| dc.description.abstract | Comparative biology of L. erysimi was studied on four different hosts viz., cabbage, cauliflower, mustard and radish under laboratory conditions. The mean total nymphal period on different hosts ranged from 5 to 8 days being minimum on radish 6.08 ± 1.10 days with a range of 5 to 7 days while maximum on cabbage with an average of 7.52 ± 0.57 days and range of 6 to 8 days. The mean duration of longevity ranged from 5 to 11 days in different hosts. Adult longevity was maximum on cabbage 8.56 ± 1.13 days with a range of 6 to 11 days and minimum on radish 7.20 ± 1.91 days with a range of 5 to 10 days. The highest pre-reproduction period was found in cabbage (1.20 ± 0.40) with a range of 1-2 days and the lowest pre-reproduction period was found in radish (0.68 ± 0.47) with a range of 0-1 days. The highest reproduction period was recorded in cabbage (6.40 ± 0.66) days with a range of 5-8 days and the lowest in radish (5.60 ± 0.80) days with a range of 5-7 days. The highest post-reproduction period was reported in cabbage (0.96 ± 0.66) days with range of 0-2 days and the lowest in radish (0.76 ± 0.58) days with a range of 0-2 days. The data on fecundity revealed that the mean number of nymphs laid on different hosts ranged from 12 to 39 nymphs per female being maximum on cabbage (29.48 ± 4.30) followed by cauliflower (28.80 ± 3.29) and mustard (26.52 ± 8.10). The minimum number of nymphs (23.96 ± 5.55) was laid on radish. | en_US |
