BIOLOGY OF PLATYNASPIS SAUNDERSI (COLEOPTERA: COCCINELLIDAE).

Biology of Platynaspis saundersi (Crotch) was studied under laboratory conditions at the Department of Entomology, Dr YSP University of Horticulture and Forestry, Himachal Pradesh, India. The mean preoviposition period was 7.00± 0.21 days, while the oviposition period was 43.50± 0.35 days. The female lays 130.30± 5.96 eggs and the hatching was 86.32± 3.12%, with incubation period being 5.0± 0.47 days and the larval period was for 12.40± 0.35 days. The observed prepupal and pupal periods were 1.50± 0.48 and 7.50± 0.21 day, with longevity of male and female being 70.00± 2.00 and 79.00± 0.89 days, respectively. [ABSTRACT FROM AUTHOR]
