Background: Rhodnius prolixus has become a model for revealing the molecular bases of insect sensory biology due to the publication of its genome and its well-characterized behavioural repertoire. Gene expression modulation underlies behaviour-triggering processes at peripheral and central levels. Still, the regulation of sensory-related gene transcription in sensory organs is poorly understood. Here we study the genetic bases of plasticity in antennal sensory function, using R. prolixus as an insect model. Results: Antennal expression of neuromodulatory genes such as those coding for neuropeptides, neurohormones and their receptors was characterized in fifth instar larvae and female and male adults by means of RNA-Sequencing (RNA-Seq). New nuclear receptor and takeout gene sequences were identified for this species, as well as those of enzymes involved in the biosynthesis and processing of neuropeptides and biogenic amines. Conclusions: We report a broad repertoire of neuromodulatory and neuroendocrine-related genes expressed in the antennae of R. prolixus and suggest that they may serve as the local basis for modulation of sensory neuron physiology. Diverse neuropeptide precursor genes showed consistent expression in the antennae of all stages studied. Future studies should characterize the role of these modulatory components acting over antennal sensory processes to assess the relative contribution of peripheral and central regulatory systems on the plastic expression of insect behaviour.

11Rhodnius prolixus has become a model for revealing the molecular bases of insect sensory biology due to 12 the publication of its genome, its well characterized behavioural repertoire and the advent of NGS 13 technologies. Gene expression modulation underlies behaviour-triggering processes at peripheral and 14 central levels. Still, the regulation of sensory-related gene transcription in sensory organs is poorly 15 understood. Here we study the genetic bases of plasticity in antennal sensory function, using R. prolixus as 16 an insect model. Antennal expression of neuromodulatory genes such as those coding for neuropeptides, 17 neurohormones and their receptors was characterized by means of RNA-Seq. New nuclear receptor and 18 takeout gene sequences were identified for this species, as well as those of enzymes involved in the 19 biosynthesis and processing of neuropeptides and biogenic amines. We report a broad repertoire of 20 neuromodulatory and endocrine genes expressed in antennae and suggest that they modulate sensory 21 neuron function locally. Diverse neuropeptide-coding genes showed consistent expression in the antennae 22 of all stages studied. Future studies should characterize the contribution of these modulatory components 23 acting over antennal sensory processes to assess the relative contribution of peripheral and central 24 regulatory systems on the plastic expression of insect behaviour.25

“…OA does not exclusively modulate muscle activity, but also sensory neurons of external tissues like the antennae, halteres and wings. OA has also been shown to increase the spontaneous activity of olfactory receptor neurons (ORN) 70 , 71 . The modulation of ORNs allows OA to modulate the innate response to attractive stimuli like fruit odors or pheromones 72 , 73 .…”

The modulation of an animal’s behavior through external sensory stimuli, previous experience and its internal state is crucial to survive in a constantly changing environment. In most insects, octopamine (OA) and its precursor tyramine (TA) modulate a variety of physiological processes and behaviors by shifting the organism from a relaxed or dormant condition to a responsive, excited and alerted state. Even though OA/TA neurons of the central brain are described on single cell level in Drosophila melanogaster, the periphery was largely omitted from anatomical studies. Given that OA/TA is involved in behaviors like feeding, flying and locomotion, which highly depend on a variety of peripheral organs, it is necessary to study the peripheral connections of these neurons to get a complete picture of the OA/TA circuitry. We here describe the anatomy of this aminergic system in relation to peripheral tissues of the entire fly. OA/TA neurons arborize onto skeletal muscles all over the body and innervate reproductive organs, the heart, the corpora allata, and sensory organs in the antennae, legs, wings and halteres underlining their relevance in modulating complex behaviors.
