Transmission of Tomato spotted wilt virus by Frankliniella occidentalis; median acquisition and inoculation access period
Annals of Applied Biology 129 (2), 303-313
Abstract: To quantify the transmission of tomato spotted wilt virus (TSWV) by Frankliniella occidentalis, the median acquisition access period (AAP₅₀) and median inoculation access period (IAP₅₀) were determined. These parameters were established using transmission rates obtained after AAPs and in IAPs which both ranged from 5 to 2560 min. An AAP₅₀ of 106 min was found when larvae acquired virus from TSWV-infected Impatiens plants. IAP₅₀s of 58 or 137 min, respectively, were calculated when, petunia or Datura stramonium leaf disks were used to test the inoculation efficiency of viruliferous thrips. The virus could successfully be acquired or inoculated in periods of 5 min. Transmission reached an optimum after an AAP of 21.3 h (AAP_opt) and in an LAP of 42.7 h (IAP_opt). These results show that TSWV can be acquired and transmitted efficiently by F. occidentalis in short feeding periods.
