“…Differences in whitefly preference have been reported among common bean cultivars (Jesus et al 2010;Pinheiro et al 2014;Silva et al 2014). In our trials, fewer adult whiteflies were observed on some genetically modified elite lines and conventional cultivars, which may have resulted in fewer nymphs and virus-infected plants.…”

In Brazil, the Cowpea mild mottle virus vectored by Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae), is an emerging threat for common bean (Phaseolus vulgaris L.; Fabaceae), including genetically modified elite bean lines developed for resistance to the Bean golden mosaic virus. To investigate this interaction, we quantified the susceptibility of 10 Bean golden mosaic virus-resistant lines to Cowpea mild mottle virus infection in 2 regions in Brazil with natural incidence of viruliferous B. tabaci. In 2 field trials, B. tabaci established on all varieties, but showed preference for the conventional cultivars 'Pérola' and 'BRS Pontal' when compared with elite lines (averaging > 400 nymphs per leaflet, and > 97% infection rate in 1 study). However, whereas elite lines were resistant to Bean golden mosaic virus, all became infected with Cowpea mild mottle virus. Highest infection rates (19 to 99% infected plants) occurred in genetically modified elite lines derived from BRS Pontal versus Pérola (12 to 16%). When comparing seed yield, most elite lines outperformed their conventional recurrent parent. On average, elite lines achieved relative yield increases between 199 and 1,045%, and the varieties CNFCT 16205 and CNFCT 16210 were the most productive in our field trials. Our results showed that the use of common bean cultivars resistant to golden mosaic is an important tool within integrated management strategies for whiteflies and viruses. However, further studies are needed to elucidate the threat of Cowpea mild mottle virus and the nature of whitefly interactions between these different viruses.

“…In such instances, the virus needs to survive on the surface under certain environmental conditions. Some studies have demonstrated that temperature and humidity are significantly correlated with viral survival and transmission rates on surfaces (Harper, 1961;Metz and Finn, 2015;Pinheiro et al, 2014;Wang et al, 2020). Additionally, recent reports have shown that sunlight could rapidly inactivate airborne SARS-Cov-2 (Schuit et al, 2020;Dabisch et al, 2020;Smither et al, 2020).…”

“…It was reported that the outbreak of SARS in Guangdong, China in 2003 gradually diminished as the weather became warmer and ended by July, indicating that temperature variations might have affected the outbreak (Tan et al, 2005;Wallis and Nerlich, 2005). Moreover, humidity has also been found to be significantly correlated with viral survival and transmission rates (Pinheiro et al, 2014). COVID-19, which is similar to SARS but caused by a different coronavirus, was first reported in China (Wu et al, 2020).…”

“…Risk assessment studies also have to investigate whether transgenic disease resistance can affect the ecosystem. In one example, arthropod populations on transgenic beans expressing a virus replication gene were compared with those on nontransgenic plants (Pinheiro et al, 2014). In another study, transgenic disease-resistant wheat was tested for effects on dipterans (Peter et al, 2010) and colonization by root microbes (Meyer et al, 2013).…”

Plant diseases are responsible for major crop losses and postharvest spoilage; though losses are difficult to calculate, educated estimates suggest they are responsible for 20% to 40% of losses from plough to plate for major crops (Oerke, 2006;Savary et al., 2019). Hypothetically, with current estimated population growth, we could solve the challenge of feeding the world by 2050 were we able to control all disease (Collinge et al., 2010). Plant disease can be managed primarily by farmer skill, pesticides, disease resistance, and biological control, in roughly that order of importance. Disease resistance is effective when it works because no specific input is required by the grower after sowing or planting. However, despite major effort by plant pathologists and breeders over a century, no effective disease-resistant cultivars are available for many diseases, and, for many important diseases, the pathogen overcomes natural
