Chemistry of the American cockroach pheromone

Pheromone detection by a pheromone emitter: a small sex pheromone-specific processing system in the female American cockroach.

Many animals depend on pheromone communication for successful mating. Sex pheromone in insects is usually released by females to attract males. In American cockroaches, the largest glomerulus (B-glomerulus) in the male antennal lobe (first-order olfactory center) processes the major component of sex pheromone. Using intracellular recordings combined with fine neuroanatomical techniques, we prov...

The American Cockroach Regeneration

john steinbeck: friend of the american common man

in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...

Circadian Rhythm in Sex Pheromone Communication in American Cockroach, Periplaneta Americana L

The circadian rhythm of American cockroach response to sex pheromone was investigated in behavio-ral and electroantennographic tests. Obvious daily changes in behavioral responses of males to synthetic Periplanone B, one of the main components of the female sex pheromone, were not paralleled by concomitant electroantennogram fluctuations. These observations suggest that responses of pheromone r...

A pheromone-binding protein from the cockroach Leucophaea maderae: cloning, expression and pheromone binding.

Odorant-binding proteins (OBPs) are thought to transport volatile compounds from air to their receptors through the sensillary lymph. In this protein family, the subgroup of pheromone-binding proteins (PBPs) is specifically tuned to the perception of the sexual pheromone. To date, the description of OBPs has been restricted to Endopterygota and Paraneoptera. Their expression in Orthopteroid has...
