Genomes of the Hymenoptera Abstract Hymenoptera is the second-most sequenced arthropod order, with 52 publically archived genomes (71 with ants, reviewed elsewhere), however these genomes do not capture the breadth of this very diverse order (Figure 1, Table 1). These sequenced genomes represent only 15 of the 97 extant families. Although at least 55 other genomes are in progress in an additional 11 families (see Table 2), stinging wasps represent 35 (67%) of the available and 42 (76%) of the in progress genomes.

E-mail: [email protected] 2Department of Entomology, Royal Ontario Museum, Toronto, Ontario, Canada, M5S 2C6 and Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada, M5S 1A. E-mail: [email protected] Abstract Palaeocharis rex n. gen. and sp. (Eucharitidae: Eucharitinae) and Perilampus pisticus n. sp. (Perilampidae: Perilampinae) are described from Baltic amber. Perilampus renzii (Peñalver & Engel) is transferred to Torymidae: Palaeotorymus renzii n. comb. Palaeocharis is related to Psilocharis Heraty based on presence of one anellus, linear mandibular depression, dorsal axillular groove, free prepectus and a transverse row of hairs on the hypopygium. This fossil is unique in comparison with extant Chalcidoidea because there are two foretibial spurs instead of a single well- developed calcar. Perilampus pisticus is placed into the extant Perilampus micans group because the frenum and marginal rim of the scutellum are visible in dorsal view and the prepectus forms a large equilateral triangle. The phylogenetic placement of both genera is discussed based on an analysis of both a combined morphological and molecular (28S and 18S) and morphology-only matrix. Morphological characters were used from an earlier study of Eucharitidae (Heraty 2002), with some characters revised to reflect variation in Perilampinae. Baltic amber is of Eocene age, which puts the age of divergence of these families at more than 40 mya.

  • Hymenoptera: Braconidae)
    Archives of Insect Biochemistry and Physiology 54:95–109 (2003) Novel Diterpenoids and Hydrocarbons in the Dufour Gland of the Ectoparasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) Ralph W. Howard,1* James E. Baker,1 and E. David Morgan2 Chemical constituents contained in the Dufour gland of the ectoparasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) were characterized. Three terpenes, b-springene, a homo-b-springene, and a homo-geranyllinalool constitute approximately 37% of the gland components, with the remaining 63% all being hydrocarbons. The hydrocarbons consist of a homologous series of n-alkanes (n-C21 to n-C31), a trace amount of 3-methyl C23, a homologous series of internally methyl-branched alkanes (11-methyl C23 to 13-methyl C35), one dimethylalkane (13,17-dimethyl C33), a homologous series of monoenes (C25:1 9 13 15 13 15 to C37:1) with the double bonds located at D , D and D for alkenes of carbon number 25 to 31 and at D and D for carbon numbers 33 to 37 and three homologous dienes in very low amounts with carbon numbers of 31, 32, and 33. The terpenoid and hydrocarbon composition of the Dufour gland was similar in virgin and mated females. However, in contrast to the hydrocarbons, the amount of b-springene and homo-geranyllinalool increased significantly with time after adult emer- gence from the cocoon. Although many hydrocarbons in the Dufour gland are the same as those on the cuticle of this species [Howard and Baker, Arch. Insect Biochem. Physiol. 53:1–18 (2003)], substantial differences also occur. Of particular note is the chain length of alkenes and location of the double bonds: cuticular alkenes have a chain length of C23 to C29 and double bond locations at D5, D7, and D9, whereas the Dufour gland alkenes contains a greater range of carbon numbers and have no D5 or D7 alkenes.

