Studies on the antibiosis mechanism of resistance in different rice accessions against yellow stem borer, Scirpophaga incertulas (Walker)

摘要

The effect of antibiosis on survival and growth of yellow stem borer, Scirpophaga incertulas feeding on different rice accession was studied to identify the rice donors. Among the 16 accessions, developmental characteristics viz., minimum per cent larvalentry, per cent larval survival, larval weight, per cent pupal survival, pupal weight, per cent adult emergence, adult weights and maximum larval and pupal period were observed in TKM 6, IR 20, IET 23715 and IET 23710 and vice versa in TN1, IET 23673 and IET 23681.
