Two Thrips tabaci populations were tested for their ability to transmit a Tomato spotted wilt virus (TSWV) isolate from South Bulgaria (GD07) originating from tobacco. The thelytokous population originated from leek and the arrhenotokous population from tobacco. The two populations were analyzed separately under laboratory conditions and the offspring of unmated females of each population were tested. The transmission efficiency of adult T. tabaci was tested with petunia leaf disc assays. The investigation showed that the thelytokous population and the resulting offspring, which also consisted of females, were not able to transmit the TSWV isolate. The arrhenotokous population and its offspring differed in transmission efficiency of GD07. The transmission rate of the arrhenotokous population was about 20%, with male individuals exhibiting higher transmission rate than females. The offspring of the arrhenotokous population, consisting only of males, transmitted TSWV GD07 with 93% efficiency.
