Tasar silkworm feeds on leaves of________a. Mulberryb. Castorc. Berd. Rubber

Answer: c. Ber
The Tasar silkworm (Antheraea mylitta), which produces Tasar silk, primarily feeds on the leaves of Ber (Ziziphus mauritiana) and other host plants such as Arjun (Terminalia arjuna) and Asan (Terminalia tomentosa). Tasar silk is a type of wild silk, and the silkworms are reared in natural forests.
1. Host Plant - Ber:
o Ber leaves are rich in nutrients, which are essential for the growth and cocoon production of Tasar silkworms.
o The Tasar silkworms feed on these leaves during their larval stages.
2. Why not other options?:
o a. Mulberry: This is the primary host plant for the Mulberry silkworm (Bombyx mori), not the Tasar silkworm.
o b. Castor: Castor leaves are the primary food for the Eri silkworm (Samia ricini).
o d. Rubber: Rubber plants are not used as a host plant for any type of silkworm.
Thus, the correct answer is c. Ber, as it is the primary food plant for the Tasar silkworm.
