|Crops Affected by Cicadulina parazeae Ghauri 1961a: 369|
This species is a vector of maize streak virus in Rhodesia. Ghauri in 1961 (307) reported it as a vector in his description of the species after receiving the specimens and information from D. J. W. Rose. In my correspondence with Dr. Rose, he stated that transmission of the virus was obtained from diseased plants to healthy maize and wheat. No details of the virus transmission experiments were given.
This species is considered of some importance in the natural spread of this virus in Rhodesia.
Small, fragile species. Length of male 1.80—2.00 mm., female 1.90—2.40 mm.
General color light tan. Crown light tan with two distinct round black spots on anterior margin near mesal margin of eye; pronotum light reddish tan; elytra light reddish tan, translucent.
Pygofer in lateral aspect about as long as wide, caudodorsal margin with long spine projecting posteroventrad, apex of spine asymmetrically bifurcate; aedeagus in lateral aspect simple, tube-like, slightly curved, somewhat broader apically than medially, ventral surface of shaft with pair of short spines arising basally, apex of shaft bifid; gonopore terminal; style in dorsal aspect with apex foot shaped; female seventh sternum in ventral aspect with short median projection on caudal margin (fig. 62).
This species, closely related to zeae, can be separated by the short pygofer process with a dorsal spine.
