Tahira Yasmin, Ehsan- Ul-Haq, Saif Khalid and Samman A.Malik

Abstract:
liology of viviparous black banana aphid, PontaIonia nigronervosa Coq., vector of Banana Bunchy Top Virus (BBTV) was studied on banana under growth chamber at a photoperiod of 16:8 hours (light:dark), 55±5 percent humidity and at 20±8°C. From the time of its birth as a nymph, P. nigronervosa took a period of 10 to 14 days with an average of 10.6 days to develop to the final nymphal moult. Fecundity was 1-4 nymphs per day. Over 10 days it ranged from 9 to 26 nymphs/aphid, the average being 13.2. The average body length, width and length of hind tibia of adult aphid were 0.507 mm, 0.282 mm and 358.18 μm, respectively. Life span of P. nigronervosa ranged from 19 to 26 days with an average of 20.3 days.
