It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s.

    Bionomics and behaviour of tur pod bug (Clavigralla gibbosa Spinola) on pigeonpea
    (CCSHAU, 2014) Chitralekha; Roshan Lal
    The present study was conducted on four pigeonpea cultivars viz., Paras, Manak, H03-41and UPAS 120 in laboratory of Department of Entomology and screen house at College of Agriculture, CCS Haryana Agricultural University, Hisar. Freshly laid eggs of C. gibbosa were creamy white in colour, after few hours colour changed to brown. Incubation period ranged from 3.3 to 5.9 days with an average of 4.6 ±1.17. Nymphs passed through five instars to become adult. Total nymphal duration ranged from 14.1 to 15.8 days with an average of 14.9±0.69 days. The adults generally started mating in 2 to 14 days with an average of 6.5 days after emergence. The pre-oviposition period ranged from 2 to 11 with an average of 7.0±2.8 days. The oviposition period ranged from 2 to 29 with an average of 19.5±8.18days. The post-oviposition period ranged from 1 to 32 with an average of 17.6±8.8 days. Generally eggs were laid by female in groups. The pods were the most preferred plant part for oviposition. Mostly female laid fertilized eggs. All the stages of C. gibbosa prefer pods for feeding, followed by leaves, flowers and less preferred part was tender shoots. Maximum fecundity and egg hatchability and minimum incubation period, total life cycle of test insect was recorded on Paras. Total nymphal duration, pre-oviposition period and post-oviposition period was minimum in Manak. Oviposition period was maximum in UPAS 120. Total adult life of both sexes was minimum on H03- 41. Paras was the highly preferred cultivar for growth and development. Followed by Manak and UPAS 120 and less preferred cultivar was H03-41.
