abstract
The study was to investigate the evaluation of insecticides on oviposition of pulse beetle Callosobruchus chinensis (L.) (Coleoptera: Bruchidae) in greengram varities and cowpea varities at Agriculture college Vijajapura, UAS Dharwad during Kharif 2014-15. Among the greengram genotypes, the least number of oviposition was recorded in S-4 (22.94).Significantly the highest number of eggs was recorded in shinning moong variety (27.41). Among the insecticides NSKE @ 5 percent (18.51) and malathion 50EC (23.07) are promising in the control of field carryover of pulse beetle in greengram whereas in cowpea genotypes minimum numbers of eggs were recorded in C-152 cowpea genotypes (28.60) Significantly the highest number of eggs were registered in DCS 47-1 (29.54) None of the insecticides were promising in control of Ovipostion of pulse beetle but field carry over can be minimized to certain extent by malathion 50EC and botanicals such as NSKE 5 % and castor oil in both green gram and cowpea crops. This indicates that the infestation is from field to laboratory.
