Insect bites and stings Insect bites and stings Insect bites and stings occur when an insect is agitated and seeks to defend itself through its natural defense mechanisms, or when an insect seeks to feed off the bitten person. Some insects inject formic acid, which can cause an immediate skin reaction often resulting in redness and swelling in the injured area. Stings from fire ants, bees, wasps and hornets are usually painful, and may stimulate a dangerous allergic reaction called anaphylaxis for at-risk patients, and some wasps can also have a powerful bite along with a sting. Bites from mosquitoes and fleas are more
Insect development during storage development. However, quiescence acts like an anesthetic, and stops insect development for a short time by slowing down insect metabolic activity. It is induced by a sudden drop in temperature that ranges from 0 °C to 10 °C. A simulation of insects chilling in a morgue was conducted by using "Calliphora vicina" to illustrate that adult emergence is delayed by 24 hours, no matter in which stage the refrigeration occurred. There was no mortality when they were kept at 3 °C for 24 hours. In this simulation, quiescence was induced by the low temperature and the insect physiology was not
