  • Inferring life history from ovipositor morphology in parasitoid wasps using phylogenetic regression and discriminant analysis
    Zoological Journal of the Linnean Society, 2020
    Co-Authors: Robert Belshaw, Alan Grafen, Donald L. J. Quicke
    Abstract:

    Our understanding of the critical shift in life history among insect parasitoids from ectoparasitism to endoparasitism is hindered by the fact that this particular life history trait is not known for many phylogenetically important taxa. One method of coping with this problem is to seek correlations between the ovipositor structure and this life history trait among taxa whose life history is known, and then to use this to infer the trait in species whose life history in unknown. In one group of parasitoid wasps, the Ichneumonoidea (Hymenoptera), we scored a total of 20 morphometric and morphological characters of the ovipositor for 41 species whose life histories are known – representing all the main clades in which there have been independent transitions to endoparasitism plus a broad range of the ectoparasitoid groups; we then used phylogenetic regression and discriminant analyses to infer the life history of four species whose life histories are unknown. To allow for the effect of phylogenetic non-independence in the discriminant analysis, we carried out analyses using different randomly chosen representatives of the endoparasitoid clades (phylogenetic regression controls for phylogeny). These two methods gave congruent results from which we conclude that Megalohelcon and Gnamptodon are endoparasitoids, and Aspilodemon and Allobracon are ectoparasitoids. We discuss the consequences of these inferences for our understanding of the evolution of endoparasitism in the Ichneumonoidea. © 2003 The Linnean Society of London.

  • utility of the dna barcoding gene fragment for parasitic wasp phylogeny hymenoptera Ichneumonoidea data release and new measure of taxonomic congruence
    Molecular Ecology Resources, 2012
    Co-Authors: Donald L. J. Quicke, Alex M Smith, Daniel H Janzen, Winnie Hallwachs, Jose Fernandeztriana, Nina Laurenne, Alejandro Zaldivarriveron, Mark R Shaw, Gavin R Broad
    Abstract:

    The enormous cytochrome oxidase subunit I (COI) sequence database being assembled from the various DNA barcoding projects as well as from independent phylogenetic studies constitutes an almost unprecedented amount of data for molecular systematics, in addition to its role in species identification and discovery. As part of a study of the potential of this gene fragmenttoimprove theaccuracyofphylogeneticreconstructions, andin particular, exploring theeffects ofdense taxon sampling, we have assembled a data set for the hyperdiverse, cosmopolitan parasitic wasp superfamily Ichneumonoidea, including the release of 1793 unpublished sequences. Of approximately 84 currently recognized Ichneumonoidea subfamilies, 2500 genera and 41 000 described species, barcoding 5¢-COI data were assembled for 4168 putative species-level terminals (many undescribed), representing 671 genera and all but ten of the currently recognized subfamilies. After the removal of identical and near-identical sequences, the 4174 initial sequences were reduced to 3278. We show that when subjected to phylogenetic analysis using both maximum likelihood and parsimony, there is a broad correlation between taxonomic congruence and number of included sequences. We additionally present a new measure of taxonomic congruence based upon the Simpson diversity index, the Simpson dominance index, which gives greater weight to morphologically recognized taxonomic groups (subfamilies) recovered with most representatives in one or a few contiguous groups or subclusters.

  • assessing the reliability of biodiversity databases identifying evenly inventoried island parasitoid faunas hymenoptera Ichneumonoidea worldwide
    Insect Conservation and Diversity, 2010
    Co-Authors: Donald L. J. Quicke, Ana M C Santos, Owen R Jones, Joaquin Hortal
    Abstract:

    .  1. Taxonomic and geographic biases are common in biodiversity inventories, especially in hyperdiverse taxa, such as the Ichneumonoidea. Despite these problems, biodiversity databases could be a valuable source of information if their reliability is carefully assessed. 2. One major problem of using these data for large-scale analyses is the unevenness of data quality from different areas, which makes them difficult to compare. One way of surpassing such problem would be to identify sets of areas that are evenly inventoried. 3. Here, we propose a scoring protocol for the identification of sets of evenly inventoried areas from taxonomic databases, based on three criteria: (i) completeness at high taxonomic levels, (ii) congruence with well-established ecological relationships (such as species–area relationship), and (iii) publication effort received. We apply this protocol to the selection of a set of evenly inventoried islands worldwide for two Ichneumonoidea families (Braconidae and Ichneumonidae) from the data gathered in Taxapad database. 4. From the 118 islands included in Taxapad, 53 and 70 can be considered sufficiently inventoried for Braconidae and Ichneumonidae, respectively. The publication effort criterion was more restrictive than the other two criteria. The Indomalayan, Nearctic and Palearctic regions had more than half of their islands identified as evenly inventoried, for both families. 5. We discuss the generality of the biases and incompleteness of most biodiversity data, and also how the basic principles of the protocol proposed here can be applied to taxonomic databases devoted to other taxa. Also, the islands identified here can serve as the basis for large-scale analyses of the poorly known biogeography of the Ichneumonoidea.

