“…These authors report that the compound is stable in boiling water, but without specific citation. The statement is probably based on rather old work (Netolitzky 1919;Pawlowsky & Stein 1929;Ito 1933) describing injuries to the skin after application of boiled beetles or of extracts of them. This condition could result from the presence of small amounts of pederin that resisted boiling, or from other substances with a similar biological activity and unaffected by heating.…”

Biosynthesis of the defensive compound pederin by females in the genus Paederus appears to be associated with endosymbiotic microorganisms. In P. melanurus, which could be maintained in the laboratory for several generations, horizontal transmission occurs by ingestion of eggs inoculated with the specific endosymbionts. They are responsible for females' pederin polymorphism. Heating or freezing eliminated or markedly reduced transmission. This indicates bacteria that are unable to produce endospores and lacking a cell wall. Influences other than pederin biosynthesis could not be observed.
