The infection of leafhoppers by western X-disease virus

摘要: Abstract Western X-disease virus (WXV) was transmitted to healthy Colladonus montanus Van Duzee by injection of hemolymph or clarified extracts from infected vectors. Virus first celery 11–14 days after the insects were injected with infectious hemolymph. The inoculativity vectors all inocula reached a peak, then declined rapidly. When tenfold dilutions extract injected, position transmission curve for each dilution respect time scale function concentration. latent period in vector and peak therefore extended when injected. Transmission curves obtained leafhoppers acquiring WXV feeding on diseased similar those 10 −3 Percentages transmitting 2- 4-day inoculation access periods could be converted single-day percentages binomial probability calculations.
