Comparison of transmission abilities of four Cicadulina species vectors of maize streak virus from Nigeria por Oluwafemi, S., Jackai, L.E.N., Alegbejo, M.D.

“…The transmission efficiencies of these vectors increased with longer feeding periods, as the means of susceptible test plants that showed Mastrevirus symptoms for both acquisition and IAPs were higher for 24 and 48 h than for 1 and 2 h for all four species studied. The epidemiological implications of these differences in transmission abilities are discussed.…”
