Abstract

Oviposition, development and survivorship of Bemisia argentifolii Bellows & Perring, were evaluated on two cultivars of hibiscus (Hibiscus rosa-sinensis L.), ‘Brilliant Red’ and ‘Pink Versicolor’. B. argentifolii deposited significantly more eggs and survivorship of nymphs was significantly greater in choice tests on ‘Pink Versicolor’ than on ‘Brilliant Red’. Overall developmental time of B. argentifolii from egg to adult eclosion was longer on ‘Brilliant Red’ than on ‘Pink Versicolor’. Although not all differences between the two cultivars were statistically significant, ‘Brilliant Red’ could be considered a less favorable host for silverleaf whitefly than ‘Pink Versicolor’. However, based on the intrinsic rate of increase (r = 0.105) and finite rate of increase (l = 1.22) of B. argentifolii, even ‘Pink Versicolor’ was a poor host for B. argentifolii compared to published values for eggplant, tomato, sweet potato, cucumber, garden bean, or collard.
