Abstract: The desert locust Schistocerca gregaria detects odorants through olfactory sensory neurons (OSNs) that are surrounded by non-neuronal support cells (SCs). OSNs and SCs are housed in cuticle structures, named sensilla found abundantly on the antenna in all developmental stages of the hemimetabolic insect. In insects, multiple proteins expressed by OSNs and SCs are indicated to play a pivotal role in the detection of odorants. This includes insect-specific members of the CD36 family of lipid receptors and transporters called sensory neuron membrane proteins (SNMPs). While the distribution pattern of the SNMP1 and SNMP2 subtypes in OSNs and SCs across different sensilla types has been elucidated for the adult S. gregaria antenna, their localization in cells and sensilla of different developmental stages is unclear. Here, we determined the SNMP1 and SNMP2 expression topography on the antenna of the first, third and fifth instar nymphs. Through FIHC experiments we found that in all developmental stages SNMP1 is expressed in OSNs and SCs of the trichoid and basiconic sensilla while SNMP2 is restricted to the SCs of the basiconic and coeloconic sensilla thus resembling the adult arrangement. Our results demonstrate that both SNMP types have defined cell- and sensilla-specific distribution patterns established already in the first instar nymphs and retained into the adult stage. This conserved expression topography underlines the importance of SNMP1 and SNMP2 in olfactory processes throughout the development of the desert locust.
