abstract
The present investigation on life-table of Ocimum tingid Cochlochila bullita (Stal.) on camphor tulsi were carried out during 2016-2017 at Dept. of Agri. Entomology, UAS, GKVK, Bengaluru. The incubation period of the eggs of C. bullita varied from 8.95 to 10.12 days, with an average of 9.37±0.57 days, nymphs took 12.86 to 17.81 days to complete five instars with an average of 14.85±1.61 days and total developmental period from 21.81-31.37 days with a mean 24.18±0.74 days. The life fecundity table were studied for C. bullita on camphor tulsi under laboratory conditions at 28.30 to 36.00 ^oC. The net reproductive rate (R_o) was 1182.82 females with generation period (T) was 26.88 days. The innate capacity (rm) and finite rate of increase (λ) for increase in number was calculated to be 0.2632 and 1.32 female/day, respectively with weekly multiplication rate of 6.91 times.
