The species is famous for the strong and pleasant aromatic scent of mature males in the gregarious phase. We identified this fragrance as a mixture of two main aromatic compounds, benzyl alcohol, and 2-phenylethanol. The male-specific volatiles are emitted almost exclusively from the abdomen. The release of the male volatiles is linked to sexual maturity and is influenced by the intensity of sexual competition between males. Consequently, a function of the volatiles as a gregarious mature male-emitted pheromone in the context of reproduction is obvious. No female-specific volatiles were found. Some compounds of the semivolatile fraction of the cuticular hydrocarbon (CHC) profile were also detected in the headspace of both sexes. This fraction of the CHCs of <i>S. cancellata</i> consists almost entirely of unbranched C23 to C31 alkanes. The profiles vary slightly between the sexes and differ from the reference profile of the prominent and well-studied species <i>S. gregaria</i>. Thus, semivolatile components of the CHCs may also play an important role in the short-range mate recognition system of the species.</p></div>","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"33 3-4","pages":"63 - 70"},"PeriodicalIF":1.8,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00049-023-00385-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4464791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such defense reactions in pines can be induced by the attack of herbivores. The banded pine weevil, <i>Pissodes castaneus</i> (De Geer, 1775) (Coleoptera, Curculionidae), is an important pest of <i>Pinus</i> in Brazil, where it has been an invasive species since 2001.

We analyzed how the attack by <i>P. castaneus</i> males and females affects the volatile pattern emitted by the twigs. When comparing volatiles produced by healthy plants and by female- and male-attacked <i>P. taeda</i>, qualitative and quantitative differences were detected, as the decreased production of limonene, germacrene D and (<i>E</i>)-caryophyllene and the increase of α-pinene.

One largely neglected family in this context is the Mutillidae (velvet ants), whose species are ectoparasitoids of bees and wasps. In our study, we characterized and compared the CHC profiles of five species of Mutillidae and seven host species. The CHC profile of velvet ants differed among species and included large proportions of <i>n</i>-alkanes and methyl-branched alkanes. Alkenes were much less abundant in the CHC profiles of three species of velvet ants compared with their hosts, while the other two species possess a much lower abundance of methyl-branched alkanes than their hosts. Both the number of peaks and compound diversity were generally higher in velvet ants compared with their hosts. Thus, CHC profiles of parasitoids did not show signs of mimicry when compared with their hosts. In dyadic encounters between one species of velvet ant and its host bee species, the parasitoid mainly avoided interacting, while aggression by the host was rare. Our results suggest that velvet ants did not evolve chemical mimicry, perhaps in accordance with their wide host spectrum which would limit chemical specialization. However, the reduction of alkenes in social bee-attacking species and the reduction of methyl-branched alkanes in social wasp-attacking species may favour host nest invasion, since these two CHC classes are known to be important in nestmate recognition for social bees and wasps, respectively. A larger, phylogeny-corrected comparison of Mutillidae and hosts may help clarifying the evolution of the CHC profile of these parasitoids.\u0000</p></div>","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"33 1-2","pages":"29 - 43"},"PeriodicalIF":1.8,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00049-023-00382-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4979542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We specifically compared the amount of iridomyrmecin among supercolonies in the native range and among three invasive supercolonies: the Main supercolony (the most extended worldwide), the Corsican and the Catalonian supercolonies (both with a restricted distribution in Europe). Our main result is that the variability of the iridomyrmecin is very high. Looking at mean values, we found that the amount of iridomyrmecin of the Main supercolony was the lowest while the highest corresponded to the Corsican supercolony, with the Catalonian and the native range supercolonies having intermediate values. However, variability in the values within each supercolony was similar between supercolonies. This suggests that the success of a given invasive supercolony may not be explained by higher quantities of this defensive compound.

Among these are <i>Gonyleptes curticornis</i> (Mello-Leitão, 1940) and <i>G. horridus</i> Kirby, 1819, the latter being particularly important, because it is the type species of the genus, which in turn names the subfamily Gonyleptinae. <i>Gonyleptes horridus</i> is also used in many phylogenetic analyses, be it using morphological or molecular data. The chemical study of the secretions of these two species by GC–MS and ¹H NMR showed the presence of 1-(6-isopropyl-3,4-dihydro-2H-pyran-2-yl)-methylbutanone, 1-(6-isopropyl-3,4-dihydro-2H-pyran-2-yl) isobutanone and 4-methyl-1-hepten-3-one in both species. On the other hand, 4-methyl-1-hexen-3-one was observed only in <i>G. curticornis</i>, and 7-methyl-2-octanol is exclusive of <i>G. horridus</i>. All vinyl-ketones identified have already been described for Gonyleptidae. We ran an Ancestral Character State Reconstruction (ASR) analysis under three different conditions to infer the evolution of the identified compounds (based on modified characters of a previous study) and their chemical nature (multistate character, either as alkylphenol, benzoquinone or vinyl-ketone) on a modified Gonyleptidae phylogeny. Our results corroborate previous studies that alkylphenol is the ancestral most condition, changing to benzoquinone in the ancestor of Gonyleptidae or even earlier in a grassatorean ancestor depending on the analysis. Vinyl-ketones are a synapomorphy of K92. We briefly discuss character codifications and use of weights of ASR analyses of specific compounds, which were inconclusive. 1-(6-isopropyl-3,4-dihydro-2H-pyran-2-yl) isobutanone is shared by both <i>Gonyleptes</i> species and described for the genus <i>Sodreana</i> Mello-Leitão, 1922. 1-(6-(1-methyl-propyl)3,4-dihydro-2H-pyran-2yl)2-methylbutanone and 4-methyl-1-hepten-3-one are also shared by both <i>Gonyleptes</i> species and described for <i>Moreiranula saprophila</i>.
