Dufour's gland

Dufour's gland An abdominal gland found in the females of nearly all Apocrita. It empties at the base of the ovipositor or sting, and is thought in many groups to lubricate the valves of the ovipositor during egg-laying. In worker ants it secretes either alarm or trail-making pheromones. It is massively developed in most solitary mining bees, and produces secretions to make a waterproof, fungus-resistant lining for brood cells. In at least two bee families (Anthophoridae and Megachilidae) the Dufour's gland secretion is also a dietary supplement for the developing larva, and is added to the pollen and nectar stored by the female before egg-laying.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
