oa Journal of the Entomological Society of Southern Africa - The antennae, host plant chemoreception and probing activity of the citrus psylla, Trioza erytreae (Del Guercio) (Homoptera: Psyllidae)



The morphology of the antennae of the citrus psylla Trioza erytreae, as revealed by scanning electron microscopy, is descriptionbed with reference to the six prominent sensoria (rhinaria) on the flagellum. The probing and walking activities of individual psyllids were analysed for intact and antennaless insects, on host plant leaves (rough lemon) and non-host leaves (mulberry and nasturtium).
