Biology of tur pod bug, C. gibbosa was studied under laboratory conditions on pigeonpea variety viz., Manak in vitro at prevailing room temperature 26±1°C and relative humidity 75 per cent from mid October 2013 to January 2014. Eggs were laid in clusters in the batches of 2 to 33 eggs. The incubation period was 5.7 days. There were five nymphal instars with a mean of 1.7, 1.9, 2.4, 3.8 and 5.1 days for 1st, 2nd, 3rd, 4th and 5th nymphal instars respectively and the total nymphal duration recorded was 14.9 days. Total adult life of male was 15.6 and that of a female 23.7 days. Total life cycle was completed in 24.11 days on an average. The results revealed that the pre-oviposition, oviposition and post-oviposition period averaged 7.5, 12.8 and 8.6 days, respectively. The fecundity was 100.6 eggs/female from which 83.56 per cent eggs hatched.
