Pederin

Definition

A powerful toxin and DNA inhibitor produced by some species of Paederus (Paederinae) and their endosymbionts, primarily circulating in the hemolymph. It is transferred to eggs and subsequent life stages, making it a potent defensive secretion against predators.

Etymology

The term 'pederin' is derived from the genus name 'Paederus', which comes from the Greek word 'paideros', meaning 'fond of children', likely referring to the beetles' small size, not from Latin.

Example

Pederin is a potent toxin found in the hemolymph of Paederus beetles.

Usage Notes

Pederin's primary role seems to be in defense against predators, but its impact on vertebrate predators is unclear.
