Sensory neurons that respond to sex and aggregation pheromones in the nymphal cockroach

Abstract: in the common pest cockroach, Periplaneta americana, behavioural responses to the sex and aggregation pheromones change in an age-dependent manner. nymphs are attracted by the aggregation pheromone periplanolide-e (pLD-e) but not by the sex pheromone periplanone-B (pB) in faeces. Adults display prominent behaviours to PB but not to PLD-E. Despite the significant behavioural differences depending on postembryonic developmental stages, peripheral codings of the sex and aggregation pheromones have not been studie… Show more

“…Single sw- A sensilla had two Pame ORco-positive OSNs ( Figures 2 A and 2E). Consistent with the previous studies, OSNs in sw -A sensilla in the Control group were broadly tuned to alcohols and terpenes ( Figure 5 A; Sass, 1983 ; Fujimura et al., 1991 ; Tateishi et al., 2020 ). In the Control group, the response spectra to tested odors varied among different sw -A sensilla, suggesting that various ORxs are expressed in OSNs ( Figure 5 A).…”

“…Sex pheromones in the cockroach elicit the sexual behavior in adult males but not nymphs ( Tobin et al., 1981 ). However, nymphs also have both peripheral and central neurons to process sex pheromones ( Schaller-Selzer, 1984 ; Nishino et al., 2009 ; Tateishi et al., 2020 ). In nymphal cockroaches, PB-SNs are housed in sw -A sensilla ( Tateishi et al., 2020 ), and at final molt, the sex pheromone-responsive sw -A sensilla elongate and transform into sw- B sensilla ( Schaller, 1978 ; Watanabe et al., 2018a ).…”

“…Pheromone is defined as chemical substance secreted to the outside of an individual and detected by conspecifics triggering them to conduct stereotyped behaviour and/or have developmental changes (Karlson & Lüscher, 1959). Pheromones are essential factors in animal communication and trigger physiological change in a wide range of behavioural and ecological contexts in nature (Baracchi et al, 2017; Chalissery et al, 2019; Hostachy et al, 2019; Okosun et al, 2019; Tateishi et al, 2020). Pheromones play important roles as communication means for diverse taxonomic groups from yeast and insects to mammals (Fields, 1990).…”
