  • a new species of the afrotropical braconine hymenoptera Braconidae parasitoid wasp genus doggerella with remarkable ovipositor sheaths
    Proceedings of the Entomological Society of Washington, 2020
    Co-Authors: Donald L J Quicke, Robert S Copeland, Buntika A Butcher
    Abstract:

    Doggerella knobkerrie Quicke, new species (Hymenoptera, Braconidae, Braconinae), from Kenya is described and illustrated photographically. The description is justified because of the remarkably developed, club-like, ovipositor sheaths, not known elsewhere in the Ichneumonoidea.

  • using taxonomic revision data to estimate the geographic and taxonomic distribution of undescribed species richness in the Braconidae hymenoptera ichneumonoidea
    Insect Conservation and Diversity, 2009
    Co-Authors: Owen R Jones, Donald L J Quicke, Andy Purvis, Eligiusz Baumgart
    Abstract:

    Abstract.  1. Knowledge of global diversity patterns is important for research into the factors that shape them, and for systematic conservation planning. However, most species inventories are incomplete and biased towards conspicuous, charismatic, geographically widespread, and temperate species. These biases hamper attempts to gain a clear view of underlying diversity patterns, and compromise conservation plans that are based upon what is known. 2. Here we investigate this problem using two methods to estimate species diversity in the parasitic wasp family Braconidae. The first quantifies the effect of taxonomic revisions on species numbers within genera to estimate the present level of underdescription. The second additionally considers the numbers of specimens referred to in descriptions and revisions. 3. Modelling underdescription as a function of region and body size shows that research carried out thus far displays significant geographical and taxonomic biases. 4. Correcting for these biases affects the distribution of inferred undiscovered diversity among braconid subfamilies and among regions, as well as the total diversity estimates for the family. 5. The geographic distribution of levels of underdescription also has implications for latitudinal diversity gradients. Weak or non-existent gradients in some taxa may be caused simply by differences in the number of undescribed species between tropical and temperate regions. 6. Such analyses can enlighten researchers as to where, taxonomically and geographically, research should be directed to economically improve species richness estimates. In the case of braconid wasps the greatest gains are to be made in Africa and southern America, and for the Braconinae and Microgastrinae.

  • a phylogenetic reconstruction of the ichneumonoidea hymenoptera based on the d2 variable region of 28s ribosomal rna
    Systematic Entomology, 1998
    Co-Authors: Robert Belshaw, Elisabeth A Herniou, Mike G Fitton, Donald L J Quicke, Carmen Gimeno
    Abstract:

    The D2 variable region of 28S rRNA was sequenced in a wide range of Ichneumonoidea to provide the first comprehensive phylogenetic reconstruction of this superfamily. The two constituent families (Braconidae and Ichneumonidae) were each found to contain a single well-supported clade dominated by the more plesiomorphic life history strategies (idiobiosis, ectoparasitism and attacking endoephytic hosts). In the Braconidae this clade corresponds to the morphologically-defined group called the cyclostomes. In the Ichneumonidae the clade unites for the first time the pimpliformes (sensu Wahl) with most of the phygadeuontoid subfamilies and several small taxa including Adelognathus and Euceros. Relationships among the remaining, more biologically-derived, subfamilies were less well resolved, but included among the Braconidae a well-supported microgastroid clade and strong evidence for a sister group relationship between the Agathidinae and Sigalphinae.

  • phylogenetic relationships among the Braconidae hymenoptera ichneumonoidea inferred from partial 16s rdna 28s rdna d2 18s rdna gene sequences and morphological characters
    Molecular Phylogenetics and Evolution, 2005
    Co-Authors: Xue-xin Chen, C Van Achterberg
    Abstract:

    Abstract Phylogenetic relationships among the Braconidae were examined using homologous 16S rDNA, 28S rDNA D2 region, and 18S rDNA gene sequences and morphological data using both PAUP* 4.0 and MRBAYES 3.0B4 from 88 in-group taxa representing 35 subfamilies. The monophyletic nature of almost all subfamilies, of which multiple representatives are present in this study, is well-supported except for two subfamilies, Cenocoelinae and Neoneurinae that should probably be treated as tribal rank taxa in the subfamily Euphorinae. The topology of the trees generated in the present study supported the existence of three large generally accepted lineage or groupings of subfamilies: two main entirely endoparasitic lineages of this family, referred to as the “helconoid complex” and the “microgastroid complex,” and the third “the cyclostome.” The Aphidiinae was recovered as a member of the non-cyclostomes, probably a sister group of Euphorinae or Euphorinae-complex. The basal position of the microgastroid complex among the non-cyclostomes has been found in all our analyses. The cyclostomes were resolved as a monophyletic group in all analyses if two putatively misplaced groups (Mesostoa and Aspilodemon) were excluded from them. Certain well-supported relationships evident in this family from the previous analyses were recovered, such as a sister-group relationships of Alysiinae + Opiinae, of Braconinae + Doryctinae, and a close relationship between Macrocentrinae, Xiphozelinae, Homolobinae, and Charmontinae. The relationships of “Ichneutinae + ((Adeliinae + Cheloninae) + (Miracinae + (Cardiochilinae + Microgastrinae)))” was confirmed within the microgastroid complex. The position of Acampsohelconinae, Blacinae, and Trachypetinae is problematic.

