“…Adults of female P. americana release two major active sex pheromone components, periplanone-A and periplanone-B, to solicit the male adults26. Thus, like in the lepidopterans, male antenna predominate expression is the standard to find PR1356.…”

“…It can tolerate a wide range of environments, from Arctic cold to tropical heat. Periplanone-A and periplanone-B are two major sex-pheromone components emitted from the female P. americana , which trigger strong electroantennogram responses and behavioural response of conspecific male individuals26. To avoid toxic baits, cockroaches rapidly evolved their gustatory system responsible for glucose aversion27.…”

Periplaneta americana is a notorious urban pest prevalent in human habitats; very little is known about its chemosensory mechanism. Employing the advanced next-generation sequencing technique, in the present study, we conducted transcriptome sequencing and analysis of the antennae of the adult males and females as well as their mouthparts using an Illumina platform. This resulted in the discovery of a huge number of the members of all major known chemosensory receptor families in P. americana, including 96 odorant receptors (ORs), 53 ionotropic receptors (IRs), and 33 gustatory receptors (GRs). Tissue expression profiles showed most of them mainly expressed in antennae and phylogenetic analysis demonstrated the expansion in the clade distinguishing them from other functionally well-known Lepidoptera species. A high percentage of chemosensory receptor genes (ORs in particular) showing female antenna bias in mRNA expression was observed. Our results provide a basis for further investigations on how P. americana coordinates its chemosensory receptor genes in chemical communication with environments, and for development of novel pest management approaches.

“…Additionally, moth sex pheromone components also elicited an electrophysiological response in female adults. Periplanone-A (PA) and periplanone-B (PB) are two sex pheromone components of P. americana (Okada et al, 1990). PA and PB mixtures have been shown to trigger electrophysiological responses (Nishino et al, 2011) and PB also attracted female adults (Takahashi et al, 1988), indicating that female adults of P. americana can perceive their own sex pheromone components.…”

The American cockroach (Periplaneta americana) is an urban pest with a precise chemosensory system that helps it achieve complex physiological behaviours, including locating food and mating. However, its chemosensory mechanisms have not been well studied. Here, we identified 71 putative odorant carrier protein genes in P. americana, including 57 new odorant-binding proteins (OBPs) and 11 chemosensory proteins (CSPs). To identify their physiological functions, we investigated their tissue expression patterns in antennae, mouthparts, legs, and the remainder of the body of both sexes, and determined that most of these genes were expressed in chemosensory organs. A phylogenetic tree showed that the putative pheromone-binding proteins of P. americana were in different clades from those of moths. Two genes, PameOBP24 and PameCSP7, were expressed equally in antennae of both sexes and highly expressed amongst the OBPs and CSPs. These genes were expressed in Escherichia coli and the resultant proteins were purified. The binding affinities of 74 common odorant compounds were tested with recombinant PameOBP24 and PameCSP7. Both proteins bound a variety of ligands. Our findings provide a foundation for future research into the chemosensory mechanisms of P. americana and help in identifying potential target genes for managing this pest.

“…Periplanone-A (PA) and periplanone-B (PB) have been isolated as major sex-pheromone components [14]. They have similar chemical compositions [14] and both can qualitatively elicit the same courtship behavior in male cockroaches [13,21]. Pheromonal components are processed by distinct PA-sensitive and PB-sensitive neurons housed in the same morphologic type of sensilla (type single-walled B), which are especially abundant on the antennae of the adult male [17,19].…”

In many insect species, sex pheromone is processed by specific, enlarged glomeruli in the antennal lobes of males. In the male American cockroach, two closely located glomeruli (A and B) are responsible for processing the major pheromone components (periplanone-A and -B, respectively), and these collectively form the macroglomerular complex. Afferents originating from the dorsal and ventral surfaces of the antenna tend to project to the anterior and posterior regions of the macroglomerular complex via the dorsal and ventral antennal nerves, respectively. This topographic segregation of afferents is seen only in the macroglomerular complex, and not in other glomeruli that process normal environmental odors. Using differential, anterograde dye injection into the two antennal sensory nerves, we show that the macroglomerular complex is not formed by fusion of several glomeruli, as suggested in previous studies. but that the precursors of the A- and B-glomeruli already exist in the first larval instar. The volume of afferents in the macroglomerular complex precursor increases nearly exponentially with molting times. 430-fold from the first instar to the adult. The A- and B-glomeruli both undergo continuous growth during postembryonic development, but peak growth rates occur in different larval stages. The growth rate of the B-glomerulus peaked in the mid-developmental stage then declined, while growth of A-glomerulus was maintained at low level in early- to mid-developmental stages but increased greatly in later stages. These results suggest perception of sex pheromone occurs in early instars, and that PA and PB have distinct roles in different developmental stages
