Polistes annularis (P. annularis) is a species of paper wasp found throughout the eastern half of the United States. [1] [2] This species of red paper wasp is known for its large size and its red-and-black coloration and is variably referred to as a ringed paper wasp or jack Spaniard wasp.
Polistes rubiginosus and P. carolina are the only large red-coloured wasp species in the eastern US. [7] P. rubiginosus is, however, extremely similar to P. carolina, [1] [6] [7] and can be found in the same regions; [4] [6] [7] the key morphological difference being the malar area (the "cheek") seen from the side, but this works only for the ...
Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting. [3]: 450 First aid for fire ant bites includes external treatments and oral medicines. [citation needed] External treatments: a topical steroid cream (hydrocortisone), or one containing Aloe vera [4]
Feeding bites may also contain digestive enzymes, as in spiders; spider bites have primarily evolved to paralyse and then digest prey. A sting comes from the abdomen; in most insects (which are all largely hymenopterans), the stinger is a modified ovipositor, [16] which protrudes from the abdomen. The sting consists of an insertion wound, and ...
The stings of the red imported fire ant in animals are painful, and may prove life-threatening. [70] In dogs, stings from the red imported fire ant can cause pustular dermatosis, a condition where pustules appear in crops as a result of the ant sting. [71] After getting stung, the immediate response consists of erythema and swelling.
Topical tobacco paste is a home remedy sometimes recommended as a treatment for wasp, hornet, fire ant, scorpion or bee stings, [1] though there is no scientific evidence that this home remedy works to relieve pain. [2] For about 2 percent of people, allergic reactions can be life-threatening and require emergency treatment. [citation needed]
A heat pen has a ceramic or metal plate at the tip, which heats to 50 to 60 °C. The heated plate is brought into contact with the area of skin affected by the insect bite for 3 to 10 seconds, causing the skin to briefly heat up to 53 °C (local hyperthermia). The heat activates various physiological processes.
The duration of the sting pain can range anywhere from one minute (such as the sting of the red paper wasp) to half an hour (such as the sting of the velvet ant). [2] [3] Wasp venom uniquely contains kinin. One of the kinins found in wasp venom, "polistes kinin 3", is found to lead to similar effects on smooth musculature and circulation as ...
