“…Furthermore, JH also appears to be involved in regulating pheromone production, such as the cuticular hydrocarbon (CHC) profiles of queens and workers (Robinson and Vargo, 1997;Oliveira et al, 2017). CHCs provide nestmates with important information on an individual's caste, reproductive status and functional role in the colony (Singer and Espelie, 1992;Dani et al, 2001;Dapporto et al, 2004;Izzo et al, 2010;Ferreira-Caliman et al, 2010;Oi et al, 2015a;Kather and Martin, 2015;Valadares and Nascimento, 2016;Santos et al, 2018;reviewed in Antonialli-Junior et al, 2021). In primitively eusocial wasps, the CHC profiles of workers are linked to both JH titer and the individual's behavioral role (Sledge et al, 2004;Tibbetts and Izzo, 2009;Izzo et al, 2010).…”
