Abstract

Ollarianus balli (Van D.), a leafhopper vector of disease-associated mycoplasma-like organisms, was found to be rare in Jamaica. Its distribution and frequency were governed primarily by the distribution and density of its specific field host, the wild legume Rhynchosia minima on which it completes its life-cycle. Under suitable temperature conditions, O. balli was easily reared in captivity on R. minima and pigeon pea (Cajanus cajan), although the latter is not a natural host. It oviposited into the hypodermal tissues covering veins of sterns, petioles and the abaxial surfaces of older leaves. Eggs hatched 10–15 days after oviposition and there were five nymphal instars. Instar 1 was distinct from instars 2–5 which, except for size, were similar in appearance. The first adults matured some three weeks after the final moult. There appeared to be little difference in the average life-span of males and females of O. balli.
