Identification of cuticular lipids eliciting interspecific courtship in the German cockroach, Blattella germanica

NATURWISSENSCHAFTEN, 95(5), 403–412.

By: D. Eliyahu n, S. Nojima n, S. Capracotta n, D. Comins n & C. Schal n

Contributors: D. Eliyahu n, S. Nojima n, S. Capracotta n, D. Comins n & C. Schal n

MeSH headings : Animals; Blattellidae / physiology; Female; Germany; Male; Pheromones / physiology; Reproduction; Sexual Behavior, Animal / physiology
TL;DR: It is proposed that several characteristics of their mating system—chiefly, absence of closely related species in the anthropogenic environment, resulting in relaxation of selection on sexual communication, and a highly male-biased operational sex ratio—have driven males to respond with extremely low thresholds to a wide spectrum of related compounds.
