 INTRODUCTION. TYPES OF AGGRESSIVE INSECTS
In this topic there are going to talk each other the stings of all the types of insects, between them two categories of aggressive insects differ:
- The poisonous ones or horse-trainers: wasps, bees, bumblebees, ants, chandeliers and scorpions.
- The parasites or teething rings: mosquitoes, gadflies, fleas, thumbtacks, mites and ticks.
And also it might differentiate three types different from reactions from the insects stings:
- The first type of reaction named intense local reaction, which is always equal, or that whenever it is stung by an insect there will appear the same reaction, which will be always local but more intense than in the rest of the persons. This type of reaction is more frequent in the persons who endure any type of allergy but he is not a necessary allergic being to have it. The fact that intense local reactions appear can be indicative of a progressive allergic sensitization.
- The second type of reaction constitutes it the persons who are really allergic to the sting of the insect in question. This type of reaction is characterized for being more intense and a major potential covers danger that the previous ones, since the person is sensitized and the reaction happens of being a place to systemic or that extends the reaction and can go so far as to cause a shock, the called anaphylactic shock. His symptoms are very variable appearing in the first 15 minutes and they include widespread hives (ronchas), angioedema (inflammation of the face and neck affecting to the airways and it produces difficulty to breathe, etc.
- A third reaction called poisonous happens in persons, to that there is inoculated a big quantity of poison as consequences of multiple stings or for the location of these. For example the stings are of special danger in head / neck, where more than 40 stings of mosquitoes or less even than wasps it can bear an important risk. Also the location of the above mentioned stings, example in eyelids, lips, etc., cause a big local reaction.
For frequency the mosquitoes stings are the causers of major numbers of problems, but there are the wasps and bees (named himenópteros) the most dangerous.
There are four flying insects, all of the order of the himenópteros, recognized as causers of allergic reactions.
They can split in:
- Véspidos (wasps, white and yellow hornets)
- Apidos (domestic bee and bumblebee - a rare aggressor).
- The ants of fire and the ants of the harvest (himenópteros ápteros) also cause systemic allergic reactions and death, and they are well-known on the beach of the Gulf of Mexico and in the Southwest of the United States, respectively. It is not a problem in Europe.
- The African - Brazilian killing, hybrid bees, they have emigrated to Texas. It is probable that his emigration towards the north remains limited by the low temperatures. In contrast with the sting of the common bee, the swarms of "killing bees" that sting to a subject (or animal) cause serious and even fatal reactions. It is not a problem in Europe.
The fundamental difference in the sting is that the apoideas (bees) die after the sting since his sting remains fixed in the victim but this in turn causes his death, without being like that with the wasps. The species of véspulas (wasps) are those who cause more reactions for stings to the being those that construct his beehive in the soil or under trunks being involuntarily invaded his territory and attack.
Nevertheless the allergic reactions appear with more frequency in the bees minders since they are the beekeepers those who after multiple stings go so far as to be sensitized.
Mosquitoes sting. Insect that more stings produce. Of summer appearance it attacks from the beginning of the twilight up to the exit of the sun, feeding sucking the blood of his victims, for which sucker crosses with his device the skin and inoculates an anticoagulant substance to be able to "absorb" the blood, be said substance the one that causes the well-known itch and the typical roncha. They are attracted by the CO2 of the breath and by chemical substances that become detached with the perspiration in addition to for the corporal temperature. His diagnosis is simple there being always appreciated the place of the sting and the typical circular or oval roncha. Only female "stings" the mosquito since the male feeds on nectar.
Fleas stings. They are easy to recognize since they sting almost in tier or groups, being pápulas (ronchas) centred by the point of the sting. The problem that it causes is more of nature sanitarily, given that they transmit illnesses with his sting.
Thumbtacks sting. There are isolated big stings that in contrast to the mosquitoes or fleas they suck of slow form up to satiating themselves increasing even several times his volume after which they become alienated remaining in the clothes or pledges of his victim to keep on stinging.
OTHER STINGS
Jellyfish and anemones
Small stings possess in his tentacles that, on having touched them, kidlings stick in the skin producing pápulas grouped in linear form. They provoke intense pain and itch. The injuries wash themselves with salt, warm water 50ºC (since the poison is termolábil) and there is applied on them alcohol of 90th or compresses of ammonia.
Fish scratches
It has a sting that produces intense pain and must be extracted. Sometimes it is necessary to apply an anesthetic one on the area.
Snakes
In our way few poisonous species exist. The symptoms depending on the inoculated poison can be: sickness, sudoración fry, reddening of the area, intense pain, fall of the tension and hemorrhages for gums and nose. His treatment is hospitable with antidotal whey.
