting at the edges and spreading inwards in tomato fields, which can improve management strategies.

Summary: Flavonoids in plants have been shown to have pleiotropic effects in defense against abiotic and biotic stresses. This study investigated whether seed priming with rutin, a type of flavonoid, can enhance tomato resistance against the whitefly. The results showed that rutin seed treatment reduced the developmental rate and feeding efficiency of the whitefly, and was associated with increased flavonoid accumulation and expression of defense genes. These findings suggest that seed treatment with rutin can prime tomato resistance against the whitefly without affecting shoot growth.

Summary: The study demonstrated that ToCV infection significantly increases the fecundity of the sweet potato whitefly B. tabaci MED, mainly through the elevated expression of the vitellogenin gene (Vg). When Vg expression was suppressed, ovarian development and fecundity of the whitefly were inhibited, regardless of ToCV infection.

Summary: Transmission parameters of ToLCNDV-ES differ between zucchini and tomato plants, with significantly higher transmission efficiency in zucchini. This may explain the different incidences of ToLCNDV-ES in zucchini and tomato crops in Spain. The results are also important for virus management and the trade and transport of infected plant material.

Summary: This study compares the ingestion and egestion of yellow vein mosaic virus and okra enation leaf curl virus by two cryptic species of whitefly. The results show that both species of whitefly can acquire the viruses within a short feeding time, but the amount of ingestion varies. Different genetic groups of whitefly acquire different types and quantities of virus after 24 hours of feeding. Asia I is found to be a more effective transmitter of okra enation leaf curl virus, while Asia II 5 is a more effective transmitter of yellow vein mosaic virus.

Summary: The BtILP7 gene, highly expressed in ToCV-infected whiteflies, was found to be closely related to ToCV transmission by regulating trehalose metabolism and reproductive behavior. Targeting this gene provides an environmentally friendly strategy to control whiteflies and ToCV-caused disease.

Summary: The study finds that the use of spirotetramat can optimize the management of B. tabaci and ToCV by reducing the attractiveness of infected plants to whiteflies and increasing whiteflies' ability to transmit the virus.

Summary: The Mi-1 gene in tomato provides resistance against nematodes and insects, but the resistance mechanisms differ depending on the harmful organism. The Hsp90 gene has been shown to be involved in the Mi-1-mediated resistance for nematodes and aphids, but its role in resistance to whiteflies was unclear. This study demonstrates that the Hsp90 gene is required for the Mi-1-mediated resistance to whiteflies, supporting the hypothesis of a common model for resistance against nematodes and insects.

Summary: Agricultural landscape pattern plays a crucial role in enhancing biocontrol services by supporting the population of parasitoid species, including those that control Bemisia tabaci. This study found that flower fields and mountain landscapes were the most favorable habitats for parasitoids, with higher parasitism rates and lower B. tabaci populations compared to other landscape types. Increasing the size of flower fields in agricultural landscapes can enhance the sustainable control of B. tabaci by promoting the activity of natural enemies.

Summary: This study examines the direct and indirect effects of two prevalent begomoviruses, Tomato yellow leaf curl Thailand virus (TYLCTHV) and Tomato leaf curl Taiwan virus (ToLCTV), on the sweet potato whitefly (Bemisia tabaci). The results show that TYLCTHV has no effects on the whitefly, while ToLCTV negatively affects its fecundity and nymph developmental time, and alters its feeding preference. The different effects of virus infection may contribute to the lower prevalence of ToLCTV compared to TYLCTHV in fields in Taiwan.
