Neryl decanoate: female sex pheromone of the click beetle <i>Dalopius marginatus</i>

Sex Pheromone of the Mealworm Beetle

Sex pheromone activity from female medwonn beetles (Tenebrio molitor) may be extracted and quantified by fractional population response of virgin adult males, which attempt copulation with any pheromone-treated object. Extracts of mature males can be shown to elicit identical behavioral activity, although at lower individual concentration. Since response to the pheromone is sex-specific, its ap...

Intraspecific Variation in Female Sex Pheromone of

The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This pest is often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on the sexual communication system of codling moth, as male and female moths will persist in their attempt ...

Mating Disruption of Oriental Beetle with Sprayable Sex Pheromone Formulations

Identification of a female sex pheromone in Carcinus maenas

Despite major progress in our understanding of animal signaling systems, the identification of chemical signals in aquatic organisms is still in its infancy. Exemplary for this is the lack of structural knowledge of crustacean sex pheromones despite their initial description in crabs almost 40 yr ago. We hypothesized that species in which the reproductive event is linked to a short window of ma...

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...
