Abstract
Agriculture plays an
important role in the economic position of developing countries. The chemical
control is generally practiced by farmers for higher crop yield, but this
injudicious application has created many health hazards. Under such
circumstances the use of bio pesticides in pest management is considered as
environment friendly. Bracon hebetor is a cosmopolitan polyphagous
ectolarval parasitoid of many lepidopteran pest larvae of field crop as well as
stored products. To enhance the biological control program it is necessary to
study parasitizing ability of B. hebetor on various host species. Hence
the present study aimed to determine the efficacy of B. hebetor
parasitoid on E. zincknella. We compared parasitization of B. hebetor
on four different lepidopteran pest. A comparative study of parasitization of B.
hebetor to E. zincknella. M. vitrata, E. vittella and C.
cephalonica was undertaken during the period of December to January 2024 by
providing them a alternate hosts under laboratory conditions the present study
investigated that when all hosts were offered to B. hebetor the highest
parasitization occurred on C. cephalonica followed by M. vitrata,
E. zincknella and E. vittella. When two host were offered B. hebetor
preferred C. cephalonica over M. vitrata, M. vitrata over Etiella
zincknella and Etiella zincknella over Earias vittella when
individual host where offered B. hebetor depositing more eggs forming
more larvae, pupae and emerging more adults on C. cephalonica followed
by. M.vitrata, E. zinckenella and E. vittella. It was evident
that B. hebetor paralysed and parasitized Etiella zincknella, hence B.
hebetor proved effective parasitoid of E. zincknella.
