Wasp venom is a complex substance produced by certain species of wasps for defense and predation. It typically contains a variety of bioactive compounds that serve different purposes:
-
Neurotoxins: These target the nervous system of the prey or predator, causing paralysis or pain. They are effective against insects and can also deter larger animals.
-
Cytolytic toxins: These toxins break down cells by disrupting their membranes, leading to tissue damage and inflammation. They help in digesting prey or deterring predators.
-
Vasoactive toxins: These affect blood vessels, causing changes in blood pressure and circulation. They can contribute to pain and inflammation at the site of a sting.
-
Allergens: Some people are allergic to wasp venom, which can lead to severe reactions such as anaphylaxis. These allergens trigger an immune response that can be life-threatening in sensitive individuals.
-
Pheromones: Wasps use certain chemicals in their venom as pheromones to communicate with each other, marking territories or signaling danger.
The exact composition of wasp venom varies between species, and even within species, depending on factors like diet, environment, and individual variability. The primary function of venom is defensive, helping wasps protect themselves and their nests from threats.
