Description The biology and morphometrics of pulse beetle, Callosobruchus chinensis
were studied on chickpea cultivar ICCV 2 under laboratory conditions at ICRISAT, Patancheru, Telangana, India
during 2018-19 and 2019-2020. The experiments were carried out in the
BOD incubator at temperature of 28 ± 2ºC and relative humidity of 65 to 70%. The life cyc
le of C. chinensis
included four stages
egg, grub, pupae and adult. The data revealed that eggs
incubation period
in 4-5 days, the grub stage consisted of four instars and its development ranged from 20
-25 days, pupation lasted for 6-
7 days, whereas, female adult longevity ranged from 9
-12 days. The morphometric
measurements revealed that the average length and breadth of eggs were
0.62 ± 0.03mm and 0.34
± 0.02 mm respectively. The length and breadth (mm) of four grub instars G1, G2, G3 and G4
were 0.58 ±
0.02 and 0.30 ± 0.01, 1.53 ± 0.06 and 0.92 ± 0.04, 2.71 ± 0.10 and 1.47 ± 0.06, 3.59 ±
0.14 and 1.96 ± 0.08 respectively. The average length and breadth of pupa were 3.72 ± 0.12 mm,
2.15 ± 0.09 mm. Whereas, the length and breadth (mm) of
adult male and female bruchids were
3.87 ± 0.08, 2.07 ± 0.05 and 4.23 ± 0.14
, 2.31 ± 0.07
respectively. The total life cycle of
C.chinensis
ranged from 33
-42 days