  • discovery of calcium enrichment in cutting teeth of parasitic wasp ovipositors hymenoptera Ichneumonoidea
    African Entomology, 2004
    Co-Authors: Donald L. J. Quicke, J Palmerwilson, A Burrough, Gavin R Broad
    Abstract:

    Energy dispersion X-ray spectrometry of the ovipositor tips of two species of parasitic wasps, Gabunia sp. (Ichneumonidae : Cryptinae) from Uganda and the cosmopolitan Heterospilus prosopidis (Braconidae : Doryctinae) show that they have high concentrations of calcium as well as of manganese associated with the apex of the lower ovipositor valve and in the former, specifically with the lower valve teeth. Previous studies had revealed only manganese in the ovipositors of ichneumonoids, and the discovery of highly calcium-enriched cutting teeth might indicate the involvement of biomineralization, in addition to transition metal-protein complexes, in cuticular hardening in these parasitic wasps. Comparisons with related taxa indicate that the calcium enrichment is not present in all members of their groups.

  • cocoon silk chemistry in parasitic wasps hymenoptera Ichneumonoidea and their hosts
    Biological Journal of The Linnean Society, 2004
    Co-Authors: Donald L. J. Quicke, Mark R Shaw
    Abstract:

    Bulk amino acid compositions of larval cocoon silks of 24 species of ichneumonoid parasitic wasps, representing 13 subfamilies that kill the host in a larval or prepupal stage, are compared with those of their hosts to test the hypothesis that amino acid compositions of major protein products should, in certain cases, be similar on energetic grounds. Although substantial variation in amino acid composition was found among both parasitoids and hosts, suggesting the production of different types of silks, no significant general matching was detected. However, the trend in the degree of similarity observed was in the direction predicted by a priori consideration of the nature of the parasitoid – host association. Lack of a general association may be explained by the very simple silk glands of the parasitic wasps and by the fact that, in most cases, their hosts are not completely consumed at a time when they are likely to contain any large reserves of silk proteins. The three species of Cotesia (Braconidae: Microgastrinae) investigated stood out in that their silks showed considerable interspecific variation in molar percentage amino acid composition, and this might be associated with their apparent utilization of -helical silks rather than fibroins

  • analise da riqueza da fauna de braconidae hymenoptera Ichneumonoidea em remanescentes naturais da area de protecao ambiental apa de descalvado sp
    Revista Brasileira De Entomologia, 2003
    Co-Authors: Katia Resende Netto Cirelli, Angelica Maria Penteadodias
    Abstract:

    Analysis of the Braconidae (Hymenoptera: Ichneumonoidea) fauna richness in natural remnants of the Area de Protecao Ambiental (APA) of Descalvado, SP. A survey of the Braconidae fauna on fragmentary natural environments at northeast Sao Paulo State was conducted using Malaise traps installed in five sites of Area de Protecao Ambiental of Descalvado. A total of 2,262 specimens, representing 22 subfamilies and 94 genera, was sampled throughout a period of sixteen months (from May, 1999 to August, 2000). Biological data were obtained from current literature and behavior patterns of host utilization for the studied fauna, mainly Braconidae which have been successful in control of agricultural insect pests. Statistical analyses indicated that the asymptote of the genera richness has been approached using this sampling method. This is the most complete survey yet available from natural fragmentary areas of the Descalvado Braconidae fauna. Patterns of distribution and richness of the Braconidae genera were established. Cluster Analysis was adopted taking as attribute the number of Braconidae genera.

    Abstract:

    Phenology of the Braconidae (Hymenoptera, Ichneumonoidea) at Area de Protecao Ambiental of Descalvado, Sao Paulo State. The flight phenology of the Braconidae fauna was conducted using Malaise traps in five sites of the Environmental Protected Area of Descalvado. A total of 2,792 specimens, representing 22 subfamilies, was sampled throughout a period of sixteen months from May, 1999 to August, 2000. The traps catches for koinobionts peak was in August, 1999 a month before of the idiobionts peak and in June, 2000 both peaks were simultaneous. The phenological peaks of dominant koinobiont taxa (Microgastrinae) were similar to all koinobionts, and the peaks of dominant idiobiont taxa (Doryctinae) were similar to all idiobionts, as well. December, 1999 and February, 2000 were the richer months in number of subfamilies (N= 19 and 18, respectivaly), corresponding to the same period when the subfamilies which potentially attack Lepidoptera where collected. The number of females was superior to the number of males and this relation was more accentuated in koinobionts. The peaks of both females and males were similar to dominate koinobiont and idiobionte taxa.

  • primer reporte de la familia braconidae hymenoptera Ichneumonoidea en los parques cerro saroche y terepaima estado lara venezuela

    Co-Authors: Rosa Briceno, Daylu Torres, Alejandro Zaldivarriveron
    Abstract:

    First survey of the family Braconidae (Hymenoptera: Ichneumonoidea) for the National Parks Cerro Saroche and Terepaima in Lara State, Venezuela The vast majority of members of the family Braconidae are parasitoids that act as natural regulators of other insects. Most of the reports come from mountain areas. However, little is known of these insects in arid and semi-arid areas, or dry environments, of Venezuela. This study was carried out in two natural ecosystems of Lara State (National Parks Cerro Saroche, PNCS, and Terepaima, PNT) in order to appreciate the biological composition of this family in those environments. For sampling, yellow traps were placed at two elevation points within each locality. We identified 13 subfamilies of Braconidae: Alysiinae, Blacinae, Doryctinae, Cenocoelinae, Cheloninae, Euphorinae, Helconinae, Hormiinae, Meteorinae, Microgastrinae, Opiinae, Orgilinae and Rogadinae. Likewise 20 genera were identified within the main four subfamilies (Doryctinae, Alysiinae, Cheloninae, and Rogadinae). In both parks the subfamily Doryctinae was the most important, followed by Alysiinae in PNT and Cheloninae in PNCS. The largest number of specimens occurred at 1200 meters elevation in both locations, and PNT was the park with the
