This massive microgastrine material is available in Dr. James Whitfield’s laboratory at the University of Illinois, Urbana-Champaign (UIUC) and was the fundamental for my research. Chapter 1 is focused on the first taxonomic revision of Neotropical Glyptapanteles species from Costa Rica and Ecuador. Here, I describe 137 new species, 78 from Costa Rica and 59 from Ecuador. The taxonomic revision includes an extensive morphological image library for each of the species described and consists of about 2,331 high-resolution images which were used to create 223 plates. The pictures were obtained by both scanning electron microscope (SEM) and Z-stacked images merging different focus positions. The reference collection for this study comprises a total of 16,663 specimens, of which 13,540 are preserved in 100% ethanol and 3,123 are point mounted. Most of the species described (91 spp.) are completely gregarious while 28 are exclusively solitary, nine species exhibited both solitary and gregarious lifestyles and the remaining nine species were collected by Malaise traps. Three different sets of data (morphology, host records and DNA barcoding) were integrated in order to generate accurate boundaries between species. In Chapter 2, the first Glyptapanteles phylogeny based on morphological and molecular data from fragments of four genes is presented. The genes include mitochondrial COI (cytochrome c oxidase subunit 1) and three nuclear genes: Alpha-spectrin; long-wavelength opsin (LW Rh) and wg (wingless). All the Costa Rican material had associated COI, sequences generated partly by the collaborators in the Biodiversity Institute of Ontario, University of Guelph, Canada and partly by the Keck Center, UIUC. In contrast, COI sequences for Ecuador material and all nuclear genes were generated at UIUC. Phylogeny estimation included maximum likelihood and Bayesian inference. The most well supported phylogenetic reconstruction revealed two discrete clades, and although support was low at basal nodes, relationships at intermediate and terminal nodes were resolved with high support. The majority of the parasitoid samples are endowed with information about their herbivore hosts as well as host plants, providing information across three trophic levels. Mapping this information onto the phylogeny revealed patterns of niche conservatism in one of the clades. It was revealed that host preferences of Glyptapanteles are concentrated primarily in exposed feeding Macrolepidoptera, although ancestrally they explored Microlepidoptera.","abstract_html":"Among hymenopteran parasitoid wasps, Ichneumonoidea is one of the superfamilies with the highest number of species and includes the highly diverse Microgastrinae subfamily.

The taxonomic revision includes an extensive morphological image library for each of the species described and consists of about 2,331 high-resolution images which were used to create 223 plates. The pictures were obtained by both scanning electron microscope (SEM) and Z-stacked images merging different focus positions. The reference collection for this study comprises a total of 16,663 specimens, of which 13,540 are preserved in 100% ethanol and 3,123 are point mounted. Most of the species described (91 spp.) are completely gregarious while 28 are exclusively solitary, nine species exhibited both solitary and gregarious lifestyles and the remaining nine species were collected by Malaise traps. Three different sets of data (morphology, host records and DNA barcoding) were integrated in order to generate accurate boundaries between species. In Chapter 2, the first Glyptapanteles phylogeny based on morphological and molecular data from fragments of four genes is presented. The genes include mitochondrial COI (cytochrome c oxidase subunit 1) and three nuclear genes: Alpha-spectrin; long-wavelength opsin (LW Rh) and wg (wingless). All the Costa Rican material had associated COI, sequences generated partly by the collaborators in the Biodiversity Institute of Ontario, University of Guelph, Canada and partly by the Keck Center, UIUC. In contrast, COI sequences