Demographic parameters of cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae) on five cotton cultivars
Insect Science 13 (3), 205-210
Abstract: Life table parameters of the cotton aphid, Aphis gossypii Glover, were estimated on five cotton cultivars ('Sealand', 'Siokra', 'Varamin', 'Bakhtegan' and 'Sahel'). Demographic parameters of the cotton aphid were assessed at 27.5 ± 1°C, 65%± 10% RH and a photoperiod of 14: 10 (L: D)h. The shortest developmental time for the nymphal stages was 5.5 days on 'Siokra' and the longest was 6.1 days on 'Sealand'. The highest offspring per female was 29.6 on 'Sahel' and the lowest was 15.3 on 'Sealand'. The r_m values varied from 0.272 on 'Sealand' to 0.382 (day^-1) on 'Varamin'. Jackknife estimates of the A. gossypii parameters on these cultivars indicated the greatest developmental rate and fecundity on 'Varamin' and the poorest on 'Sealand' cultivar.
