Abstract
SUMMARY: Adult whiteflies (Bemisia tabaci) acquired the agent of cowpea golden mosaic (CGM‐A) within 7 min and transmitted during 2 min inoculation access. Nymphs also acquired CGM‐A and retained it through the pupal stage. Efficiency of transmission reached 90% when the acquisition period was increased to 36 h. The minimum latent period of CGM‐A in B. tabaci was 8 h, and the median latent period (LP50) about 12 h. Transmission was generally intermittent and declined throughout the period of 21 days which was the maximum time insects remained infective. Female whiteflies were more efficient vectors than males. B. tabaci acquired CGM‐A from plants inoculated only 60 h previously. The epidemiological implications of these findings are discussed.
