|Crops Affected by Empoasca devastans Distant|
Thomas and Krishnaswami (784) first reported in 1939 this species as a vector of little leaf of brinjal (eggplant). However, only one of nine plants tested became diseased. There are no records confirming transmission, and it is unlikely that the Species will become important as a vector owing to its association with cotton.
Small, fragile species. Length of male 4.50—5.00 mm., female 5.00 mm.
General colour yellow. Crown yellow with two black spots on anterior margin; pronotum orange yellow; elytra light yellow with two black spots distad of middle.
Pygofer in lateral aspect about as long as wide, ventral margin with distinct long spine extending posterodorsad beyond dorsal margin of pygofer; aedeagus in lateral aspect with long basal process; aedeagal shaft curved, short, attenuated apically; gonopore apical; style in dorsal aspect simple, lateral margin of apices serrate; female seventh sternum in ventral aspect with caudal margin convergent apically.
This species is similar to
in genital characteristics and can be distinguished by the male pygofer with a long, ventral, spinelike process.
