Bees in the genus Colletes make their brood cells in the ground and coat them with a highly resistant, waterproof, transparent membrane. This membrane is a polyester constructed mainly from 18-hydroxyoctadecanoic acid and 20-hydroxy-eicosanoic acid, which are stored as their corresponding lactones in the Dufour's gland of the bee. When lining the cells, the bee secretes its glandular content, and the membrane is apparently a product of polycondensation reaction of its contents. This appears to… 

Anthophora Bees: Unusual Glycerides from Maternal Dufour's Glands Serve as Larval Food and Cell Lining

The Dufour's gland of Anthophora abrupta, a solitary bee, secretes a complex mixture of liquid triglycerides containing one long-chain and two shortchain fatty acids. This is applied inside the

Synthesis of 18-octadecanolide, a major constituent of dufour’s gland secretion ofColletes bees

Abstract18-Octadecanolide, a major constituent of Dufour’s gland secretion ofColletes bees, was synthesized by polymerization followed by depolymerization of 18-hydroxyoctadecanoic acid which in turn

Exocrine secretions of bees

The volatile components of Dufour's gland extracts were analyzed in four species of NearcticNomia bees and a series of esters were identified, two of which are new natural products reported for bees.

The volatile chemicals, detectable by coupled capillary gas chromatography-mass spectrometry, in the nest cell linings of four species in the bee generaColletes, Andrena, andLasioglossum are

Exocrine secretions of bees

The volatile components of the Dufour's gland extracts of Dufourea novaeangliae were analyzed by gas chromatography-mass spectroscopy and a series of five bis-homologous unsaturated ketones were identified, all new natural products reported for bees.

Chemistry of the Dufour's gland secretions of North American andrenid bees (Hymenoptera: Andrenidae)

The volatile components of the Dufour's gland secretions were examined in 22 Nearctic species of andrenid bees representing 10 subgenera. Farnesyl hexanoate was the dominant component in the

Macrocyclic lactones and isopentenyl esters in the Dufour's gland secretion of halictine bees (Hymenoptera: Halictidae)

The volatile components of the Dufour's gland secretion of female halictid bees have been examined in 18 Nearctic species and a series of eight esters containing branched C5-alkenols and fatty acids has been identified in several species.

A comparative study of the exocrine products of cleptoparasitic bees (Holcopasites) and their hosts (Calliopsis) (Hymenoptera: Anthophoridae, Andrenidae)

The cephalic secretion of females of the cleptoparasitic beeHolcopasites calliopsidis contains two main volatiles, 6-methyl-5-hepten-2-one and geranyl acetone. The mandibular gland secretion of its




A chloroform-soluble, neutral wax was isolated from the leaves of Colorado spruce, collected during fall and winter months. The wax was found to consist of sabinic, 14-hydroxytetradecanoic, and

Some Properties of the Nest-Building secretions of nomia, Anthophora, Hylaeus and Other Bees

Preliminary examinations of melting points, solubilities, and infrared spectra of the nest-building secretions (cell or nest linings) of Hylaeus cressoni, Nomia melanderi and Anthophora occidentalis

Behavior of the Alkali Bee, Nomia melanderi, within the Nest (Hymenoptera: Halictidae)

Nest-making behavior by this nomiine bee was generally similar to that of halictine bees, but nests in the observation chambers were deeper than those in nature and had fewer cells.

Linalool in mandibular gland secretion ofColletes bees (Hymenoptera: Apoidea)

Uinalool was identified as the main component of the mandibular gland secretion in females and males of four species ofColletes bees, and was shown to be the dominant volatile compound in the same gland in male C. cunicularius and female C. floralis.

Social Insect Pheromones: Their Chemistry and Function

Alarm pheromones have been identified chiefly in three subfamilies of ants and their distribution appears to be chemosystematically significant.
