Online published on 5 February, 2019. Abstract This study evaluates the biology of the pigeon pea pod bug Clavigralla gibbosa Spinola on two genotypes of pigeon pea viz., GT-101 and IPS-51. The results of the study done at the laboratory of Centre of Excellence for Research on Pulses, S. D. Agricultural University, Sardarkrushinagar during 2012-13 revealed no significant differences in the morphometrics and duration of life stages. The total life cycle occupied slightly lesser time with the genotype GT-101- in case of male it was 61.35 ± 9.87 days and in female for 69.30 ± 11.21 days. Fecundity and hatching % were more when reared on the genotype GT-101. Likewise the sex ratio (male: female) was observed to be 1:1.27 and 1: 1.17 in the genotypes GT-101 and IPS-51, respectively.
