Summary Settling, probing and oviposition behaviour ofCicadulina mbila, the main vector of maize streak virus (MSV) disease were studied on four maize genotypes, 100MSR, HASR, Reunion and H512. Of the four, only H512 was completely susceptible to MSV while the other three genotypes were all known to have some resistance to MSV. Generally,C. mbila settled in higher numbers on the MSV susceptible genotype compared to the three virus resistant ones. However, the number of probing marks left on H512 and 100MSR were similar while more marks were made on Reunion and HASR in increasing order. The oviposition patterns were similar to those observed for probing behaviour. The results suggest the existence of potentially useful resistance mechanisms against the vector. The possible implications of these results are discussed.
