2011 journal article

Unusual macrocyclic lactone sex pheromone of Parcoblatta lata, a primary food source of the endangered red-cockaded woodpecker

Proceedings of the National Academy of Sciences, 109(8), E490–E496.

By: D. Eliyahu n, S. Nojima n, R. Santangelo n, S. Carpenter*, F. Webster*, D. Kiemle*, C. Gemeno n, W. Leal *, C. Schal n 

author keywords: pheromone monitoring; surveillance; wildlife conservation
MeSH headings : Animals; Arthropod Antennae / physiology; Birds / physiology; Chromatography, Gas; Cockroaches / metabolism; Endangered Species; Female; Food; Lactones / metabolism; Macrocyclic Compounds / metabolism; Magnetic Resonance Spectroscopy; Mass Spectrometry; Sex Attractants / analysis; Sex Attractants / chemistry
TL;DR: Parcoblattalactone was biologically active in electrophysiological assays and attracted not only P. lata but also several other Parcoblatta species in pine forests, underscoring its utility in monitoring several endemic wood cockroach species in red-cockaded woodpecker habitats.

2009 journal article

Jail baits: how and why nymphs mimic adult females of the German cockroach, Blattella germanica

ANIMAL BEHAVIOUR, 78(5), 1097–1105.

By: D. Eliyahu n, S. Nojima n, K. Mori & C. Schal n 

Contributors: D. Eliyahu n, S. Nojima n, K. Mori & C. Schal n 

author keywords: Blattella germanica; German cockroach; nuptial gift; nymph; sex pheromone; sexual mimicry
TL;DR: The results support the interpretation that nymphs engage in sexual mimicry to gain access to male-produced nuptial tergal secretions that are exposed and can be secured only during courtship. (via Semantic Scholar)

2008 journal article

Cuticular hydrocarbons as maternal provisions in embryos and nymphs of the cockroach Blattella germanica

JOURNAL OF EXPERIMENTAL BIOLOGY, 211(4), 548–554.

By: Y. Fan n, D. Eliyahu n & C. Schal n 

Contributors: Y. Fan n, D. Eliyahu n & C. Schal n 

author keywords: cuticular hydrocarbons; maternal investment; waterproofing; communication; cockroach; Blattella germanica
MeSH headings : Animals; Cockroaches / embryology; Cockroaches / metabolism; Hydrocarbons / metabolism; Integumentary System / physiology; Nymph / metabolism
TL;DR: Results show, for the first time in any insect, that a mother provides a significant complement of her offspring's cuticular hydrocarbons. (via Semantic Scholar)

2008 journal article

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 

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.

2008 journal article

New contact sex pheromone components of the german cockroach, Blattella germanica, predicted from the proposed biosynthetic pathway

JOURNAL OF CHEMICAL ECOLOGY, 34(2), 229–237.

By: D. Eliyahu n, S. Nojima n, K. Mori & C. Schal n 

Contributors: D. Eliyahu n, S. Nojima n, K. Mori & C. Schal n 

author keywords: 27-Oxo-3; 11-dimethylheptacosan-2-one; 27-Hydroxy-3; 11-dimethylheptacosan-2-one; sex pheromone; Blattella germanica; german cockroach; methyl ketone; alcohol; aldehyde
MeSH headings : Alcohols / analysis; Alcohols / metabolism; Alcohols / pharmacology; Aldehydes / analysis; Aldehydes / metabolism; Aldehydes / pharmacology; Animals; Blattellidae / physiology; Chromatography, High Pressure Liquid; Female; Gas Chromatography-Mass Spectrometry; Ketones / analysis; Ketones / metabolism; Ketones / pharmacology; Male; Sex Attractants / analysis; Sex Attractants / metabolism; Sex Attractants / pharmacology; Sexual Behavior, Animal / drug effects
TL;DR: It is shown that the epicuticle of the German cockroach does indeed contain these two compounds, 3,11-dimethylheptacosan-2-one and 27-oxo-3, 11-dimethyltestosterone-1-one, and that the contact sex pheromone of the female Germany cockroach, thus may consist of at least six biosynthetically related components.

2004 journal article

Behavioral activity of stereoisomers and a new component of the contact sex pheromone of female German cockroach, Blattella germanica

JOURNAL OF CHEMICAL ECOLOGY, 30(9), 1839–1848.

By: D. Eliyahu n, K. Mori *, H. Takikawa *, W. Leal * & C. Schal n 

author keywords: contact sex pheromone; stereoisomers; German cockroach; behavioral assay; 3,11-dimethylnonacosan-2-one; 3,11-dimethylheptacosan-2-one
MeSH headings : Alkanes / chemistry; Alkanes / pharmacology; Animals; Cockroaches / drug effects; Cockroaches / physiology; Dose-Response Relationship, Drug; Female; Ketones / chemistry; Ketones / pharmacology; Male; Sense Organs / physiology; Sex Attractants / chemistry; Sex Attractants / pharmacology; Stereoisomerism
TL;DR: It is confirmed that synthetic (3S,11S)-3,11-dimethylheptacosan-2-one elicits behavioral responses, but less so than its C29 homolog. (via Semantic Scholar)
