Host preference studies on Callosobruchus chinensis (Linnaeus) in different pulses

Goutam B Hosamani, SB Jagginavar and SS Karabhantanal

The host preference studies on Callosobruchus chinensis in different pulses were made under laboratory conditions. Cowpea (C-152) and greengram (S-4) were most preferred hosts. Blackgram was significantly less preferred for oviposition in F1 generation followed by redgram. In F2 generation Blackgram was significantly less preferred for oviposition followed by redgram. The developmental period (34-36 days in F1 and F2 generation) in redgram, adult (76% to 79% in both generations) and grain weight loss (1.50 to 1.70 percent) was also less followed by Blackgram. Initial germination percentage was not much variation in seed germination among the different pulse varieties redgram (TS-3R) variety (83.67) which was on par with greengram (S-4) (83.33) and least germination was in cowpea (80.00%). Moisture per cent significantly high in red gram (10.00) and least variety mothbean (Vijayapura local) (9.3). Final germination (%) on different pulses after two months were significantly highest observed in blackgram (64.33) followed by redgram and least germination percentage was observed in cowpea C-152 (52.67).
