Some aspects of the epidemiology of Maize streak virus (MSV) genus Mastrevirus concerning virus incidence, vector populations and some environmental factors were investigated in field experiments conducted over a three year period (2000–2002) at Samaru, northern Nigeria. Significant positive correlations were obtained between number of leafhoppers caught and MSV incidence and age of plant at infection and also with temperature. Also significant negative correlations were obtained between MSV incidence and mean relative humidity; between number of leafhoppers and age of plants and with mean rainfall. Leafhopper vectors caught included Cicadulina arachidis China, C. mbila Naude, C. triangula Ruppel and C. similis China, in order of abundance. Leafhopper incidence was highest in the months of September and October.

PL

W okresie trzech lat (2000–2003) w doświadczeniach polowych badano wybrane aspekty epidemiologii wirusa pasiastości kukurydzy (MSV) z rodzaju Mastervirus w tym nasilenie choroby, liczebność owadów-wektorów oraz wybrane czynniki środowiskowe. Stwierdzono istotną pozytywną korelację między liczbą odławianych skoczków, nasileniem infekcji MSV, wiekiem roślin i temperaturą powietrza. Natomiast istotnie negatywna korelację stwierdzono między nasileniem MSV i średnią wilgotnością powietrza, liczebnością skoczków, wiekiem roślin oraz poziomem opadów. Najwyższą liczebność skoczków obserwowano w miesiącach wrzesień–październik, a wśród nich stwierdzono Cicadulina arachidis China, C. mbila Naude, C. triangula Ruppe, and C. similis China, uszeregowane według liczebności w odłowach.