  • Multiple Lines of Evidence from Mitochondrial Genomes Resolve Phylogenetic Relationships of Parasitic Wasps in Braconidae
    Genome biology and evolution, 2016
    Co-Authors: Wei Shujun, Michael J Sharkey, Min Shi, Pu Tang, Xue-xin Chen
    Abstract:

    The rapid increase in the number of mitochondrial genomes in public databases provides opportunities for insect phylogenetic studies; but it also provides challenges because of gene rearrangements and variable substitution rates among both lineages and sites. Typically, phylogenetic studies use mitochondrial sequence data but exclude other features of the mitochondrial genome from analyses. Here, we undertook large-scale sequencing of mitochondrial genomes from a worldwide collection of specimens belonging to Braconidae, one of the largest families of Metazoa. The strand-asymmetry of base composition in the mitochondrial genomes of braconids is reversed, providing evidence for monophyly of the Braconidae. We have reconstructed a backbone phylogeny of the major lineages of Braconidae from gene order of the mitochondrial genomes. Standard phylogenetic analyses of DNA sequences provided strong support for both Cyclostomes and Noncyclostomes. Four subfamily complexes, that is, helconoid, euphoroid, sigalphoid, and microgastroid, within the Noncyclostomes were reconstructed robustly, the first three of which formed a monophyletic group sister to the last one. Aphidiinae was recovered as a lineage sister to other groups of Cyclostomes, while the Ichneutinae was recovered as paraphyletic. Separate analyses of the subdivided groups showed congruent relationships, employing different matrices and methods, for the internal nodes of the Cyclostomes and the microgastroid complex of subfamilies. This research, using multiple lines of evidence from mitochondrial genomes, illustrates multiple uses of mitochondrial genomes for phylogenetic inference in Braconidae.

  • Comparative mitogenomics of Braconidae (Insecta: Hymenoptera) and the phylogenetic utility of mitochondrial genomes with special reference to Holometabolous insects
    BMC genomics, 2010
    Co-Authors: Wei Shujun, Michael J Sharkey, Min Shi, Cornelis Van Achterberg, Xue-xin Chen
    Abstract:

    Background Animal mitochondrial genomes are potential models for molecular evolution and markers for phylogenetic and population studies. Previous research has shown interesting features in hymenopteran mitochondrial genomes. Here, we conducted a comparative study of mitochondrial genomes of the family Braconidae, one of the largest families of Hymenoptera, and assessed the utility of mitochondrial genomic data for phylogenetic inference at three different hierarchical levels, i.e., Braconidae, Hymenoptera, and Holometabola.

  • phylogenetic relationships among the Braconidae hymenoptera ichneumonoidea a reassessment of shi et al 2005
    Molecular Phylogenetics and Evolution, 2007
    Co-Authors: Kevin M Pitz, Andrew C Boring, Katja C Seltmann, Barbara J Sharanowski, Ashley P G Dowling, Michael J Sharkey
    Abstract:

    Phylogenetic relationships among the Braconidae have been a source of contention, debate, and uncertainty for many years. This uncertainty has been evident in the conXicting relationships and lack of resolution obtained from various morphological (van Achterberg, 1984; Quicke and van Achterberg, 1990; Wharton et al., 1992) and molecular datasets (Dowton et al., 1998; Belshaw et al., 1998; Dowton et al., 2002). Recently, Shi et al. (2005) analyzed a large morphological and multi-gene dataset. The morphological components of their dataset were compiled from the previously published works of Quicke and van Achterberg (1990) and modiWed by van Achterberg and Quicke (1992) and Dowton et al. (2002). Their molecular dataset was compiled from published sequences from GenBank (http://www.ncbi.nlm.nih.gov/) and seven new sequences provided by the authors. The combined dataset was the largest employed in a systematic analysis of the Braconidae. However, the analysis performed by Shi et al. (2005) contained several methodological and conceptual errors. The purpose of the present paper is to address these errors, attempt to reproduce the original dataset, and oVer a re-analysis of the molecular dataset in hopes to further the present knowledge of relationships among the Braconidae.
