Study of the coccinellid, coccinella transversalis F. (Coleoptera: coccinellidae), and its role as biological control agent

Coccinellid, Coccinella transveraslis F. (Coleoptera: coccinellidae), was one of the important natural enemy of aphid species. The females of C. transversalis can lay eggs 645.27+-213.37 eggs in their ife. Their egg stage was 2.55+-0.5 days. The 1st, 2nd, 3rd and 4 the were 1.9+-0.31, 1.33+-0.35, 2....

Summary:Coccinellid, Coccinella transveraslis F. (Coleoptera: coccinellidae), was one of the important natural enemy of aphid species. The females of C. transversalis can lay eggs 645.27+-213.37 eggs in their ife. Their egg stage was 2.55+-0.5 days. The 1st, 2nd, 3rd and 4 the were 1.9+-0.31, 1.33+-0.35, 2.17+-0.38 and 2.87+-0.57 days, respectively. The pupal stage was 3.17+-0.38 days. The longevity of adult male and female were 37.4+- 16.95 and 45.53+-18.15 days, respectively. Life table and feeding capacity of C. transversalis on three aphid species, Aphis craccivora Koch (Homoptera: Aphididae), Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae) and Myzus persicae (Sulzer) (Homoptera: Aphididae) were investigated under laboratory condition (28+-2 deg C and 75+-3 percent R.H.). The results were shown as following: the net reproductive rate of increase (R sub(o), the capacity for increase (r sub(c)), the finite rate of increase (lambda), and the cohort generation time (T sub(c)) on A. craccivora were 447.6444, 0.1719, 1.1876 and 35.5013 days, respectively, (R sub(o)), (r sub(c)), (lambda) and (Tsub(c)) on L. crysimi were 130.064. 0.1172, 1.1243 and 41.5686 days, respectively and (Rsub(o), (r sub(c)), (lambda) and (Tsub(c)) on M. persicae were 56.1334, 0.1244, 1.1243 and 32.3689 days, respectively. These results indicated that A. craccivora was most suitable prey in the massrearing of C. transversalis. The predation capacity of larval instars and adult stage were 119.5+-11.27 and 1,251.45+-238.69 aphids, respectively.
