“…Particularly, shortening of the vector lifespan was observed in both the immature and adult stages. Previously, reduction of adult longevity was reported in B. tabaci infected by TYLCV or Cotton leaf curl virus (CLCuV) (Rubinstein and Czosnek, 1997;Mann et al, 2008;Sidhu et al, 2009). Similar effects of plant viruses have also been reported in other insects.…”

“…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.

“…However, in Jiu et al (2007) the asymmetry between the two biotypes was expressed in a totally different manner: infection of host plant by a begomovirus, either TYLCCNV + DNAβ or TbCSV+ DNAβ, improved the performance of the B biotype substantially but had no effects on the ZHJ1 biotype. Several studies have been reported from the USA to examine the effects of virus infection of host plants on the performance of B. tabaci , although the experiments on the alien invasive B biotype and the indigenous A biotype were conducted separately (Cohen et al, 1983; Costa et al, 1991; McKenzie, 2002; McKenzie et al, 2002; Mann et al, 2008; Polton & Toapanta, 2008). These reports indicate that infection of host plants by a begomovirus may exert beneficial, neutral or negative effects on the B biotype depending on the species of viruses and host plants but usually neutral or negative effects on the A biotype.…”

“…In the literature, a number of studies have addressed the effects of virus infection of host plants on the performance of various biotypes of B. tabaci and have demonstrated a range of outcome (Colvin et al, 2006). Compared to its performance on uninfected plants, the B biotype feeding on begomovirus‐infected plants performed better (McKenzie, 2002; McKenzie et al, 2002), similarly (Lapidot et al, 2001; Mann et al, 2008), or less well (Lapidot et al, 2001; Polston & Toapanta, 2008). In addition, virus infection of the B biotype per se could reduce the whitefly's longevity and fecundity (Rubinstein & Czosnek, 1997; Jiu et al, 2007).…”

The role of vector-begomovirus-plant interactions in the widespread invasion by some members of the whitefly species complex Bemisia tabaci is poorly understood. The invasive B biotype of B. tabaci entered China in the late 1990s and had become the predominant or only biotype of the whitefly in many regions of the country by [2005][2006]. Meanwhile epidemics of begomoviruses have been observed in many crops including tomato for which Tomato yellow leaf curl China virus (TYLCCNV) and Tomato yellow leaf curl virus (TYLCV) have been identified as two major disease-causing agents. Here, we conducted laboratory experiments to compare the performance of the invasive B and indigenous ZHJ1 whitefly biotypes on uninfected, TYLCCNV-infected and TYLCV-infected plants of tomato cv. Hezuo903, a cultivar that has been widely cultivated in many regions of China. The infection of tomato plants by either of the viruses had no or only marginal effects on the development, survival and fecundity of the B biotype. In contrast, survival and fecundity of the ZHJ1 biotype were significantly reduced on virus-infected plants compared to those on uninfected plants. Populations of the B biotype on uninfected and TYLCCNV-infected plants increased at similar rates, whereas population increase of the ZHJ1 biotype on TYLCCNV-infected plants was affected adversely. These asymmetric responses to virus infection of tomato plants between the B and ZHJ1 biotypes are likely to offer advantages to the B biotype in its invasion and displacement of the indigenous biotype.
