Abstract
The present study investigated the biochemical factors related to
resistance and susceptibility of Callosobruchus chinensis (L.) and Callosobruchus
maculatus (F.) in response to twenty-five different genotypes of Vigna
mungo (L.) Hepper. Results revealed that, out of twenty-five cultivars of V.
mungo differential resistant to C. maculatus was observed. It
was found that the cultivar IC-436511 was more susceptible because the life
cycle of the bruchid completed only in 31.00±1.00 days, maximum 87.00±1.63 eggs
were laid and 49.67±4.04 adult emerged successfully with the growth index of
1.61. Whereas, cultivars DKV-116 was least susceptible to the attack of C.
maculatus since pest completed its life cycle in 34.33±1.15 days with
91.33±6.65 eggs and adult emerged 33.67±2.52 with growth index of 0.98. From
the present studies, it has been concluded that blackgram cultivars are
completely resistant to the attack of C. chinensis but most susceptible
to C. maculatus.
