Molecular Basis of Pheromonogenesis Regulation in Moths
Chapter 8 Molecular Basis of Pheromonogenesis Regulation in Moths J. Joe Hull and Adrien Fónagy Abstract Sexual communication among the vast majority of moths typically involves the synthesis and release of species-specifc, multicomponent blends of sex pheromones (types of insect semiochemicals) by females. These compounds are then interpreted by conspecifc males as olfactory cues regarding female reproduc- tive readiness and assist in pinpointing the spatial location of emitting females. Studies by multiple groups using different model systems have shown that most sex pheromones are synthesized de novo from acetyl-CoA by functionally specialized cells that comprise the pheromone gland. Although signifcant progress was made in identifying pheromone components and elucidating their biosynthetic pathways, it wasn’t until the advent of modern molecular approaches and the increased avail- ability of genetic resources that a more complete understanding of the molecular basis underlying pheromonogenesis was developed. Pheromonogenesis is regulated by a neuropeptide termed Pheromone Biosynthesis Activating Neuropeptide (PBAN) that acts on a G protein-coupled receptor expressed at the surface of phero- mone gland cells. Activation of the PBAN receptor (PBANR) triggers a signal trans- duction cascade that utilizes an infux of extracellular Ca2+ to drive the concerted action of multiple enzymatic steps (i.e. chain-shortening, desaturation, and fatty acyl reduction) that generate the multicomponent pheromone blends specifc to each species. In this chapter, we provide a brief overview of moth sex pheromones before expanding on the molecular mechanisms regulating pheromonogenesis, and con- clude by highlighting recent developments in the literature that disrupt/exploit this critical pathway.

Phylogenetic Relationships of Tachinid Flies in Subfamily Exoristinae Tachinidae: Diptera) Based on 28S Rdna and Elongation Factor-1A
Systematic Entomology *2002) 27,409±435 Phylogenetic relationships of tachinid flies in subfamily Exoristinae Tachinidae: Diptera) based on 28S rDNA and elongation factor-1a JOHN O. STIREMAN III Department of Ecology and Evolutionary Biology,University of Arizona,Tucson,U.S.A. Abstract. The phylogenetic relationships within the largest subfamily of Tachi- nidae,Exoristinae,were explored using nucleotide sequences of two genes *EF-1 a and 28S rDNA). A total of fifty-five and forty-three taxa were represented in the analyses for each gene,respectively,representing forty-three genera. Neighbour joining,parsimony and maximum likelihood inference methods were employed to reconstruct phylogenetic relationships in separate analyses of each gene,and parsimony was used to analyse the combined dataset. Although certain taxa were highly mobile,phylogenetic reconstructions generally supported recent clas- sification schemes based on reproductive habits and genitalia. Generally,the monophyly of Tachinidae and Exoristinae was supported. Tribes Winthemiini, Exoristini and Blondeliini were repeatedly constructed as monophyletic groups, with the former two clades often occupying a basal position among Exoristinae. Goniini and Eryciini generally clustered together as a derived clade within Exoristinae; however,they were never reconstructed as two distinct clades. These results suggest that the possession of unembryonated eggs is plesiomorphic within the subfamily and that there may have been multiple transitions between micro- type and macrotype egg forms. Introduction 1987; Williams et al.,1990; Eggleton & Belshaw,1993), and the wide variety of mechanisms by which they attack Tachinidae is generally regarded as a relatively recent, them *O'Hara,1985). These oviposition strategies include actively radiating clade of parasitic flies *Crosskey,1976). -

Infection was confirmed by tissue polymerase chain reaction and sequence analysis. Results showed that dead H. peltigera larvae contain Helicoverpa armigera nucleopolyhedrovirus. Thus, the isolate was named as HearNPV-TR. Microscopy studies indicated that occlusion bodies were 0.73 to 1.66 μm in diameter. The nucleocapsids are approximately 184 × 41 nm in size. The genome of HearNPV-TR was digested with KpnI and XhoI enzymes and calculated as 130.5 kb. Phylogenetic analysis showed that HearNPV-TR has close relation with the H. armigera SNPV-1073 China isolate. The Kimura analysis confirmed that the isolate is a variant of H. armigera NPV. Bioassays were performed using six different concentrations (1 × 310 to 1 × 8 10 occlusion bodies (OBs)/mL)on 2nd instar larvae of H. peltigera, H. armigera, Heliothis viriplaca, Heliothis nubigera. LC50 values were calculated to be 9.5 × 103, 1.9 × 104, 8.6 × 104 and 9.2 × 104 OBs/mL within 14 days, respectively. Results showed that it is a promising biocontrol agent against Heliothinae species. -

D. Kravchenko, A.-L.-L. Friedman & G. C. Müller Abstract The Lebanon and Anti-Lebanon ridges are located in the middle of a narrow “Mediterranean ecozone” corridor stretching along the Levantine coast. Both ridges are high enough to feature a complete range of altitude zones, which includes an alpine tragacanth belt (> 2000 m a.s.l.). The southernmost part of the Anti-Lebanon ridge is situated in the northernmost part of Israel. Among the 548 Israeli Noctuidae species, 106 species (21%) occur only in this small mountainous area. Among them, 17 are endemic and the populations of the remaining 89 species are at the edge of their distribution range. -
Neuroscience Needs Ethology: the Marked Example of the Moth Pheromone System
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 16 July 2020 doi:10.20944/preprints202007.0357.v1 Review Neuroscience needs ethology: the marked example of the moth pheromone system Hervé Thevenon 1 1 Affiliation: Spascia; [email protected] 2 Correspondence: [email protected] Abstract: The key premise of translational studies is that knowledge gained in one animal species can be transposed to other animals. So far translational bridges have mainly relied on genetic and physiological similarities, in experimental setups where behaviours and environment are often oversimplified. These simplifications were recently criticised for decreasing the intrinsic value of the published results. The inclusion of wild behaviour and rich environments in neuroscience experimental designs is difficult to achieve because no animal model has it all. As an example, the genetic toolkit of moths species is virtually non-existent when compared to C. elegans, rats, mice, or zebrafish, however the balance is reversed for wild behaviours. The ethological knowledge gathered about the moth was instrumental for designing natural-like auditory stimuli, that were used in association with electrophysiology in order to understand how moths use these variable sounds produced by their predators in order to trump death. Conversely, we are still stuck with understanding how male moths make sense of their complex and diffuse olfactory landscape in order to locate conspecific females up to several hundred meters away, and precisely identify a conspecific in a sympatric swarm in order to reproduce. This systemic review articulates the ethological knowledge pertaining to this unresolved problem and leverages the paradigm to gain insight into how male moths process sparse and uncertain environmental sensory information. -
Molecular Analysis of Enteroviruses
Journal of Human Virology & Retrovirology Molecular Analysis of Enteroviruses Abstract Review Article Enteroviruses (EVs) are common human pathogens which usually infect the Volume 3 Issue 2 - 2016 gastrointestinal and respiratory tracts and can spread to other organs or systems. They are characterized by high genomic plasticity, primarily due to high mutation and recombination rates. Improved molecular diagnostic methods and genetic sequence analyses are beginning to discover the complex characteristics of individual serotypes and genotypes. Understanding the tempo and pattern of molecular diversity and evolution is of great importance in the pathogenesis Centre for Infectious Diseases and Microbiology (CIDM), of EVs, information which will assist in disease prevention and control.
