ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY 2024; 115:e22094. [PMID: 38409857 DOI: 10.1002/arch.22094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 01/31/2024] [Accepted: 02/11/2024] [Indexed: 02/28/2024]
Abstract
The predatory stink bug Arma custos has been selected as an effective biological control agent and has been successfully massly bred and released into fields for the control of a diverse insect pests. As a zoophytophagous generalist, A. custos relies on a complex neuropeptide signaling system to prey on distinct food and adapt to different environments. However, information about neuropeptide signaling genes in A. custos has not been reported to date. In the present study, a total of 57 neuropeptide precursor transcripts and 41 potential neuropeptide G protein-coupled receptor (GPCR) transcripts were found mainly using our sequenced transcriptome data. Furthermore, a number of neuropeptides and their GPCR receptors that were enriched in guts and salivary glands of A. custos were identified, which might play critical roles in feeding and digestion. Our study provides basic information for an in-depth understanding of biological and ecological characteristics of the predatory bug and would aid in the development of better pest management strategies based on the effective utilization and protection of beneficial natural enemies.

Front Physiol 2023; 14:1270751. [PMID: 37841314 PMCID: PMC10570428 DOI: 10.3389/fphys.2023.1270751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 09/19/2023] [Indexed: 10/17/2023] Open
Abstract
Predatory stink bugs derive from phytophagous stink bugs and evolved enhanced predation skills. Neuropeptides are a diverse class of ancient signaling molecules that regulate physiological processes and behavior in animals, including stink bugs. Neuropeptide evolution might be important for the development of predation because neuropeptides can be converted to venoms that impact prey. However, information on neuropeptide signaling genes in predatory stink bugs is lacking. In the present study, neuropeptide signaling genes of Picromerus lewisi, an important predatory stink bug and an effective biological agent, were comprehensively identified by transcriptome analysis, with a total of 59 neuropeptide precursor genes and 58 potential neuropeptide receptor genes found. In addition, several neuropeptides and their receptors enriched in salivary glands of P. lewisi were identified. The present study and subsequent functional research contribute to an in-depth understanding of the biology and behavior of the predatory bugs and can provide basic information for the development of better pest management strategies, possibly including neuropeptide receptors as insecticide targets and salivary gland derived venom toxins as novel killing moleculars.

FRONTIERS IN INSECT SCIENCE 2023; 3:1197945. [PMID: 38469499 PMCID: PMC10926455 DOI: 10.3389/finsc.2023.1197945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 07/19/2023] [Indexed: 03/13/2024]
Abstract
G protein-coupled receptors (GPCRs) control numerous physiological processes in insects, including reproduction. While many GPCRs have known ligands, orphan GPCRs do not have identified ligands in which they bind. Advances in genomic sequencing and phylogenetics provide the ability to compare orphan receptor protein sequences to sequences of characterized GPCRs, and thus gain a better understanding of the potential functions of orphan GPCRs. Our study sought to investigate the functions of two orphan GPCRs, AAEL003647 and AAEL019988, in the yellow fever mosquito, Aedes aegypti. From our phylogenetic investigation, we found that AAEL003647 is orthologous to the SIFamide-2/SMYamide receptor. We also found that AAEL019988 is orthologous to the Trapped in endoderm (Tre1) receptor of Drosophila melanogaster. Next, we conducted a tissue-specific expression analysis and found that both receptors had highest expression in the ovaries, suggesting they may be important for reproduction. We then used RNA interference (RNAi) to knock down both genes and found a significant reduction in the number of eggs laid per individual female mosquito, suggesting both receptors are important for Ae. aegypti reproduction.

INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2023:103963.

Abstract
Salivary glands are vital to tick feeding success and also play a crucial role in tick-borne pathogen transmission. In previous studies of Ixodes scapularis salivary glands, we demonstrated that saliva-producing type II and III acini are innervated by neuropeptidergic axons which release different classes of neuropeptides via their terminals (Šimo et al., 2009b, 2013). Among these, the neuropeptide SIFamide-along with its cognate receptor-were postulated to control the basally located acinar valve via basal epithelial and myoepithelial cells (Vancová et al., 2019). Here, we functionally characterized a second SIFamide receptor (SIFa_R2) from the I. scapularis genome and proved that it senses a low nanomolar level of its corresponding ligand. Insect SIFamide paralogs, SMYamides, also activated the receptor but less effectively compared to SIFamide. Bioinformatic and molecular dynamic analyses suggested that I. scapularis SIFamide receptors are class A GPCRs where the peptide amidated carboxy-terminus is oriented within the receptor binding cavity. The receptor was found to be expressed in Ixodes ricinus salivary glands, synganglia, midguts, trachea, and ovaries, but not in Malpighian tubules. Investigation of the temporal expression patterns suggests that the receptor transcript is highly expressed in unfed I. ricinus female salivary glands and then decreases during feeding. In synganglia, a significant transcript increase was detected in replete ticks. In salivary gland acini, an antibody targeting the second SIFamide receptor recognized basal epithelial cells, myoepithelial cells, and basal granular cells in close proximity to the SIFamide-releasing axon terminals. Immunoreactivity was also detected in specific neurons distributed throughout various I. ricinus synganglion locations. The current findings, alongside previous reports from our group, indicate that the neuropeptide SIFamide acts via two different receptors that regulate distinct or common cell types in the basal region of type II and III acini in I. ricinus salivary glands. The current study investigates the peptidergic regulation of the I. ricinus salivary gland in detail, emphasizing the complexity of this system.

Identification and characterization of the SIFamide receptor in the hemimetabolous Chagas disease vector, Rhodnius prolixus Stål, 1859, (Hemiptera, Reduviidae, Triatominae). Peptides 2021; 143:170600. [PMID: 34175354 DOI: 10.1016/j.peptides.2021.170600] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 06/18/2021] [Accepted: 06/22/2021] [Indexed: 12/19/2022]
Abstract
Within arthropods, the SIFamide family of neuropeptides appears to be involved in the modulation of a range of physiological and behavioral events. In Rhodnius prolixus, we have previously shown the presence of SIFamidergic-like processes in neurohemal release sites and provided evidence for a role for Rhopr-SIFa in modulating heartbeat frequency and feeding behaviors. Here, the R. prolixus SIFamide receptor (RhoprSIFR) has been identified, cloned, and sequenced. Sequence analyses show high similarity and identity between the RhoprSIFR and other cloned SIFamide receptors. Quantitative PCR shows that the RhoprSIFR transcript is found in a variety of tissues, including those involved in feeding and reproduction. In unfed insects, high transcript expression is observed in the central nervous system and midgut, suggesting a role of Rhopr-SIFa in various processes related to feeding and digestion. Expression of the RhoprSIFR transcript changes between unfed, 24 h post-fed, and 7 d post-fed conditions. Expression of the RhoprSIFR transcript significantly increases in the anterior midgut and posterior midgut 7 d post-feeding and knockdown of the RhoprSIFR transcript significantly reduces the size of blood meal consumed. This data suggests a possible role for Rhopr-SIFa in regulating long-term post-feeding osmotic balance and digestion of the blood meal. Lastly, transcript expression of Rhopr-SIFa and RhoprSIFR also varies temporally in relation to the reproductive stage, suggesting an involvement of this signaling pathway in reproductive activities. Identification of the RhoprSIFR and its expression profile now provide tools for a more detailed understanding into the precise coordination of feeding and other physiological processes in R. prolixus.
