This species is a vector of striate mosaic virus of grasses and cereals in Australia. Grylls (327) was first to report this species as a vector of this virus in 1963. Transmission was effected to eight varieties of wheat, three of oats, and two of barley. Three species of grasses (Chloris gayana Kunth, Ixophorus unisetus (Presl) Schlecht., Dactylis glomerata L.) and (Zea mays L.) were experimentally infected. The minimum total incubation period in the vector and host plant (C. gayana) was about 8 days. The virus was more efficiently transmitted from plant to plant of the same species than from plant to plant of different species. The virus was transmitted by nymphs as well as adults. The percentage of leafhoppers as vectors was 60. Attempts to pass the virus transovarially proved negative.
This species has potential as an important vector in the natural spread of the virus in commercial crops of grain. At present it does not cause extensive losses owing to lack of populations during the most susceptible stage of plant growth. Populations of leafhoppers were greatest when the grain was almost mature. The species has greater importance in the spread of virus to grasses in pasture lands and rangelands.
Small, linear species. male 3.10—3.60 mm., female 3.20—3.60 mm.
Pygofer in lateral aspect slightly longer than wide, caudoventral margin produced posteriorly to small fingerlike lobe; aedeagus in lateral aspect simple, broad basally, attenuated apically to narrow sharp point, tubelike in ventral aspect; gonopore large, terminal, arising from ventral surface of shaft; style in dorsal aspect simple, apex narrowed, curved laterally; female seventh sternum with caudal margin nearly truncate.
is the only reported species in the genus
that is a vector.
