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.
Most moths and nearly all butterfly caterpillars eat the leaves and flowers of plants. Some moth caterpillars eat fruit, or seeds, and a few eat animal foods like beeswax or fur. A very few species of caterpillars are carnivores, eating aphids or other soft-bodied insects. Adults mostly drink nectar or sap.
