Bees, Please: Stop Dying in Your Martian Simulator Gland
Odorant-binding proteins OBPs and chemosensory proteins CSPs mediate both perception and release of chemical stimuli in insects. Using a proteomic approach, we have investigated the expression of OBPs and CSPs in the mandibular glands of Herisau massage south honey bees in relation to caste and age. OBP13 is mostly expressed in young individuals and in virgin queens, while OBP21 is abundant in older bees and is prevalent in mated queens.
We have expressed Gland bee ads online of the most represented OBPs and studied their binding properties. OBP13 binds with good specificity oleic acid and some structurally related compounds, OBP14 is better tuned to monoterpenoid structures, while OBP21 binds the main components of queen mandibular pheromone as well as farnesol, a compound used as a trail pheromone in the honey bee and other hymenopterans.
The high expression of different OBPs in the mandibular glands suggests that such proteins could be involved in solubilization and release of semiochemicals.

One of the components of the sting pheromone 2 has been identified as isoamyl acetate which releases strong alarm behaviour in bees. When filter paper treated with isoamyl acetate is placed at the hive entrance the bees nearby become alerted and greatly agitated.
They assume a characteristic aggressive posture and run jerkily in Virgin hair Unterstrass or short zigzags preferentially toward the paper. The same behaviour can be observed when mandibular glands or crushed heads of worker bees are presented at the hive entrance. ❶Normal and abnormal observed fecal contents of healthy bees and bees taken from CCD colonies.

Excursus NG: The Scent Gland (Nasanov Gland) of Honey Bees
Hymenopteran venom glands are epidermal glands that have evolved from female accessory reproductive glands. In the honey bee, Apis mellifera L. A Glajd bee venom Gland bee ads online is a simple, long, thin, distally bifurcated structure, opening into an ovoid reservoir.
Along most of the length of the gland are similar secretory units that have four major Glad secretory cells, duct cells, ducts, and end apparatusesexcept in the part of the gland proximal to the venom reservoir, Chinese nanny Munsingen the secretory units resemble those around the venom reservoir.
In the latter secretory units a funnel structure occurs between the duct which is shorter than that of the secretory units of the gland and the end apparatus. This funnel may be important in protecting the secretory cells around the reservoir from the cytolytic activity Gland bee ads online be complex chemical mixture constituting the venom.
