The effects of 8 varieties each of mungbean, blackgram, pea, cowpea,
lentil, chickpea, and pigeonpea on the feeding and development of
Callosobruchus maculatus (F.) and C. chinensis (L.) were studied by using
whole, decorticated, and autoclaved grains under laboratory conditions in
India. C. chinensis preferred cowpea, followed by lentil, pigeonpea, mungbean,
chickpea, pea, blachgram and C. maculatus preferred mungbean, followed by
cowpea, pigeonpea, chickpea, blackgram, pea, and lentil. No significant
difference between bruchid growth and development on the different varieties of
the same food plant was observed, although there were significant differences
among the different plant species. Mixing lentil flour with mungbean flour had
a aeleterious effect on the growth and development of C. maculatus, and
similarly mixing blackgram flour with mungbean flour affected C. chinensis.
Extracts of lentil flour mixed with the preferred mungbean flour did not
produce any adverse effect on the growth and development of two beetlev.
Extracts of blackgram flour had no effect on C. maculatus and only hydrochloric
acid extract of blackgram affected C. chinensis. [THH]

The eggs and larvae of Callosobruchus subirotatus irradiated with gamma
rays of 2.5 to 20 kR. No eggs hatched after irradiation at D kR. All larvae
were dead in 7 days after irradiation at 5 kR. A doie of 20 kR reduced
emergence of adults by 99.17%. The sterilization of adult males and females can
be outained with a dose of 5 kR. [THH]

Qualitative and quantitative feeding by developing stages of Callosobruchus
maculatus (Fab.) and Callosobruchus chlnensis (Linn.) were estimated on
mungbean seed at 30, 50, 70, and 90% relative humidity at a conbtant
temperature of 2' [plus or minus] 1.5 C. The feeding as loss in weight of seed
progressed in three stages corresponding with early, mid and late stages of
development. The relative humidity significantly affected the feeding besides
sex and type of species. The ratio of food eaten by C. maculatus to C.
chinensis was 1.45:1.00 and the corresponding ratio of emerged adult weight was
1.60:1.00. The weight loss in seed ranged from 55.6 to 60.0% for C. maculatus
and 30.2 to 55.7 for C. chinensis. The loss in protein was from 44.5 to 66.3%
ty C. maculatus and 17.C to 53.5% by C. chinensis. [AS]
