1. Smell with the nose. When entering the silkworm room, smell the odor in the room. If the room has only the fresh scent of mulberry leaves and no other strange odor, it indicates that the grown silkworms are disease-free. 2. Listen with the ears. After feeding mulberry leaves, if the sound of the silkworms eating mulberry leaves is heard like the rustling of light rain, it indicates that the grown silkworms are healthy. 3. Look with the eyes. Observe the body color of the silkworms. Healthy silkworms generally have a blue-white body color. Silkworms at the peak of feeding have tight, glossy skin and are lively in movement, raising their heads and thoraxes when resting; the dorsal vessel beats rhythmically; the group develops uniformly in size; the feces have a certain shape (except for mature silkworms),

4. Blow with the mouth. After gently blowing air toward the silkworm seat with the mouth, healthy silkworms immediately raise their heads and thoraxes.

5. Touch with the hands. First, place the back of the hand against the silkworm's body. If the silkworm's body feels relatively firm and cool; second, when picking up a silkworm with the hand, if the silkworm resists strongly, it indicates that the silkworm is healthy.
