Smoking â Tobacco use is one of the major risk factors for cancer of the pancreas. It is believed that those who smoke are twice as likely to get the disease. Obesity â As we know, obesity is a strong risk factor for many diseases, not just cancer.
The silkworm is the larva or caterpillar of the domesticated silk moth, Bombyx mori (Latin: silkworm of the mulberry tree). It is an economically important insect, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other mulberry species and even osage orange. Domestic silk moths are closely dependent on humans for reproduction, as a result of millennia of selective breeding.
Again, I've provided a link below. Many sites give detailed advice on how to raise silkworms, I've provided some links below, and some give hints about securing a supply of Mulberry leaves. Other species of silk moth have silkworms that eat different plants, such as oaks, castor-oil plants and Polyanthus. Some silkworms are polyphagous, and will eat a variety of plants. These are extremely uncommon compared to Bombyx mori, and its highly unlikely that you'll come across these silkworms.
