Infestations can be classified as either external or internal with regards to the parasites' location in relation to the host. External or ectoparasitic infestation is a condition in which organisms live primarily on the surface of the host (though porocephaliasis can penetrate viscerally) and includes those involving mites, ticks, head lice and bed bugs.
The first report of the use of an insect species to control an insect pest comes from "Nanfang Caomu Zhuang" (南方草木狀 Plants of the Southern Regions) (c. 304 AD), attributed to Western Jin dynasty botanist Ji Han (嵇含, 263–307), in which it is mentioned that "Jiaozhi people sell ants and their nests attached to twigs looking like ...
Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.

Insects are responsible for two major forms of damage to crops. First, there is the direct injury they cause to the plants as they feed on the tissues; a reduction in leaf surface available for photosynthesis, distortion of growing shoots, a diminution of the plant's growth and vigour, and the wilting of shoots and branches caused by the ...
Myiasis (/ m aɪ. ˈ aɪ. ə. s ə s / my-EYE-ə-səss [1]), also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae that grow inside the host while feeding on its tissue.
A bacteriome is a specialized organ, found mainly in some insects, that hosts endosymbiotic bacteria.Bacteriomes contain specialized cells, called bacteriocytes, that provide nutrients and shelter to the bacteria while protecting the host animal.
Characteristics of nutritive cells: Nutritive cells exhibit dynamic features such as enriched cytoplasm, fragmented vacuoles, hypertrophied nucleus and nucleolus, and abundant cell organelles. They contain elevated levels of carbohydrates, lipids, soluble sugars, and proteins, along with intense phosphatase activity.
Insects can be identified by examining the type of food and the character of the damage done in the absence of the insect itself, which helps determine what type of control is needed. Having an insect specimen and accurately identifying it can lead to eradication, and ultimately, prevention. [citation needed] Foods commonly infested include:
