Abstract
Studies on culturing and identification of Callosobruchus maculatus
(Bruchidae: Coleoptera) in Vigna radiata and Vigna mungo,
the present lab work was carried out at the Department of Zoology of BSNV PG
College, Lucknow during 2024. Bean beetles is an important stored grain pest
distributed in Asia and Africa from tropical and subtropical world. C. maculatus
also feed on other legumes but the cowpea and chickpea are the favourite hosts
for cowpea weevil. Grains were collected from various shops of local market of
Lucknow and also Indian Institute of Pulse Research Kanpur. Grains of Vigna
radiata and Vigna mungo were kept in jars (5 lit.
capacity) and covered with muslin cloth fastened with rubber bands with 28±2oC and 70±5 % RH with a photoperiod of
12h L:12h D in laboratory. The adult pulse beetles were ready to mate,
oviposit, and grow their progeny, and observe adult emergence in daily basis,
(0-1 day old) adults from the F1 progeny were used in the experiments. In this
experiment we find out the result of oviposition, number of adults emerged,
mean developmental period of C. maculatus, C. chinensis and C. analis.
The number of eggs laid, number of adults emergence was seen highest in C.
maculatus and C. chinensis while lowest in C. analis in both Vigna
mungo and Vigna radiata. The mean developmental period was
lowest in C. maculatus and C. chinensis while in C.
analis mean developmental period for both Vigna species are highest.
