Jail baits: how and why nymphs mimic adult females of the German cockroach, Blattella germanica
ANIMAL BEHAVIOUR, 78(5), 1097–1105.
Contributors: D. Eliyahu n, n, K. Mori & C. Schal n
author keywords: Blattella germanica; German cockroach; nuptial gift; nymph; sex pheromone; sexual mimicry

Identification of cuticular lipids eliciting interspecific courtship in the German cockroach, Blattella germanica
NATURWISSENSCHAFTEN, 95(5), 403–412.
Contributors: D. Eliyahu n, n, S. Capracotta n, D. Comins n & C. Schal n
author keywords: Blatta orientalis; contact pheromone; methyl ketone; 11-methylheptacosan-2-one; 27-oxo-11-methylheptacosan-2-one
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.
