- Egg Stage: The life cycle begins with the tiny, oval-shaped eggs laid by the female moth. These eggs are usually laid on mulberry leaves and are initially white, gradually darkening before hatching. Incubation time is crucial and depends on temperature and humidity.
- Larval Stage (Caterpillar): Once hatched, the larvae, commonly known as silkworms or caterpillars, commence voraciously feeding on mulberry leaves. They undergo several molts (ecdysis) as they grow, shedding their exoskeletons to accommodate their increasing size. This stage is where they produce silk. It’s critical to maintain a consistent supply of fresh, high-quality mulberry leaves.
- Pupal Stage (Cocoon): After several weeks, the fully grown larva begins to spin a cocoon, a protective casing of silk fibers. This is where silk production happens and is one of the critical stages in determining the quality and yield of silk. The process of cocoon formation can take several days.
- Adult Stage (Moth): Once the pupation is complete, the adult moth emerges from the cocoon. The primary role of the adult moth is reproduction. The female moth lays eggs, beginning the cycle anew. Typically, after mating and egg-laying, the adult moths die. Thus, the cycle goes on.
Understanding each stage is critical for effective silkworm management. Each stage has specific environmental and nutritional requirements that must be carefully monitored and controlled to ensure optimum productivity and silk quality.
