<br/><br/> Silkworm is a typical monophagous insect and mulberry (Morus spp.) leaf is its sole feed. The current investigation aims to <br/>compare biochemical and economic characteristics of two hybrids of silkworms (B. mori. L.). Two hybrids of Bombyx mori, (L.) <br/>(H1xKKxG2xV2) and (Giza B) silkworm larvae were fed on mulberry leaves Morus indica var kanava-2 planted in the experimental <br/>farm during the spring season for biochemical and economic studies. Mulberry leaves were offered four times per day. <br/>The imported hybrid (H1xKKxG2xV2) showed higher and consistent growth rates than the native hybrid (Giza B) for all the <br/>developmental stages. It can be concluded that the selection of strong hybrids from silkworm and feeding on a good variety <br/>of Indian cultivar Morus alba var. kanava-2 imported from Indian improves the growth value of biological and economic parameters.<br/>Keywords: Bombyx Mori L.; Biochemical character; Silkworm.<br/>
