Abstract

The experiment on biology and morphomatrics of Hadda beetle, Henosepilachna vigintioctopunctata (Fab.) was studied on Indian ginseng, Withania somnifera (L.) Dunal under laboratory, Department of Entomology, Sri Karan Narendra Agriculture University, Jobner, Rajasthan.  Result showed that the fecundity ranged from 210 to 327 and incubation period was 7 to 10 days. It has four larval instars, with total larval and pupal period being 12-18 and 4-8 days, respectively.  The average longevity of male and female was 50.3 and 64.8 days, respectively. The average body length of male was 6.21 ± 0.17 mm and breadth was 4.62 ± 0.28 mm, whereas, in female length was 7.15 ± 0.28 mm and breadth was 5.19 ± 0.27 mm.
