“…Our analysis detected four SNMP sequences that belonged to SNMP1 and SNMP2 subfamilies. Although most insects have two SNMPs, there are beetle species with antennal expression of 3 ( I. typographus and D. ponderosae ), 4 ( Rhaphuma horsfieldi White, Sitophilus zeamais Motschulsky, Dendroctonus valens LeConte and Dastarcus helophoroides Fairmaire), and even 6 ( T. castaneum ) SNMPs (reported in [ 59 , 105 ]). The role of SNMP1 in pheromone detection has been demonstrated in few Diptera and Lepidoptera species [ 106 , 107 , 108 ].…”

In predatory ladybirds (Coleoptera: Coccinellidae), antennae are important for chemosensory reception used during food and mate location, and for finding a suitable oviposition habitat. Based on NextSeq 550 Illumina sequencing, we assembled the antennal transcriptome of mated Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) males and females and described the first chemosensory gene repertoire expressed in this species. We annotated candidate chemosensory sequences encoding 26 odorant receptors (including the coreceptor, Orco), 17 gustatory receptors, 27 ionotropic receptors, 31 odorant-binding proteins, 12 chemosensory proteins, and 4 sensory neuron membrane proteins. Maximum-likelihood phylogenetic analyses allowed to assign candidate H. axyridis chemosensory genes to previously described groups in each of these families. Differential expression analysis between males and females revealed low variability between sexes, possibly reflecting the known absence of relevant sexual dimorphism in the structure of the antennae and in the distribution and abundance of the sensilla. However, we revealed significant differences in expression of three chemosensory genes, namely two male-biased odorant-binding proteins and one male-biased odorant receptor, suggesting their possible involvement in pheromone detection. Our data pave the way for improving the understanding of the molecular basis of chemosensory reception in Coccinellidae.

Differential expression analysis between males and females revealed low variability between sexes, possibly reflecting the known absence of relevant sexual dimorphism in the structure of the antennae and in the distribution and abundance of the sensilla.

“…Sensory neuron membrane protein ( SNMP ) genes are the insect‐specific orthologues of the vertebrate CD36 genes (Rogers et al, 1997 ) which, among others, are involved in the uptake of long‐chain fatty acids by adipose and heart cells (Coburn et al, 2000 ; Febbraio & Silverstein, 2007 ). So far, three clusters of SNMP s orthologues have been identified: SNMP‐1 is highly conserved and has been found in a broad range of insect genomes (Forstner et al, 2008 ; Gomez‐Diaz et al, 2016 ; Gu et al, 2013 ; Jiang et al, 2016 ; Rogers et al, 1997 ; Xia et al, 2019 ). SNMP proteins located in the membranes of ORN dendrites of the pheromone‐sensitive trichoeda (Benton et al, 2007 ; Gu et al, 2013 ; Jiang et al, 2016 ) and basiconic sensilla (Benton et al, 2007 ).…”

“…Similar to SNMP‐1 , the SNMP‐2 gene is found across insects (Forstner et al, 2008 ; Gu et al, 2013 ; Jiang et al, 2016 ; Rogers et al, 1997 ; Xia et al, 2019 ) and is expressed in sensory appendices such as antennae, maxillary palps, and legs (Forstner et al, 2008 ; Gu et al, 2013 ; Jiang et al, 2016 ; Xia et al, 2019 ). In situ hybridisation in Heliothis virescens revealed that SNMP‐2 is primarily expressed in the support cells of SNs (Forstner et al, 2008 ) and in Agrotis ipsilon , SNMP‐2 proteins have been located in the sensilla lymph and in the general odourant sensitive sensilla basiconica (Gu et al, 2013 ).…”

Genetic mechanisms modulating behaviour through plastic chemosensory responses in insects

The ability to transition between different behavioural stages is a widespread phenomenon across the animal kingdom. Such behavioural adaptations are often linked to changes in the sensitivity of those neurons that sense chemical cues associated with the respective behaviours. To identify the genetic mechanisms that regulate neuronal sensitivity, and by that behaviour, typically *omics approaches, such as RNA‐ and protein‐sequencing, are applied to sensory organs of individuals displaying differences in behaviour. In this review, we discuss these genetic mechanisms and how they impact neuronal sensitivity, summarize the correlative and functional evidence for their role in regulating behaviour and discuss future directions. As such, this review can help interpret *omics data by providing a comprehensive list of already identified genes and mechanisms that impact behaviour through changes in neuronal sensitivity.
