“…Viruses acquisition, retention and transmission in host plants belonging to different families are associated with the successful spread of the viruses. The whitefly-mediated transmission of cotton leaf curl virus to cotton plants showed that the least amount of time required to acquire the virus by whiteflies was 15 min to 4 h, while the least amount of time required to inoculate the plant was from 5 min to 1 h (Mann & Singh, 2004). Based on qPCR analysis, all three B. tabaci -complex species acquired CLCuMuV and CLCuMuB after a 6 h, 12 h, 24 h and 48 h AAP.…”

Cotton leaf curl Multan virus (CLCuMuV) is a serious and economically important viral disease agent in cotton and ornamental plants like Hibiscus in many regions of the world, especially in South Asia. CLCuMuV is transmitted exclusively by Bemisia tabaci cryptic species complex. This virus was recently recorded in southern China, presumably an invasion from South Asia. This study was performed to estimate the efficiency of three species of the B. tabaci whitefly complex (tentatively named as MEAM1, MED and Asia II 7, respectively) to transmit CLCuMuV and Cotton leaf curl multan virus betasatelite (CLCuMuB). Transmission assays and real-time quantitative PCR were conducted using three cultivars of cotton, Gossypium hirsutum, including 112-2, Xinhai-21 and Zhongmian-40. The results indicated that Asia II 7 was able to transmit the virus to two of the cotton cultivars, i.e. 112-2 and Xinhai-21, with the highest transmission efficiencies of 40% and 30%, respectively, but was unable to transmit the virus to the cotton cultivar Zhongmian-40. MEAM1 and MED failed to transmit CLCuMuV and CLCuMuB to any of the three cotton cultivars. After the three cryptic species of whiteflies had fed on virus-infected cotton plants for 48 h, the relative quantity of CLCuMuV in Asia II 7 was detected to be significantly higher than that in both MEAM1 and MED (P < 0.05). These results indicate that among the three species of whiteflies Asia II 7 is likely the most efficient vector for CLCuMuV and CLCuMuB in Malvaceae crops in China. Our findings provide valuable information to the control of viral diseases caused by CLCuMuV in the field.

“…Many studies have demonstrated that virus-infected host plants can affect the life parameters of insect vectors in different ways [14-17]. For instance, aphids fed on hosts infected with Potato leaf roll virus benefited from improved survival rate, fecundity, lifespan, and intrinsic rate of increase compared to those on healthy plants [14].…”

“…A population of the invasive tobacco whitefly, Bemisiatabaci , fed for 56 d on tobacco plants infected with Tomato yellow leaf curl China virus (TYLCCNV) or Tobacco curly shoot virus (TbCSV) increased faster in size, had 11–17 times higher fecundity, and a 5–6 times longer lifespan [15]. Conversely, the same insect fed on Cotton leaf curl virus -infected cotton leaves lived shorter lives and laid fewer eggs [16,17]. However, these previous studies did not analyze the causal factors of the changes in vector performance: the direct impact from insect viral infection and the indirect impact from virus-induced compositional changes in the diseased plants.…”

BackgroundSouthern rice black-streaked dwarf virus (SRBSDV) threatens rice production in China and Vietnam. The virus is vectored by the migrating white-backed planthopper (WBPH, Sogatella furcifera) in a circulative, propagative, and persistent manner. A persistently-transmitted plant virus might affect its vector’s development and fecundity directly by infecting the vector itself and/or indirectly altering the host plant. This study evaluated the direct and indirect effects of SRBSDV on WBPH performance to better understand the virus–vector–host plant relationship in terms of its effects on the biological parameters of the vector.MethodsThree experimental WBPH populations were established. Viruliferous and non-viruliferous populations were fed on SRBSDV-infected rice seedlings for 48 h as first-instar nymphs; infection status was confirmed by RT–PCR after they died. The control population was fed on healthy rice. Each insect was individually transferred to a healthy rice plant grown in a glass tube at 20°C, 25°C, or 28°C. Life parameters, including nymphal duration, survival rate, adult sex ratio, macropterous proportion, longevity, and oviposition amounts, of each population were measured at each temperature.ResultsThe life parameter data indicated that SRBSDV and infected rice plants adversely influenced WBPH; the effects were temperature dependent. Compared with the control population, viruliferous populations showed significant changes, including prolonged nymphal stages and reduced survival rates at 20°C, while the non-viruliferous population had higher survival rates at 20°C and lower rates at 28°C compared with the control. Both populations had significantly shorter adult life spans at 25°C and lower oviposition amounts at 28°C relative to the control.ConclusionsBoth SRBSDV-infection and feeding on infected rice plants affected vector performance. Although a longer nymphal period benefits viral acquisition and transmission by nymphs and might increase rice infection rate, in general, SRBSDV infection of the vectors and host plants was unfavorable to WBPH population expansion.

“…Evidence currently indicates that the relationships between a virus and vector can be either mutualistic 23 24 or antagonistic 25 26 , and the virus may affect the vector’s physiology and behavior to influence its likelihood of transmission 27 28 29 30 31 . Nevertheless, the lack of comprehensive and integrated consideration of vector physiology and behavior after virus infection has limited our understanding of the evolutionary significance and mechanisms underlying their interactions.…”

Virus-vector relationships can be complex and diverse as a result of long-term coevolution. Understanding these interactions is crucial for disease and vector management. Rice stripe virus (RSV) is known to be transovarially transmitted within its vector, Laodelphax striatellus, and causes serious rice stripe disease. In RSV-infected L. striatellus, we found contrasting changes in vector fecundity, physiology, primary endosymbionts (i.e. yeast-like symbionts, YLS) and feeding behavior that can interact to affect the spread of RSV. RSV-infected L. striatellus exhibited a significant decrease in fecundity that could lead a reduction of viruliferous individuals in populations. As a potential response to this loss, RSV infection also significantly shortened nymphal stage duration, which can strengthen RSV vertical circulation in L. striatellus populations and promote RSV spreading by adult migration and dispersal. Down-regulated JHAMT and up-regulated CYP307A1 in the juvenile hormone and ecdysteroid pathways, respectively, were linked to accelerated development. RSV-infected adults were also found to have higher body weight in conjunction with increased YLS abundance. Furthermore, prolonged host plant phloem exposure to salivation by RSV-infected adults should further enhance RSV horizontal transmission. Our study highlights potential strategies of RSV in enhancing its transmission, and provides new insights into the complexity of virus-vector interactions.
