Airborne Pheromones

Mammalian pheromones.

Mammalian pheromones control a myriad of innate social behaviors and acutely regulate hormone levels. Responses to pheromones are highly robust, reproducible, and stereotyped and likely involve developmentally predetermined neural circuits. Here, I review several facets of pheromone transduction in mammals, including (a) chemosensory receptors and signaling components of the main olfactory epit...

Human Pheromones

Tick pheromones.

According to their activity profiles tick pheromones can be characterized as assembly pheromones, aggregation/attachment pheromones, pre-attachment or pre-feeding pheromones, attractant sex pheromones, contact sex pheromones, fecundity-reducing pheromone and various ungrouped pheromones. This paper gives a short review of the chemical characteristics, biological roles, and activity periods as w...

Insect pheromones.

The evidence for intraspecies chemical communication in insects is reviewed, with emphasis on those studies where known organic compounds have been implicated. These signal-carrying chemicals are known as pheromones. There are two distinct types of pheromones, releasers and primers. Releaser pheromones initiate immediate behavioral responses in insects upon reception, while primer pheromones ca...

Chiral methyl-branched pheromones.

Insect pheromones are some of the most interesting natural products because they are utilized for interspecific communication between various insects, such as beetles, moths, ants, and cockroaches. A large number of compounds of many kinds have been identified as pheromone components, reflecting the diversity of insect species. While this review deals only with chiral methyl-branched pheromones...
