| Sumario: | Development periods of immarure stages, fecundity and longevity of females of two biotypes ("B" and "non B") of Bemisia tabaci (Gennadius) on three varieties of Capsicum annuum L. at constant temperature (25 ± 1ºC were studíed. The mean (± SE) developmenr time (egg-adult, in days) of the "B" biotype on Morrón (16±0.37) was significantly (p < 0.05) sborter than was on Yolo-wonder (22.83 ± 0.48) and Piquillo (19.02 ± 0.52). In contrast, the "non B" biotype developed faster on Yolo-wonder (16.91 ± 0.42) than on Morrón (19.70 ± 0.37) and Piquillo 18.89 ± 0.38). The average oviposition(eggs per female) of "B" biotype was significantly greater on Piquillo (214.00 ± 6.77) than was on Morrón {l94.13 ± 5.71) and Yolo-wonder (66.53 ± 4.56). In contrast, "non B" females laid more eggs on Morrón (217.20 ± 7.71) and Yolo-wonder 226.20 ± 6.14) than on Piquillo (134.40 ± 3.72). With respect to adult longevity (in days), "B" females lived longer on Piquillo plants (24.00 ± 0.62) than on Morrón (l8.27 ±0.43) and Yolowonder (15.33 ± 0.65). In contrast, the average longevity of "non B" females was shoter on Piquillo (18.73±0.64) than was on Morrón (24.47 ±0.74) and Yolo-wonder (24.87 ± 0.70). From these results we conclude that there was evidence of different reproductive capacity between "B" and "non B" biotypes of B. tabaci on some C. annuum varieties: Whereas Piquillo was more suitable host for "B" biotype Morrón and Yolo-wonder were better hosts for "non B". |
