Abstract: The present investigation on biology and morphological description 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 first, second, third, fourth and fifth in stars were completed in 1.87 - 4.00, 1.79 - 5.16, 2.13 - 3.00, 1.98 - 4.00 and 2.95 - 4.66 days, respectively. The adult female and male insect can live upto 35.22 - 48.00 days and 40.00 - 47.20 days with food and 1.50-1.80 days and 1.30-1.58 days without food, respectively. The egg, first, second, third, fourth and fifth instars length was with a mean of 0.48 - 0.52, 0.49 - 0.62, 0.72 - 0.82, 0.99 - 1.05, 1.22 - 1.58, 1.88 - 2.11 and 1.88 - 2.11 mm, respectively. The body length of adult female and male insect was 2.27 - 2.67, 2.10 - 2.80 mm, respectively; whereas width of adult female and male insect was1.00 - 1.18, 0.89 - 1.15 mm, respectively.
