Preliminary evidence of recovery from Tomato spotted wilt virus infection in Frankliniella occidentalis individuals
Annals of Applied Biology 161 (3), 266-276
Abstract: In this study we analysed the ability of individual thrips to transmit Tomato spotted wilt virus (TSWV) in a population of Frankliniella occidentalis over their lifespan as adults (about 10 days). In three experiments a total of 636 thrips were individually tested for their transmission capacity through leaf disc assays using four inoculation access periods (IAPs). Almost half of the transmitting thrips maintained the capacity to infect leaf discs in each of the four IAPs, confirming the persistent propagative nature of the transmission modality. Nevertheless, a relevant number of thrips (9.25% of transmitter thrips) was able to transmit in the early phases of their adult life (for the first two IAPs), but did not transmit the virus for the remainder of their lifetime. We compared the virus titer of these individuals at the end of the fourth IAP with that of individuals that maintained transmission ability in the four IAPs and showed a statistically significant difference. This difference could be evidence for recovery from TSWV infection in individual thrips.