  • The Origins of Species Richness in the Hymenoptera: Insights from a Family-Level Supertree BMC Evolutionary Biology 2010, 10:109
    Davis et al. BMC Evolutionary Biology 2010, 10:109 http://www.biomedcentral.com/1471-2148/10/109 RESEARCH ARTICLE Open Access TheResearch origins article of species richness in the Hymenoptera: insights from a family-level supertree Robert B Davis*1,2, Sandra L Baldauf1,3 and Peter J Mayhew1 Abstract Background: The order Hymenoptera (bees, ants, wasps, sawflies) contains about eight percent of all described species, but no analytical studies have addressed the origins of this richness at family-level or above. To investigate which major subtaxa experienced significant shifts in diversification, we assembled a family-level phylogeny of the Hymenoptera using supertree methods. We used sister-group species-richness comparisons to infer the phylogenetic position of shifts in diversification. Results: The supertrees most supported by the underlying input trees are produced using matrix representation with compatibility (MRC) (from an all-in and a compartmentalised analysis). Whilst relationships at the tips of the tree tend to be well supported, those along the backbone of the tree (e.g. between Parasitica superfamilies) are generally not. Ten significant shifts in diversification (six positive and four negative) are found common to both MRC supertrees. The Apocrita (wasps, ants, bees) experienced a positive shift at their origin accounting for approximately 4,000 species. Within Apocrita other positive shifts include the Vespoidea (vespoid wasps/ants containing 24,000 spp.), Anthophila + Sphecidae (bees/thread-waisted wasps; 22,000 spp.), Bethylidae + Chrysididae (bethylid/cuckoo wasps; 5,200 spp.), Dryinidae (dryinid wasps; 1,100 spp.), and Proctotrupidae (proctotrupid wasps; 310 spp.). Four relatively species-poor families (Stenotritidae, Anaxyelidae, Blasticotomidae, Xyelidae) have undergone negative shifts.

Comparative Cytogenetics 14(3): 399–416. https://doi.org/10.3897/CompCytogen.v14i3.56535 Abstract An overview of the current knowledge of chromosome sets of the parasitoid superfamily Chalcidoidea is given. Karyotypes of approximately 240 members of this group, i.e. just above one percent of described species, are studied up to now. Techniques for obtaining and analyzing preparations of chalcid chromo- somes are outlined, including the so-called “traditional” and “modern” methods of differential staining as well as fluorescence in situ hybridization (FISH). Among the Chalcidoidea, the haploid chromosome number can vary from n = 3 to n = 11, with a clear mode at n = 6 and a second local maximum at n = 10. In this group, most chromosomes are either metacentric or submetacentric, but acrocentrics and/ or subtelocentrics also can predominate, especially within karyotypes of certain Chalcidoidea with higher chromosome numbers. The following main types of chromosomal mutations are characteristic of chal- cid karyotypes: inversions, fusions, translocations, polyploidy, aneuploidy and B chromosome variation.

    Habitat-based drivers of arthropod abundance and richness in an intensively farmed agricultural landscape by Aleksandra Dolezal A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada © Aleksandra Dolezal, July 2019 ABSTRACT HABITAT-BASED DRIVERS OF ARTHROPOD ABUNDANCE AND RICHNESS IN AN INTENSIVELY FARMED AGRICULTURAL LANDSCAPE Aleksandra Dolezal Advisor: University of Guelph, 2019 Dr. A. S. MacDougall Habitat is critical for sustaining arthropod populations, but its influence in agricultural landscapes where arthropods are declining is unclear. In a heavily farmed area of Ontario, I examined habitat effects on arthropods at two scales: landscape (habitat isolation) and local (farm cover type -crop, prairie, forest). Additional analyses tested differences in arthropod communities among cover types, how prairie addition affects leaf defoliation, whether crop type influences arthropods (soy, corn, orchard, mixed organic), and whether arthropod richness differs between farm and non-farm sites. I found arthropod richness and abundance to be determined locally, via the presence of restored high-quality prairie habitat. Prairie addition did not affect leaf defoliation but influenced the spatial distribution of herbivores in crops. Crop type influenced arthropod groups, especially herbivores, which preferred mixed organic cover. Lastly, farm and non-farm sites revealed similar family-level richness, suggesting that conventional farms can support arthropod biodiversity if habitat is not limiting. iii ACKNOWLEDGEMENTS This thesis would not have been possible without the researchers who came together to initiate an extraordinary project that was the basis for my work. It’s their guiding idea and the efforts of all the participating scientists and non-scientists which make this project an on-going success.
