“…and, as this paper has shown, larger males often provide larger spermatophores with more sperm. Studies show that female Orthoptera that mate with larger males, can have higher fecundity (Gwynne et al 1984;Honěk 1993;Brown 1997;Fedorka & Mousseau 2002), or produce larger offspring (Bretman et al 2006;kosal & niedzlek-Feaver 1997kosal & niedzlek-Feaver , 2007Saleh et al 2013). In contrast, larger individuals may require more food, be more conspicuous and less agile, and suffer higher predation rates (Whitman & Vincent 2008).…”

Chemical Identification, Emission Pattern and Function of Male-Specific Pheromones Released by a Rarely Swarming Locust, Schistocerca americana

Pheromones serve key functions in the biology of swarming locusts. However, research has focused largely on the mass-swarming desert locust, Schistocerca gregaria. We extended these investigations to the pheromonal profile of the rarely swarming American bird grasshopper, S. americana (Drury). The headspace of mature gregarious S. americana males contained three characteristic electroantennogram-active components: (Z)-3-nonen-1-ol, (Z)-2-octen-1-ol, and nonanal. These substances were accompanied by aromatics such as phenol that are also released by females and immatures. Male-specific pheromone components were released independently from epidermal gland cells, with the highest emission rate being for (Z)-3-nonen-1-ol from the abdomen and legs. The emission of the major compound, (Z)-3-nonen-1-ol, is stress-sensitive, and coincides with sexual maturity and crowding. The emission pattern strongly supports a role of (Z)-3-nonen-1-ol in the reproductive biology of S. americana. The pheromone is involved in courtship-inhibition and is used as mate assessment pheromone in cryptic female choice. In double mating experiments, females choose sperm of males with high (Z)-3-nonen-1-ol emission. Furthermore the pheromone accelerated maturation of immature adults and supports synchronization of sexual development.
