Only the female mosquito feeds on humans, and she needs a blood meal in order to produce eggs. During a feeding, the female mosquito bites the human skin, and injects saliva. The saliva contains various proteins that prevent the blood from clotting, as well as proteins that keep the blood flowing into the mosquito’s mouth. | | | All About Mosquito Allergy | Many of the mosquito saliva proteins can cause immune reactions, including allergic reactions. Typically, however, most people have a variety of reactions to mosquito bites, and the symptoms change over time, depending on the amount of bites a person received. These reactions can include both immediate and delayed swelling and itching around the bite area. These reactions tend to decrease in frequency after being bitten by mosquitoes over many years. | | | | All About Fire Ant Allergy | The imported fire ant (IFA) is a type of stinging ant that was accidentally imported into the United States from South America in the early 1900s. Since their introduction into the port of Mobile, Alabama, IFAs have spread into much of the southeastern United States and Texas. | | | | Allergy to Scorpion Stings | Scorpions are found around the world. They are not insects; they are arachnids, and are closely related to spiders, mites and ticks. Scorpions have the ability to kill prey by injecting venom from a stinger located at the end of a long tail. Because many scorpions are found indoors, people are frequently stung by scorpions. The common striped scorpion, Centruroides vittatus, is the most commonly encountered scorpion in the United States. | | | | | | You are receiving this newsletter because you subscribed to the About Allergies newsletter.
