Entomology (from Ancient Greek ἔντομον (entomon) 'insect' and - λογία ( -logia) 'study') [1] is the scientific study of insects, a branch of zoology. In the past the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids ...
Ant. Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified.
Bed bug. Bed bugs are parasitic insects from the genus Cimex, who are micropredators that feed on blood, usually at night. [ 7] Their bites can result in a number of health impacts, including skin rashes, psychological effects, and allergic symptoms. [ 5] Bed bug bites may lead to skin changes ranging from small areas of redness to prominent ...
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.

Insects that feed on or parasitise other insects are beneficial to humans if they thereby reduce damage to agriculture and human structures. For example, aphids feed on crops, causing economic loss, but ladybugs feed on aphids, and can be used to control them. Insects account for the vast majority of insect consumption. [173] [174] [175]
Adult wasps at normal speed. Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps ( Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from ...
