“…Both direct and indirect effects of the pathogen on the vector, or vice versa, can be beneficial or harmful, depending on the species [1]–[4]. For example, studies of the indirect effects of viruses on their vectors have revealed a variety of outcomes, ranging from positive [2], [5]–[10], neutral [11], [12], to negative [13], [14]. While the effects of these interactions on individual pathogens and herbivores are often quantified, the consequences of these interactions for the population dynamics of both types of organisms and the evolution of ecological communities have rarely been studied.…”

Vector-Virus Mutualism Accelerates Population Increase of an Invasive Whitefly

The relationships between plant viruses, their herbivore vectors and host plants can be beneficial, neutral, or antagonistic, depending on the species involved. This variation in relationships may affect the process of biological invasion and the displacement of indigenous species by invaders when the invasive and indigenous organisms occur with niche overlap but differ in the interactions. The notorious invasive B biotype of the whitefly complex Bemisia tabaci entered China in the late 1990s and is now the predominant or only biotype in many regions of the country. Tobacco curly shoot virus (TbCSV) and Tomato yellow leaf curl China virus (TYLCCNV) are two whitefly-transmitted begomoviruses that have become widespread recently in south China. We compared the performance of the invasive B and indigenous ZHJ1 whitefly biotypes on healthy, TbCSV-infected and TYLCCNV-infected tobacco plants. Compared to its performance on healthy plants, the invasive B biotype increased its fecundity and longevity by 12 and 6 fold when feeding on TbCSV-infected plants, and by 18 and 7 fold when feeding on TYLCCNV-infected plants. Population density of the B biotype on TbCSV- and TYLCCNV-infected plants reached 2 and 13 times that on healthy plants respectively in 56 days. In contrast, the indigenous ZHJ1 performed similarly on healthy and virus-infected plants. Virus-infection status of the whiteflies per se of both biotypes showed limited effects on performance of vectors on cotton, a nonhost plant of the viruses. The indirect mutualism between the B biotype whitefly and these viruses via their host plants, and the apparent lack of such mutualism for the indigenous whitefly, may contribute to the ability of the B whitefly biotype to invade, the displacement of indigenous whiteflies, and the disease pandemics of the viruses associated with this vector.

“…In addition, both the tospovirus species themselves and their various isolates also play an important role in determining the thrips vector competence (being viruliferous or non‐viruliferous) (Wijkamp et al. 1995; Roca et al. 1997; Nagata et al.…”

“…Finally, virus induced physiological or morphological changes of the host plant will obviously affect choice behaviour and development as well as subsequent virus transmission by any thrips population (Wijkamp et al. 1995; Roca et al. 1997).…”

The thrips Ceratothripoides claratris is an efficient vector of the Capsicum chlorosis virus (CaCV). Transmission studies with a natural population of C. claratris found in a greenhouse ‘GH’ and a ‘colony’ derived from this ‘GH’ population by selection and inbreeding resulted in lowering the percentage of viruliferous individuals within the ‘colony’. After passing through approximately 20 generations, the ‘colony’ lost the ability to transmit the CaCV. When either viruliferous or non‐viruliferous virgin females reproduced parthenogenetically, 81% of F1 arrhenotokous males inherited their viruliferous status from their mothers, whilst, no viruliferous offspring arose from non‐viruliferous virgin mothers. Crosses between viruliferous and non‐viruliferous individuals suggest that the competence of the thrips C. claratris as a vector for this virus is probably a heritable trait controlled by a recessive allele.

Herbivore arthropods benefit from vectoring plant viruses

et al. 2004

Plants infected with pathogens often attract the pathogensÕ vectors, but it is not clear if this is advantageous to the vectors. We therefore quantified the direct and indirect (through the host plant) effects of a pathogen on its vector. A positive direct effect of the plant-pathogenic Tomato spotted wilt virus on its thrips vector (Frankliniella occidentalis) was found, but the main effect was indirect; juvenile survival and developmental rate of thrips was lower on pepper plants that were damaged by virus-free thrips than on unattacked plants, but such negative effects were absent on plants that were damaged and inoculated by infected thrips or were mechanically inoculated with the virus. Hence, potential vectors benefit from attacking plants with virus because virus-infected plants are of higher quality for the vector's offspring. We propose that plant pathogens in general have evolved mechanisms to overcome plant defences against their vectors, thus promoting pathogen spread.
