Pheromone Transduction in Moths
Calling female moths attract their mates late at night with intermittent release of a species-specific sex-pheromone blend. Mean frequency of pheromone filaments encodes distance to the calling female. In their zig-zagging upwind search male moths encounter turbulent pheromone blend filaments at highly variable concentrations and frequencies. The male moth antennae are delicately designed to de...
متن کاملPeripheral mechanisms of pheromone reception in moths.
Moths pheromones mostly consist of two or a few chemical components in a species-specific ratio. Each component is perceived by a particular type of receptor cell. Some pheromone components can inhibit the behavioral responses to other pheromone components. A single pheromone molecule is sufficient to elicit a nerve impulse. The dose-response curve of single pheromone receptor neurons increases...
متن کاملRole of neuropeptides in sex pheromone production in moths.
Sex pheromone biosynthesis in many moth species is controlled by a cerebral neuropeptide, termed pheromone biosynthesis activating neuropeptide (PBAN). PBAN is a 33 amino acid C-terminally amidated neuropeptide that is produced by neuroendocrine cells of the subesophageal ganglion (SEG). Studies of the regulation of sex pheromone biosynthesis in moths have revealed that this function can be eli...
متن کاملProcessing of Pheromone Information in Related Species of Heliothine Moths
In heliothine moths, the male-specific olfactory system is activated by a few odor molecules, each of which is associated with an easily identifiable glomerulus in the primary olfactory center of the brain. This arrangement is linked to two well-defined behavioral responses, one ensuring attraction and mating behavior by carrying information about pheromones released by conspecific females and ...
متن کاملAntennal lobe organization and pheromone usage in bombycid moths.
We investigated the neuroanatomy of the macroglomerular complex (MGC), which is involved in sex pheromone processing, in five species in the subfamily Bombycinae, including Ernolatia moorei, Trilocha varians, Rondotia menciana, Bombyx mandarina and Bombyx mori. The glomerulus located at the dorsal-most part of the olfactory centre shows the largest volume in moth species examined to date. Such ...
