In Argentina, 10 genera and 33 species of Stenopodainae (Hemiptera: Reduviidae) have been recorded. Diagnoses of the genera, subgenera and species are given, and an illustrated key to genera is provided. Six species are new records for Argentina and an additional seven species represent new records for provinces. ...[more]

Project description:Data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. During an investigation of psyllid fauna in Serbia, natural enemies were investigated, too. True bugs were the most numerous among them. From 28 psyllid species, 21 species of true bugs from families Anthocoridae and Miridae were reared. Seven species of Anthocoridae were identified: Anthocoris amplicollis (Horváth, 1839), Anthocoris confusus Reuter, 1884, Anthocoris nemoralis (Fabricius, 1794), Anthocoris nemorum (Linnaeus, 1761), Orius majusculus Reuter, 1884, Orius minutus (Linnaeus, 1758) and Orius niger Wolff, 1811. The following 14 species of Miridae were identified: Atractotomus mali Meyer-Dür, 1843, Campylomma verbasci (Meyer-Dür, 1843), Deraeocoris flavilinea (A. Costa, 1862), Deraeocoris ruber (Linnaeus, 1758), Deraeocoris lutescens (Schilling, 1836), Heterocordylus genistae (Scopoli, 1763), Hypseloecus visci (Puton, 1888), Malacocoris chlorizans Panzer, 1794, Miris striatus (Linnaeus, 1758), Orthotylus marginalis Reuter, 1884, Psallus assimilis Stichel, 1956, Psallus quercus Kirschbaum, 1856, Psallus flavellus Stichel, 1933 and Pseudoloxops coccinea (Meyer-Dür, 1843). The aim of the research was to provide list of true bugs recorded as predators of psyllids in order to preserve their diversity and significance, especially on cultivated plants.

Project description:The genus Hemitrochostoma Bergroth, 1913 (Hemiptera, Heteroptera, Plataspidae) is redescribed and reviewed. Two species are recognized: the type species Hemitrochostomaaltilabris Bergroth, 1913 (Malaysia: Sarawak), and Hemitrochostomarutabulum sp. n. (Malaysia: Perak). The following new subjective synonymies are proposed: Hemitrochostoma Bergroth, 1913 = Inflatilabrum Tomokuni, 2012, syn. n.; Hemitrochostomaaltilabris Bergroth, 1913 = Inflatilabrumlambirense Tomokuni, 2012, syn. n.

Project description:Pentatomoidea is the largest superfamily of Pentatomomorpha; however, the phylogenetic relationships among pentatomoid families have been debated for a long time. In the present study, we gathered the mitogenomes of 55 species from eight common families (Acanthosomatidae, Cydnidae, Dinidoridae, Scutelleridae, Tessaratomidae, Plataspidae, Urostylididae and Pentatomidae), including 20 newly sequenced mitogenomes, and conducted comparative mitogenomic studies with an emphasis on the structures of non-coding regions. Heterogeneity in the base composition, and contrasting evolutionary rates were encountered among the mitogenomes in Pentatomoidea, especially in Urostylididae, which may lead to unstable phylogenetic topologies. When the family Urostylididae is excluded in taxa sampling or the third codon positions of protein coding genes are removed, phylogenetic analyses under site-homogenous models could provide more stable tree topologies. However, the relationships between families remained the same in all PhyloBayes analyses under the site-heterogeneous mixture model CAT + GTR with different datasets and were recovered as (Cydnidae + (((Tessaratomidae + Dinidoridae) + (Plataspidae + Scutelleridae)) + ((Acanthosomatidae + Urostylididae) + Pentatomidae)))). Our study showed that data optimizing strategies after heterogeneity assessments based on denser sampling and the use of site-heterogeneous mixture models are essential for further analysis of the phylogenetic relationships of Pentatomoidea.

