write five sentences about a harmful insects
Answers
Many insects are considered pests by humans. Insects commonly regarded as pests include those that are parasitic (e.g. lice, bed bugs), transmit diseases (mosquitoes, flies), damage structures (termites), or destroy agricultural goods (locusts, weevils). Many entomologists are involved in various forms of pest control, as in research for companies to produce insecticides, but increasingly rely on methods of biological pest control, or biocontrol. Biocontrol uses one organism to reduce the population density of another organism—the pest—and is considered a key element of integrated pest management.[133][134]
Despite the large amount of effort focused at controlling insects, human attempts to kill pests with insecticides can backfire. If used carelessly, the poison can kill all kinds of organisms in the area, including insects' natural predators, such as birds, mice and other insectivores. The effects of DDT's use exemplifies how some insecticides can threaten wildlife beyond intended populations of pest insects.[135][136]Bed bugs, mosquitoes, horseflies, yellow flies, fleas, tsetse flies, lice, and other insects feed on humans and other animals, which can leave behind annoying and itchy bites. When these insects feed on us, they can sometimes inject deadly germs into our bloodstream that can cause serious illness and even death.
