Beneficial Insects And Spiders

People depend on insects to pollinate their crops, ensuring that they have plenty of food, fiber, and other useful products. Honeybees are not only valued for their pollination services but also for their honey and wax. Silk from the cocoons of the silk moth, Bombyx mori, has been harvested for centuries. Each caterpillar must eat 125 pounds (56.7 kilograms) of mulberry leaves before it can spin a cocoon. About seventeen hundred cocoons are required to make one dress. China and Japan are the world's largest producers of silk.

Beekeeping and silkworm culture were the first forms of insect farming, but today many other insects are raised and sold for use as research animals, fish bait, and pet food. Others are used to combat weeds and insect pests. Butterflies and other tropical insects are raised and shipped alive to insect zoos and butterfly houses around the world. Money earned by butterfly farmers in Central and South America, Malaysia, and Papua New Guinea is used to support families, to maintain the farm, and to preserve or improve butterfly habitats.

Grasshoppers, termites, beetles, caterpillars, and crustaceans are important sources of food for humans and are even considered delicacies in many parts of the world. They are an excellent source of fat and protein. Western European culture has largely ignored insects as food but considers lobster, crab, and shrimp as delicacies.

Every species of arthropod is a flying, walking, or swimming pharmacy filled with potentially useful medicines and other chemical compounds. For example, venoms from insect stings are used to treat patients with rheumatism (RU-me-TIH-zem), a disease that affects the joints. The venom helps to increase blood flow to the diseased joints and stops the pain.

Arthropods also provide an early warning system for detecting changes in the environment caused by habitat destruction, pollution, and other environmental disturbances. Aquatic insects and arthropods living in the ocean are especially sensitive to even the smallest changes in water temperature and chemistry. The presence or absence of a particular species may demonstrate that a particular habitat is polluted as a result of illegal dumping, pesticides from nearby agricultural fields, or chemical waste from mining operations.
