Abstract:
Biology and predatory potential of C. transversalis (Fab.) on B. Brassicae (Linn.) were carried out in Biocontrol laboratory during the year 2019-2020 at Department of Entomology, IGKV, Raipur. Coccinella transversalis passed through four instars, 1st, 2nd, 3rd and 4th instars, ranging from 2-4, 3-4, 3-4 and 4-6 days with an average duration of 3.00 ± 0.60, 3.20 ± 0.42, 3.40 ± 0.52 and 5.10 ± 0.57 days respectively. Grub period ranged from 12-18 days with mean of 15.00 ± 1.56 days. The prepupal and pupal period was of 1.30 ± 0.46 and 3.30 ± 0.48 days. Longevity of female ranged from 32-40 days and male ranged from 24-37 days. Results showed that the total consumption of aphids in grub stage of C. transversalis ranged from 75-83 with an average of 78.70 ± 2.79 per day and the total consumption of aphids during adult period was 48 to 50 aphids with an average of 48.60 ± 0.84 aphids/day. Total aphid consumption during the entire life ranged from 128-132 aphids /day with an average of 129.0 ± 1.32 aphids/day.
