Vector capabilities of three aphid species for papaya ringspot virus

Abstract
Three aphid species, namely, Hysteroneura setariae (Thomas), Lipaphis erysinus Hotenvack and Toxoptera citricidus (Kirkaldy), were studied for their potential as vectors of papaya ringspot virus (PRSV) under greenhouse condition. Results obtained confirmed the vector capability of the three species for PRSV. The nymphs of H. setariae and T. citricidus were more effective vectors than adults. In L. erysinus, both stages performed equally. The susceptibility of papaya test plants at different ages was also confirmed. H. setariae proved to be the most efficient among the three, having 23% and L. erisinus at 17%. One month old test plants appeared to be the best for transmission studies. It was also observed that the combined transmission setting of one minute acquisition access period (AAP), one insect vector per test plant-one minute inoculation access period (IAP) expressed as 1 min AAP-1 insect-1 minute IAP, was more effective compared to 24 hours AAP-5 insects-24 hours IAP, in all the transmission tests.
