Abstract :
Scirpophaga incertulas W commonly known as
Yellow Stem Borer (YSB), is a major insect pest of rice
and causes a devastating effect on rice crop productivity.
YSB specifically attacks at the young vegetative stage
which leads to “dead heart” while the damage at
reproductive stage results in “White Ear Head”. Despite
of its huge impact on agriculture sector across the globe
no much molecular work was initiated due to difficulty in
rearing. Hence in the given study, we aimed at developing
a cost effective artificial YSB rearing system on natural
diet. We designed our experimental model by using
different naturally derived food sources (starch, sucrose
and honey) as well as synthetic components (combination
amylose and amylopectin). The findings of this study
demonstrated that the YSB was successfully reared on
natural starch, sucrose and synthetic starch under
standard growth conditions. Establishment of such
rearing method would definitely provide an instant source
of different stages of YSB. These readily available stages
of YSB can be deployed in studies involving optimization
of bioassays, understanding lacunae of developmental
studies and also in evaluating the effect of extrinsic
factors. The outcome of this study will definitely leave a
huge impact on developing an efficient pest management
strategy against YSB.
