Pyretriroideja

Pyretriroideja is a Finnish term referring to synthetic chemical compounds that mimic the insecticidal properties of pyrethrins, natural insecticides found in chrysanthemum flowers. These synthetic analogs, known as pyrethroids, are widely used in agriculture, public health, and household pest control due to their effectiveness against a broad spectrum of insects and relatively low mammalian toxicity.

Pyrethroids are classified as neurotoxins. They work by disrupting the normal functioning of an insect's nervous system. Specifically, they affect the sodium channels in nerve cells, causing them to remain open for longer periods. This prolonged opening leads to repetitive firing of the nerves, resulting in paralysis and eventual death of the insect. Different types of pyrethroids have varying chemical structures and modes of action, leading to differences in their efficacy against specific insect species and their environmental persistence.

In Finland, as in many other countries, the use of pyrethroids is regulated to ensure safety and minimize environmental impact. They are commonly found in products such as insect sprays, mosquito repellents, and agricultural pesticides. While generally considered safer for humans and pets than older classes of insecticides, proper handling and application are still essential to avoid potential adverse effects. Environmental concerns include their toxicity to aquatic organisms, necessitating careful use near water bodies.
