Muga silkworms, Antheraea assamensis (Helfer) (Lepidoptera: Saturniidae) is a semi-domesticated sericigenous insect that produces the costliest golden colored exquisite silk. The silkworm is endemic to Assam and the adjoining areas of northeastern India. This multivoltine silkworm feeds on a variety of perennial food plants. However, less is known about the food plants of the silkworm other than the primary ones, namely Persea bombycina Kost. and Litsea monopetala (Roxb.) Pers. (both Lauraceae) in terms of rearing performances, diversity, nutritional aspects, and silkworm-food plant relationships. Here, we review the utilization and present status of the food plants of Muga silkworm based on published information and field observations. Although 37 species belonging to eight familiesnamely Magnoliaceae, Lauraceae, Celastraceae, Verbenaceae, Apocynaceae, Symplocaceae, Rutaceae, and Rhamnaceaewere reported previously, only P. bombycina and L. monopetala have been exploited commercially and are being utilized in silkworm farming. Some other food plants documented previously are six Cinnamomum spp., five Litsea spp., three Symplocos spp., three Zanthoxylum spp., three Persea spp., three Actinodaphne spp., and two Celastrus spp. Systematic documentation, evaluation, and conservation of these food plants of Muga silkworm is urgently needed to preserve their gene pool in wild habitats. Silkworm farming in forest vicinity and tea silkworm-based farming (as shade tree) may be experimentally tried which will aid the conservation of biodiversity with economic benefit.
