Discussion
Which of the following is the main host plant of Tasar silkworm ?
Answer: A
The main host plant is Terminalia arjuna.
Tropical tasar silk is produced by Antheraea mylitta, which feeds on the leaves of arjun (Terminalia arjuna) and asan (Terminalia tomentosa) as its primary food plants, mainly in the forests of Jharkhand, Chhattisgarh and Odisha. Sal is a secondary host.
Phalaris minor is not a silkworm host at all; it is the major grassy weed of wheat. Castor (Ricinus communis, printed here as 'Ricinus recini') is the food plant of the eri silkworm, Samia ricini, not of the tasar silkworm, so 'All of these' is also wrong.
