Abstract: A biological and morphometrical study on spotted pod borer, Maruca vitrata (Geyer) was studied on pigeonpea early variety BDN-711 during Kharif-2017 at Entomological Research Laboratory VNMKV, Parbhani. The egg period counted 2.63 ± 0.42 days. There were five larval instars with mean larval duration of 9.61 ± 1.80 days. The measurements (length x breadth) of first, second, third, fourth and fifth instar larvae were 1.32 ± 0.01 x 0.18 ± 0.006, 2.50 ± 0.04 x 0.40 ± 0.01, 5.60 ± 0.07 x 0.90 ± 0.02, 11.12 ± 0.11 x 1.80 ± 0.10 and 15.95 ± 0.13 x 2.82 ± 0.09 mm, respectively. However length x breadth of pupa, male and female were 13.01 ± 0.12 x 2.75 ± 0.05, 12.62 ± 0.20 x 0.90 ± 0.04 and 13.02 ± 0.20 x 0.93 ± 0.05 mm respectively. Mean fecundity was 144.5 ± 100.2 eggs. The pre-pupal and pupal period lasted for 2.01 ± 0.28 and 7.64 ± 1.92 days respectively. Longevity of male and female moths was 10.25 ± 3.05 and 12.67 ± 3.55 days, respectively. Whereas mean total developmental period 22.88 ± 1.25 days.
