(1) What are maggots
Maggots are larvae of invertebrate insects, Diptera, and are called headless larvae because their heads and mouthparts are extremely degenerate. For example, maggots, the larvae of flies, are headless larvae.
(2) The role of maggots in the environment
The industrial wastes produced in many food processing enterprises, such as beer lees, expired and spoiled food and other scraps, can be used by house flies and fly maggots, and can effectively reduce the pressure on the environment caused by these industrial wastes, which is superior to the use of other technologies to treat livestock manure and food processing wastes. Therefore, fly maggot farming can clean up the environment by using livestock manure and food industry waste. House flies can quickly convert pig manure, chicken manure, cow manure, human manure, and household garbage into protein. Fly maggots are a high-quality animal protein feed. Fly maggot feed is highly palatable, highly convertible and nutritious. It has been confirmed that using fly maggots to replace part or all of fish meals as feed for livestock, poultry, fish, etc., has achieved better breeding results.
(3) The role of maggots in medicine
Clinical studies by Mexican medical experts have proved that maggots contain bactericidal salts in their excrement after devouring carrion and substances in their bodies that help ulcer wounds heal, such as antibiotics and improving patients' immunity, thus preventing patients from undergoing amputation due to limb ulceration. When the larvae devoured about 10 mm of carrion and were replaced with new larvae, the area of necrotic tissue in the patient's wound was reduced more quickly and the rate of granulation tissue production and wound healing was faster.
1.什么是"蛆虫"？
"蛆虫"是无脊椎昆虫中，双翅目昆虫的幼虫。由于它们的头部和口部非常不发达，在人们的称呼中常被形容为"无头幼虫"。例如，飞蝇蛆就是一种双翅目昆虫的幼虫。
2.蛆虫在环境中的作用
许多食品加工企业都会产生大量工业废物，如啤酒糟、失效食品和其他废弃物等。但这些废物可以被家蝇和飞蝇蛆吃掉消化。这种方法不仅能有效降低这些工业废物对环境造成的负荷，而且比其他处理畜禽粪便和食品加工剩余物的技术更加优越。因此，通过飞蝇蛆养殖能够利用畜禽粪便和食品业废弃物来清理环境，这是比较有效的办法之一。家蝇能够迅速将猪粪、鸡粪、牛粪、人类粪便以及家庭垃圾等转化为蛋白质。而飞蝇蛆则是一种优质的动物蛋白饲料。飞蝇蛆饲料味道美味、易于消化，为动物提供充足的营养素。之前实验证明，将飞蝇蛆作为家畜、家禽、鱼类等的饲料，可获得更好的养殖效果。
3.蛆虫在医学中的作用
墨西哥的医学专家通过临床研究发现，蛆虫可以吃掉腐烂的肉，排出一些含有杀菌盐和有助于口腔溃疡伤口愈合的物质，如抗生素，同时促进患者免疫系统的提高，从而帮助患者避免肢体溃烂而导致截肢。当幼虫吃掉了溃疡周围约10毫米的坏死组织后，将其替换新的幼虫，可以促进肉芽组织的生成，并加速伤口的愈合。
