caption_attribution_description: English: (A) Photomicrograph of sting apparatus components -Dufour's gland (DG), poison gland/sac (PG), and sting in the worker. (B) Proposed pathway of trail pheromone biosynthesis in the worker. (C) SolinPBAN induces trail pheromone biosynthesis after SolinPBAN injection into workers. DGs were dissected from adult workers 6 h after SolinPBAN or saline (control) injection. The mean production of pheromone increased more than 30 ng (&gt;19%) per ant after SolinPBAN injection. Data were analysed by two-tailed unpaired t-test (P = 0.0054, n≥35)
context_page_description: Dufour's gland is an abdominal gland of certain insects, part of the anatomy of the ovipositor or sting apparatus in female members of Apocrita. The diversification of Hymenoptera took place in the Cretaceous and the gland may have developed at about this time as it is present in all three groups of Apocrita, the wasps, bees and ants.
