What poisonous insects are there?

Question 1: Which insects are poisonous? Insects are the most diverse animals on the earth, most of which have no direct relationship with human beings, but a few have always had a subtle relationship with human beings. Because humans and insects often compete for the same thing in the same time and space, the war between humans and insects has never stopped. An animal or plant is called a poisonous animal or a poisonous plant because there is a substance in its body that contacts or enters the human body in a certain way and accumulates to a certain extent, which will weaken or damage the human body function, cause pathological changes in organs and tissues, and cause health damage or death. Insects that cause poisoning can be called poisonous insects. Insects secrete or release venom to attack humans or other animals for self-protection, among which bees, salamanders and caterpillars are well known. Because insects often release venom in different ways to cause pain or disease in animals, the following are classified according to the different ways of venom release.

(a) contact-contact with the human body, local itching, fever and other symptoms.

For example: poisonous moths, green onions, paederus, etc.

(2) Spray-spray venom when disturbed.

For example: walking bugs.

(3) Drilling-injecting venom into human body with mouthparts.

For example: mosquitoes, gnats, flies, insect-eating beetles, bed lice and so on.

(4) Tapping-piercing human skin with needle-like tissue at the end of abdomen and injecting venom.

For example: bees, wasps, etc.

(5) Swallowing-swallowing poisonous insects by mistake or using them as food often brings their venom into the body to cause poisoning.

Examples of poisonous insects

(1) Huang Ruixiang

Huang Ruixiang, commonly known as gallbladder or banyan tree, can be used as medicine, but improper or excessive use will cause poisoning.

Toxic parts: Ficus carica in Gracilaria mainly exists in gonads, blood and internal organs, and body fluids containing Ficus carica can also be secreted at the ends of leg joints.

Poisoning symptoms: the main toxic substance of Daphne giraldii is poison baneline. Contact with skin or mucous membrane may cause local symptoms; Excessive oral or external use can cause systemic poisoning symptoms and even death due to acute renal failure after absorption.

(2) Take Meloidogyne incognita as an example.

Poisonous parts: since the second instar, there are four black spots on the first to eighth abdominal segments of the larvae, and a pair of hairy tumor poisonous hairs are raised on the black spots, with barbed short tips, hollow tubes inside and poisonous gland cells below, containing yellowish venom.

Poisoning symptoms: human contact with its venom will cause dermatitis, mainly chemical * * *, because its venom is strongly acidic (pH 1~2), but physical mechanism cannot be ruled out.

(3) Ranidae

Poisonous parts: the bristles on the larvae are connected with poisonous glands, which are easy to fall off and fly with the wind. After bristles contact human skin, venom is injected into human skin, causing dermatitis to varying degrees.

Poisoning symptoms: the local manifestations are mainly swelling and pain, which subsides within a few days, and the severe cases last for several months.

(4) bees

Bees can be considered as beneficial insects. Besides honey for human consumption, propolis and royal jelly also have many uses.

Poisonous parts: The ovipositor tube at the end of worker bees' abdomen is specialized as a barb, which communicates with the poisonous glands in the body. After stinging, venom is injected into the human body, causing poisoning. Because there are barbs, some thorns will stay in people's wounds.

Poisoning symptoms: Bee venom mainly contains formic acid and protein. After being stung, the clinical manifestations are redness, swelling, heat, pain and itching. Those with mild symptoms can recover in a short time, and those with severe symptoms will die of respiratory paralysis. People who are allergic to bee venom, even a small amount of bee venom, will cause allergic shock and coma.

(5) wasps

Wasps are often called tiger bees or wasps. Tourists accidentally disturb wasps when they go to the wild, and there are many examples of bee stings.

Poisonous part: There is a long and thick thorn at the end of the abdomen of the female bee, which communicates with the poisonous gland and has no barb.

Poisoning symptoms: the venom is alkaline and mainly contains histidine and IgE. The poisoning reaction is faster and more serious than that of bees. Allergic people will have difficulty breathing, convulsions, even shock and coma, and a few people may die because of the toxic effects of bee venom on heart, kidney and liver.

(6) paederus

Paederus is mostly found in summer, with a small body, less than 1 cm in length and only 0. 1 to 0.2 cm in width.

Toxic parts: Body fluids contain * * * toxic substances, which will not intentionally hurt or sting people.

Poisoning symptoms: Venom will cause inflammation and erosion when it comes into contact with skin. As long as it is not contaminated by a large amount of venom, the damage to the skin is usually only superficial.

Wu Jieshan pointed out that you should never apply ointment or clean it with improper solution or medicine. Someone once applied incense ashes and herbs to damaged skin, which led to secondary bacterial infection and more serious skin damage.
