Som (Persea bombycina) is an important primary food plant for Muga silkworm, Antheraea assamensis Helfer. which is dented by diverse insect pest complex belong to different insect order and family under class of Insecta and phylum of Arthropoda viz. Stem borer, Gall fly, Hairy caterpillar, White ant, Beetle, and some Sucking pest of Aphids and Thrips. Muga silkworm Antheraea assamensis Helfer is a widespread to Assam in North Eastern India and is semi cultivated, multivoltine and has enormously part role for growth of sericulture wealth since it is being in golden yellow colour. A vigorous and healthy food plant, good leaf with enough nutrients, Agro climatic condition with suitable environment weather seasons are very much indispensable factors for the growth, development, and improvement of the silkworm and too for the fabrication of high-quality of raw silk. Since this silkworm is rearing outdoor in nature and entirely depend on environment climatic condition, its yield is inhibited by many biotic and abiotic vagaries. One of which stem borer that cause stern damage to the host plant. This stem borer is having different species out of which four species are very perilous which includes Bactocera titana Thoms, Bactocera rufomaculata, Xylotrichus sp., Carpenter moth (Zeuzera multistrigata Moore). This piece of writing appraisal strictly focus on stem borer invasion on som plant (Persea bombycina) besides covers its biology and management measures of above stem borer
