“…Furthermore, they could serve as a reference for further studies as they constitute the first report on cuticular non-volatile compounds in a treehopper species and, in fact, in the whole order Hemiptera, in the context of kin recognition. The only reports of cuticular semiochemicals in the Hemiptera have focused on chemotaxonomy, aggregation and sexual behaviours (Fucarino et al, 2004;Cocchiararo-Bastias et al, 2011;Calderón-Fernández & Juárez, 2013). Our results also suggest that a rocking behaviour by nymphs could be another potential mechanism used as a signal for kin recognition in this treehopper species.…”

“…The presence or absence of a compound in the chromatogram was determined following Flores-Prado et al (2008) and Aguilera-Olivares et al (2016), by identifying compounds based on comparisons of their retention index and mass spectrum with those in the NIST14 database, with authentic standards (when available) and, eventually, with data from the literature (Flores-Prado et al, 2008;Cocchiararo-Bastias et al, 2011;Calderón-Fernández & Juárez, 2013;Beran et al, 2014;El-Sayed, 2014;Aguilera-Olivares et al, 2016). Then, 4 l of the re-dissolved extracts were injected in a Shimadzu model GCMS-QP 2010 Ultra gas chromatograph (Shimadzu, Kyoto, Japan) equipped with an Rtx-5MS Crossbond 5% diphenyl 95% dimethyl polysiloxane (Restek, Bellefonte, Philadelphia) capillary gas chromatograph (GC) column (length 30 m, internal diameter 0.25 mm, film thickness 0.25 m) and used in the splitless mode.…”

“…Additionally, cuticular compounds that could be acting as pheromones have never been studied or described in treehoppers, at least in a social context (Silveira et al, 2010). The only reports of cuticular semiochemicals in the Hemiptera have focused on chemotaxonomy, aggregation and sexual behaviours (Fucarino et al, 2004;Cocchiararo-Bastias et al, 2011;Calderón-Fernández & Juárez, 2013). Our results indicate that nymphal cuticular non-volatile compounds differed qualitatively and quantitatively between and within nymphal cohorts, and that these differences were higher between (non-kin) than within (kin) cohorts suggesting that cuticular compounds are indeed good candidates for kin recognition.…”

“…Retention indexes were calculated on the basis of chromatograms obtained from the periodic injection of a standard alkane mixture. The presence or absence of a compound in the chromatogram was determined following Flores-Prado et al (2008) and Aguilera-Olivares et al (2016), by identifying compounds based on comparisons of their retention index and mass spectrum with those in the NIST14 database, with authentic standards (when available) and, eventually, with data from the literature (Flores-Prado et al, 2008;Cocchiararo-Bastias et al, 2011;Calderón-Fernández & Juárez, 2013;Beran et al, 2014;El-Sayed, 2014;Aguilera-Olivares et al, 2016). An identification was proposed if the retention index did not differ by more than five units and the similarity index of the mass spectrum was over 85% compared with the database or the literature.…”

1. Insects exhibiting parental care usually can discriminate between kin and non-kin individuals, allowing parents to avoid investment in foreign offspring.2. This study investigated the occurrence of kin recognition in the sap-feeding insect Alchisme grossa Fairmaire (Membracidae) through bioassays assessing median female distance to nymphs and degree of nymphal aggregation. Each bioassay involved groups consisting of a female and a cohort of kin or non-kin nymphs (mother and non-mother treatments, respectively). Furthermore, cuticular non-volatile compounds were extracted from nymphal cohorts, analysed by gas chromatography-mass spectrometry and compared between cohorts.3. In both treatments, nymphs performed a 'rocking behaviour' which appears to be correlated with aggregation. Temporal patterns of degree of nymphal aggregation and median female-nymph distance differed between treatments, the former parameter being higher in the mother treatment and the latter being higher in the non-mother treatment.4. A total of 40 compounds were found in the extracts. The composition of cuticular non-volatile compounds differed between nymphal cohorts. 5. These results support the notion that kin recognition in A. grossa is possibly mediated by nymphal rocking behaviour and/or cuticular non-volatile compounds (i.e. visual and/or chemical cues).

“…The main function of these lipids in the insect is to restrict water loss and avoid lethal drying. It has been shown that they also participate in the absorption of chemical substances that can affect the activity of microorganisms and intervene in various chemical communication processes [33][34][35].…”

In México, biogeography data are available for species of triatomas called Trypanosoma cruzi transmitters; for example, the phyllosoma complex is distributed in several states of the south-central southeast of the country. In contrast, Northwestern Mexico species such as Triatoma rubida are considered sylvatic and in the process of domestication. The lack of research of these northern species of the country has generated an ignorance that contrasts with a growing number of alleged new cases of Chagas disease registered in health institutions in states such as Sonora. From the six species of triatomas that are potential transmitters of the trypanosoma in the state of Sonora, Triatoma rubida is the only one that has recent studies of distribution and transmission capacity. It is important then to know the degree of domesticity of the native species with the capacity of transmission of Trypanosoma cruzi and to define areas of risk. The process of adaptation of the sylvatic triatomines to the peridomestic and the domestic habitat has been understood in terms of environmental and biological variables. In this research, the profile of cuticular hydrocarbons of a peridomestic, domestic and sylvatic population of Triatoma rubida was analyzed and compared.

BACKGROUND The redbanded stink bug Piezodorus guildinii (Heteroptera: Pentatomidae) is one of the most important species affecting soybean crops in southern South America. Capillary gas chromatography coupled to mass spectrometry was used to characterize the epicuticular hydrocarbon profiles of field‐collected insects, and to identify differences in their composition between fifth‐instar nymphs and adults, males and females, and between bugs collected in insecticide‐treated and insecticide‐free soybean crops. RESULTS Straight chain saturated n‐C27 and n‐C29, and monomethyl and dimethyl chains of C31 and C33 were the most abundant compounds. A group of volatile hydrocarbons with n‐C13 and n‐C15 as the predominant compounds were also detected. The hydrocarbon pattern was different between nymphs and adults, either males or females. Heneicosene was almost exclusively detected in adult males and was the most important component to differentiate between both sexes, followed by tricosadiene. The total hydrocarbon amount was significantly higher in nymphs, males and females collected in insecticide‐treated fields compared with insects obtained from untreated fields. CONCLUSION Differences were found in the epicuticular hydrocarbon pattern among nymphs and adults, as well as sexual dimorphism in adult stink bugs. Interestingly, an alteration was also found in the hydrocarbon profile of insects collected in insecticide‐treated soybean crops and its relevance is discussed within a pest management context.
