چکیده
D ufour G land, Harpagoxenus, Heptadecane, (£)-ß-Farnesene, Homofarnesene The volatile components of tlic Dufour gland sccrcticn of wcrlvcrs cf t*!C eint arpoxeni+s sublaevis have been analysed by gas chromatography and mass spectrometry. Over 20 compo nents have been identified, consisting of linear and terpenoid hydrocarbons. Each gland contains approximately 6 ng of hydrocarbons with n-heptadecene (40%) and /i-heptadecadiene (30%) as the m ajor components. Two terpenoid hydrocarbons, (-E)-ß-farnesene and a homofarnesene isomer were also identified.

Morphology and Chemical Contents of Dufour Glands of Pseudomyrmex Ants (Hymenoptera: Formicidae)
The morphology and ultrastructure of the Dufour gland of a pseudomyrmecine ant is de scribed. The gland has an unusually large volume but possesses a very thin epithelial lining. Its morphology does not constitute a specific subfamily character as in some ant subfamilies. Analysis by gas chromatography-mass spectrometry of the glands of three species showed them all to be rich in saturated lin...
متن کاملExocrine chemistry of the myrmicine ant Zacryptocerus pusillus (Hymenoptera: Formicidae).
Minor workers of the ant Zacryptocerus pusillus have unusual exocrine secretions in both their mandibular and Dufour glands. The mandibular glands contain a 3:1 mixture of 4-heptanone and 4-heptanol, a mixture found only in the related species Z. varians. The Dufour gland contains a mixture of 13 aldehydes from C9 to C18, not previously encountered in ant secretions. The venom glands gave varia...
متن کاملBehavioral and olfactory antennal responses of Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) workers to their dufour gland secretion.
Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was ...
متن کاملForaging behavior in the ant genus Messor (Hymenoptera: Formicidae: Myrmicinae)
The genus Messor consists of 113 species of seed harvesting ants that are found in grasslands, semi-arid areas and savannahs in both the Old and New World. A full spectrum of foraging strategies occurs in Messor, ranging from individual to group foraging, with the latter having evolved several times. This paper reviews foraging strategies and the underlying behavioral mechanisms found in specie...

The morphology and fine structure of the convoluted gland inside the venom reservoir of the ponerine ant Dinoponera austrafis (Hymenoptera : Formicidae) are described. The cells of the convoluted gland can be divided into 3 major groups: (1) epithelial cells, (2) glandular cells with end apparatus secreting into the tubule inside the convoluted gland, and (3) glandular cells with end apparatus ...
