Hello K, I know that virus can only be transmitted by western flower thrip by the larvae, not the flying critters. Feeding habit and the mechanics of their feeding could make a difference in whether or not a particular bug could transmit a virus. Other thrips could also spread the virus as well, but if the author doesn't know about it or is only providing details about that particular bug, they wouldn't include that information, possibly. All I know is that thrip are a giant pain the whatoosie when they get resistant.... at one point there was a population that was resistant to orthene fogging.... luckily they are not resistant to a greenhouse that has had the heat turned off and winter temperatures allowed to clean things up. -- charles ufford oriskany, ny usa _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
