Crickets are efficient at converting their food into body mass, making them a candidate for food production. They are used as human food in Southeast Asia, where they are sold deep-fried in markets as snacks. They are also used to feed carnivorous pets and zoo animals. In Brazilian folklore, crickets feature as omens of various events.
As with other livestock animals, a variety of welfare concerns can manifest during the rearing and slaughter of insects. The 5 Domains framework can be used to broadly categorize these areas of possible concern into four functional domains (nutrition, environment, behavior, and physical health) which then influence the mental domain of the animal's welfare state.

Ormia ochracea is a small yellow nocturnal fly in the family Tachinidae. [2] It is notable for its parasitism of crickets and its exceptionally acute directional hearing. The female is attracted to the song of the male cricket and deposits larvae on or around him, as was discovered in 1975 by the zoologist William H. Cade.
A perspective on the evolutionary options can be gained by considering four questions: the effect on the reproductive fitness of a parasite's hosts; the number of hosts they have per life stage; whether the host is prevented from reproducing; and whether the effect depends on intensity (number of parasites per host). From this analysis ...
Any food around a dense group of crickets will be gone quickly, Lorch said. And behind every cricket is another hungry cricket with giant mandibles, ready to take a meal. So Mormon crickets march ...
Gordius robustus, a species of horsehair worm, is a parasite of the Mormon cricket, [11] as is Ooencyrtus anabrivorus. [12] The most common chemical control method used is carbaryl (typically sold as "Sevin Dust") bait. This bait kills both the Mormon crickets that eat the bait and the crickets that eat crickets that have eaten the bait.
That’s because cicadas have a high probability of carrying parasites, bacteria and viruses, says Czerwony. But boiling, frying or sautéing them will kill the contaminants and reduce the risk of ...
A fish parasite, the isopod Cymothoa exigua, replacing the tongue of a Lithognathus. Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life.
