Entomophagy is widespread among many animals, including non-human primates. [3] Animals that feed primarily on insects are called insectivores . Insects, [ 4 ] nematodes [ 5 ] and fungi [ 6 ] that obtain their nutrition from insects are sometimes termed entomophagous , especially in the context of biological control applications.
The anthropologist Marvin Harris has suggested that the eating of insects is taboo in cultures that have other protein sources which require more work to obtain, such as poultry or cattle, though there are cultures which feature both animal husbandry and entomophagy. Examples can be found in Botswana, South Africa and Zimbabwe where strong ...
The true flies include several families of parasitoids, the largest of which is the Tachinidae (some 9,200 species [26]), followed by the Bombyliidae (some 4,500 species [26]), along with the Pipunculidae and the Conopidae, which includes parasitoidal genera such as Stylogaster. Other families of flies include some protelean species. [38]
[20] [5] In classical biological control, there are two demonstrated examples of potential use of entomopathogenic fungi against exotic insect species affecting agriculture. The oldest example is the use of Entomophthora maimaiga against the Spongy moth (Lymantria dispar) in the United States during early 1900s. The spongy moth was introduced ...
Interference competition, in which species compete directly, can also occur. For example, a steinernematid species that infects a host first usually excludes a heterorhabditid species. The mechanism for this superiority may be antibiotics produced by Xenorhabdus, the symbiotic bacterium of the steinernematid. These antibiotics prevent the ...
Most of these species occur in the tropics and sub-tropics, and the structures of the galls are diagnostic of the species involved. [57] A radiation of thrips species seems to have taken place on Acacia trees in Australia; some of these species cause galls in the petioles , sometimes fixing two leaf stalks together, while other species live in ...
No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions. In English, the term "locust" is used for grasshopper species that change morphologically and behaviourally on crowding, forming swarms that develop from bands of ...
Those who study entomology are known as entomologists. 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, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British ...