Project description:Eight genera and 13 species of the tribe Acanthocerini are recorded in Argentina, i.e., Athaumastus haematicus (Stål), Athaumastus macer Brailovsky, Athaumastus subcarinatus (Stål), Athaumastus subterlineatus Bergroth, Beutelspacoris sanchezi Brailovsky, Beutelspacoris dilatata Casini, Camptischium clavipes (Fabricius), Crinocerus sanctus (Fabricius), Dersagrena flaviventris (Berg), Dersagrena lacerdae (Signoret), Dersagrena subfoveolata (Berg), Thlastocoris hernandezi Brailovsky and Zoreva dentipes Fabricius. Redescriptions are given for Athaumastus haematicus, Athaumastus subcarinatus and Dersagrena flaviventris with photographs of male and female genitalia of Dersagrena subfoveolata. Zoreva recorded from Argentina the first time. New locality records are given for Buenos Aires, Chaco, Formosa, Misiones, and Tucumán.

Project description:The karyotype and male meiosis, with a particular focus on the presence or absence of chiasmata between the homologs, were studied in the water boatman species Cymatia rogenhoferi (Fieber) and Cymatia coleoptrata (Fabricius) (Corixidae, Cymatiainae). It is shown that the species have 2n = 33 (28A+2m+X1X2Y) and 2n = 24 (20A+2m+XY) respectively, post-reduction of sex chromosomes, and achiasmate meiosis of an alignment type in males. Cytogenetic and some morphological diagnostic characters separating Cymatia Flor from the rest of Corixidae are discussed.

Project description:The minute pirate bugs, Orius insidiosus (Say) and Orius pumilio (Champion) (Hemiptera: Heteroptera: Anthocoridae), are closely related species known to be sympatric in north Florida. Here, male and female genitalia, DNA sequences, and the effects of within- and between-species pairings on egg production and egg development were examined to develop a better understanding of the relationship between these two species. Interspecific matings between the two species did not result in viable progeny. Although there were gross similarities in the morphology of the male parameres (external genitalia) between the two species, the cone in O. pumilio was much broader with a greater spiral twist and the flagellum was longer than in O. insidiosus. Correspondingly, there were differences in the morphology of the copulatory tubes of the females of the two species. In O. insidiosus, the organ was somewhat longer than in O. pumilio and oriented parallel to the abdominal midline, while the copulatory tube in O. pumilio tilted slightly towards the midline. Additionally, the copulatory tube for O. pumilio included a sclerotized basal mound that was not present in O. insidiosus. These morphological differences suggest that successful copulation between these species could be difficult. In contrast to conspecific matings, interspecific matings resulted in few or no eggs laid over a period of two weeks and no viable progeny. Comparison of the 18S ribosomal gene ITS-1 sequences between the two species demonstrated only 91% homology. When yolk protein contents were examined to determine whether reproductive physiology had shifted to full egg production, interspecifically mated females contained amounts of yolk protein comparable to that in fed, but unmated females; this was less than 10% of the yolk protein previously found in fed and conspecifically mated females. These findings together confirm that O. insidiosus and O. pumilio are indeed two separate species.

Project description:The kissing bug Triatoma rubida (Uhler, 1894) is found in southwestern United States and parts of Mexico where it is found infected with Trypanosoma cruzi, invades human dwellings and causes allergies from their bites. Although the protein salivary composition of several triatomine species is known, not a single salivary protein sequence is known from T. rubida. Furthermore, the salivary diversity of related hematophagous arthropods is very large probably because of the immune pressure from their hosts. Here we report the sialotranscriptome analysis of T. rubida based on the assembly of 1,820 high-quality expressed sequence tags, 51% of which code for putative secreted peptides, including lipocalins, members of the antigen five family, apyrase, hemolysin, and trialysin families. Interestingly, T. rubida lipocalins are at best 40% identical in primary sequence to those of T. protracta, a kissing bug that overlaps its range with T. rubida, indicating the diversity of the salivary lipocalins among species of the same hematophagous genus. We additionally found several expressed sequence tags coding for proteins of clear Trypanosoma spp. origin. This work contributes to the future development of markers of human and pet exposure to T. rubida and to the possible development of desensitization therapies. Supp. Data 1 and 2 (online only) of the transcriptome and deducted protein sequences can be obtained from http://exon.niaid.nih.gov/transcriptome/Trubida/Triru-S1-web.xlsx and http://exon.niaid.nih.gov/transcriptome/Trubida/Triru-S2-web.xlsx.
