Prostaglandins: Their role in egg-laying of the cricket Teleogryllus commodus

Abstract
Mating of the T. commodus female causes increased oviposition mediated by PGE2 [prostaglandin E2], which is synthetized in the female''s spermatheca from the precursor, arachidonic acid, in the presence of a PG[prostaglandin]-synthesizing complex. The latter, together with sperm, is transferred from the male to the female via a spermatophore. Only nanogram quantities of PGE2 injected into the oviduct are necessary to simulate mating-induced egg release.