for Ecuador material and all nuclear genes were generated at UIUC. Phylogeny estimation included maximum likelihood and Bayesian inference. The most well supported phylogenetic reconstruction revealed two discrete clades, and although support was low at basal nodes, relationships at intermediate and terminal nodes were resolved with high support. The majority of the parasitoid samples are endowed with information about their herbivore hosts as well as host plants, providing information across three trophic levels. Mapping this information onto the phylogeny revealed patterns of niche conservatism in one of the clades. It was revealed that host preferences of Glyptapanteles are concentrated primarily in exposed feeding Macrolepidoptera, although ancestrally they explored Microlepidoptera.","Item withdrawn by Laura Spradlin (lspradl2@illinois.edu) on 2014-12-01T14:17:01Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 34 Arias_Diana.pdf: 2773915 bytes, checksum: 3cc3f6563cd38bea6b7d94063c1b4e25 (MD5) Arias_Diana.pdf: 2773974 bytes, checksum: c7f52b2b1657bf31049fd223522aa0a2 (MD5) Appendix_B-24Figures.zip: 16671986 bytes, checksum: 155186171f907dcc49f7d1622b004a7c (MD5) Arias_Diana.pdf: 2773708 bytes, checksum: a905b17d1a97d0150a1d1e69e8defaeb (MD5) Appendix_B-21Figures.zip: 35477791 bytes, checksum: b1ca24d53a6f28fd97150d3241bf045b (MD5) Appendix_B-20Figures.zip: 51638072 bytes, checksum: 59e116c3564983c0627e80ea950057db (MD5) Appendix_B-19Figures.zip: 32331445 bytes, checksum: 565a77fd4e79c774ca048d07d1008d75 (MD5) Appendix_B-18Figures.zip: 36418998 bytes, checksum: 06844ee99831aa619c2126365c20ea74 (MD5) Appendix_B-17Figures.zip: 47633114 bytes, checksum: b68f8d68a140900640cc8d393d1111ab (MD5) Appendix_B-16Figures.zip: 39947567 bytes, checksum: 04c9d678700de4522c1f3f90b9b0cfeb (MD5) Appendix_B-15Figures.zip: 41133115 bytes, checksum: 0049b18679c6fffd79fdb90e8da91ff2 (MD5) Appendix_B-14Figures.zip: 40938460 bytes, checksum: 96893d4601a5c489df9f8dd12fbff71c (MD5) Appendix_B-13Figures.zip: 45140705 bytes, checksum: 3886fa17e850b9eee6aa2fc7ce5d7615 (MD5) Appendix_B-12Figures.zip: 43806831 bytes, checksum: 5853ef830e02bca49d4f228cfc67addf (MD5) Appendix_B-11Figures.zip: 70991983 bytes, checksum: 8a1bb5563812fb6cdffb7b045bf7f395 (MD5) Appendix_B-10Figures.zip: 48726818 bytes, checksum: cb522d0fd58e770dcf3b272897a2118f (MD5) Appendix_B-9Figures.zip: 33165376 bytes, checksum: a3a4e50d8b28350e2ef68c268cf90c81 (MD5) Appendix_B-8Figures.zip: 33239313 bytes, checksum: 7937950c75b47aca86990488e94a491b (MD5) Appendix_B-7Figures.zip: 41223920 bytes, checksum: 8d8f6ba9b8ea54c47a5c20647adc5d6a (MD5) Appendix_B-6Figures.zip: 39799497 bytes, checksum: 6f8d1d2fbba89a207bc52aa145988758 (MD5) Appendix_B-5Figures.zip: 45721508 bytes, checksum: f4b6bdb10e7df13a5d823c3c7a2227d3 (MD5) Appendix_B-3Figures.zip: 55677309 bytes, checksum: 77a45a1f9f8f21800f256a798fc82276 (MD5) Appendix_B-4Figures.zip: 166584090 bytes, checksum: 9a628bcd21fbd28e2ceab4f2e9cab842 (MD5) Appendix_B-22Figures.zip: 158447232 bytes, checksum: 9e1201db195b845a88dac861caa6ae8e (MD5) Appendix_B-23Figures.zip: 14705684 bytes, checksum: b4eec06c3ee4f66e0f0cfe2fb84a3b76 (MD5) Appendix_B-2Figures.zip: 169039131 bytes, checksum: 15695a92bd2322290f1c83f5dd145c18 (MD5) 0_Appendix_B-1Figures.zip: 167649085 bytes, checksum: 1cc3061ea8210128df96135d0b4e5a95 (MD5) Appendix_H_Molecular Datasets.zip: 133451 bytes, checksum: 47dc6b23174ccd341cf0a296e02a95c2 (MD5) Appendix_F_Character list Glyptapanteles.docx: 79392 bytes, checksum: 6e1911cc862e2d3373214efce87a2c9a (MD5) Appendix_C_Holotypes.xlsx: 59595 bytes, checksum: ac63db1a13ffddd70decb8ec5681c477 (MD5) Appendix_G_Glyptapanteles_DNA_extraction.xlsx: 22903 bytes, checksum: 8255560ba28f23a137c57c113104c0fc (MD5) Appendix_E_COI_CR&EC.txt: 864312 bytes, checksum: 0a5631eb6e716384b6880c77e62d6076 (MD5) Appendix_D_Paras-Herb-Plant_host.xlsx: 97385 bytes, checksum: 4f7617c3dfc4da054d682d7ff0b6e591 (MD5) Appendix_A_Material-examined.xlsx: 121482 bytes, checksum: 536ee7634d585820f09f8b0944e37353 (MD5)","Made available in DSpace on 2015-01-21T19:55:55Z (GMT).
