Abstract
Samia ricini,
a multivoltine species, can be reared on various food plants due to its
polyphagous nature. The selection of suitable host plants is crucial for
effective ericulture, as they significantly influence rearing parameters such
as survival rates, larval duration, cocoon quality, and moth emergence. This
study reports the use of Oroxylum indicum and Ficus racemosa as
alternate host plants for rearing S. ricini, in addition to conventional
host plants Ricinus communis and Heteropanax fragrans. These
plants were found to provide sufficient leaves during summer (O. indicum),
rainy (F. racemosa, O. indicum), and winter (F. racemosa)
seasons. A satisfactory correlation was observed between growth parameters and
the leaves of these two plants, with an overall effective rearing rate of
89.55±0.76% and 86±0.63% for F. racemosa and O. indicum,
respectively. However, the knowledge of using these plants is currently
limited, highlighting the need for broader dissemination to enhance
productivity and silk yield.
