Whiting, Chair Sven Bradler Seth M. Bybee Steven D. Leavitt Department of Biology Brigham Young University Copyright © 2018 Yelena Marlese Pacheco All Rights Reserved ABSTRACT Ecomorph Convergence in Stick Insects (Phasmatodea) with Emphasis on the Lonchodinae of Papua New Guinea Yelena Marlese Pacheco Department of Biology, BYU Master of Science Phasmatodea exhibit a variety of cryptic ecomorphs associated with various microhabitats. Multiple ecomorphs are present in the stick insect fauna from Papua New Guinea, including the tree lobster, spiny, and long slender forms. While ecomorphs have long been recognized in phasmids, there has yet to be an attempt to objectively define and study the evolution of these ecomorphs. -

Hymenoptera (Stinging Wasps)
Return to insect order home Page 1 of 3 Visit us on the Web: www.gardeninghelp.org Insect Order ID: Hymenoptera (Stinging Wasps) Life Cycle–Complete metamorphosis: Queens or solitary adults lay eggs. Larvae eat, grow and molt. This stage is repeated a varying number of times, depending on species, until hormonal changes cause the larvae to pupate. Inside a cell (in nests) or a pupal case (solitary), they change in form and color and develop wings. The adults look completely different from the larvae. Solitary wasps: Social wasps: Adults–Stinging wasps have hard bodies and most have membranous wings (some are wingless). The forewing is larger than the hindwing and the two are hooked together as are all Hymenoptera, hence the name "married wings," but this is difficult to see. Some species fold their wings lengthwise, making their wings look long and narrow. The head is oblong and clearly separated from the thorax, and the eyes are compound eyes, but not multifaceted. All have a cinched-in waist (wasp waist). Eggs are laid from the base of the ovipositor, while the ovipositor itself, in most species, has evolved into a stinger. Thus only females have stingers.

Oblong head Compound eyes Folded wings but not multifaceted appear Cinched in waist long & narrow Return to insect order home Page 2 of 3 Eggs–Colonies of social wasps have at least one queen that lays both fertilized and unfertilized eggs. Most are fertilized and all fertilized eggs are female. Most of these become workers; a few become queens. -

Character Evolution and Microbial Community Structure in a Host-Associated Grasshopper
CHARACTER EVOLUTION AND MICROBIAL COMMUNITY STRUCTURE IN A HOST-ASSOCIATED GRASSHOPPER by TYLER JAY RASZICK B.S. University of Florida, 2010 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Biology in the College of Sciences at the University of Central Florida Orlando, Florida Spring Term 2014 © 2014 Tyler J. Raszick ii ABSTRACT The spotted bird grasshopper, Schistocerca lineata Scudder (Orthoptera: Acrididae), is a widely distributed species found throughout most of the continental United States and southern Canada. This species is known to be highly variable in morphology, with many distinct ecotypes across its native range. These ecotypes display high levels of association with type-specific host plants. Understanding the evolutionary relationships among different ecotypes is crucial groundwork for studying the process of ecological differentiation. I examine four ecotypes from morphological and phylogeographic perspectives, and look for evidence of distinct evolutionary lineages within the species. I also begin to explore the potential role of the microbial community of these grasshoppers in ecological divergence by using 454 pyrosequencing to see if the microbial community structure reflects the ecology of the grasshoppers. I find support for a distinct aposematic lineage when approaching the data from a phylogeographic perspective and also find that this ecotype tends to harbor a unique bacterial community, different from that of a single other ecotype. iii ACKNOWLEDGMENTS I would like to acknowledge my advisor H. Song of the University of Central Florida for mentorship throughout my degree, as well as my thesis committee, K. Fedorka and E. -

The evaluation of genetic relationships within Acridid grasshoppers (Orthoptera, Caelifera, Acrididae) on the subfamily level using molecular markers. Folia Biologica (Kraków) 67: 119-126. Over the last few decades, molecular markers have been extensively used to study phylogeny, population dynamics, and genome mapping in insects and other taxa. Phylogenetic methods using DNA markers are inexpensive, fast and simple to use, and may help greatly to resolve phylogenetic relationships in groups with problematic taxonomy. However, different markers have various levels of phylogenetic resolution, and it’s important to choose the right set of molecular markers for a studied taxonomy level. Acrididae is the most diverse family of grasshoppers. Many attempts to resolve the phylogenetic relationships within it did not result in a clear picture, partially because of the limited number of molecular markers used. We have tested a phylogenetic resolution of three sets of the most commonly utilized mitochondrial molecular markers available for Acrididae sequences in the database: (i) complete protein-coding mitochondrial sequences, (ii) concatenated mitochondrial genes COI, COII, and Cytb, and (iii) concatenated mitochondrial genes COI and COII. -

Summary 2. Study area 3. Avian fauna and conservation status of threatened bird species 4. Habitat analysis 5. Ecological assessment and community education 6. Outputs 7. Main references 8. Acknowledgements 1. Summary Laojunshan Nature Reserve is located at Yibin city, Sichuan province, south China. It belongs to eastern part of Liangshan mountains and is among the twenty-five hotspots of global biodiversity conservation. The local virgin alpine subtropical deciduous forests are abundant, which are actually rare at the same latitudes and harbor a tremendous diversity of plant and animal species. It is listed as a Global 200 ecoregion (WWF), an Important Bird Area (No. CN205), and an Endemic Bird Area (No. D14) (Stattersfield, et al . 1998). However, as a nature reserve newly built in 1999, it is only county-level and has no financial support from the central government. Especially, it is quite lack of scientific research, for example, the avifauna still remains unexplored except for some observations from bird watchers. Furthermore, the local community is extremely poor and facing modern development pressures, unmanaged human activities might seriously disturb the local ecosystem. We conducted our project from April to June 2007, funded by Conservation Leadership Programme. Two fieldwork strategies were used: “En bloc-Assessment” to produce an avifauna census and ecological assessments; "Special Survey" to assess the conservation status of some threatened endemic bird species. -
Insect Classification Standards 2020
RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification. -

ZooKeys 713: 25–52. https://doi.org/10.3897/zookeys.713.15118 Abstract Based on samples collected during surveys of Brazilian cave fauna, seven earwig species are reported: Cy- lindrogaster cavernicola Kamimura, sp. n., Cylindrogaster sp. 1, Cylindrogaster sp. 2, Euborellia janeirensis, Euborellia brasiliensis, Paralabellula dorsalis, and Doru luteipes, as well as four species identified to the (sub) family level. To date, C. cavernicola Kamimura, sp. n. has been recorded only from cave habitats (but near entrances), whereas the other four organisms identified at the species level have also been recorded from non-cave habitats. Wings and female genital structures of Cylindrogaster spp. (Cylindrogastrinae) are examined for the first time. The genital traits, including the gonapophyses of the 8th abdominal segment shorter than those of the 9th segement, and venation of the hind wings of Cylindrogastrinae correspond to those of the members of Diplatyidae and not to Pygidicranidae. -

Journal of Hymenoptera Research 83: 73–99. https://doi.org/10.3897/jhr.83.64018 Abstract The Braconidae are a megadiverse and ecologically highly important group of insects. The vast majority of braconid wasps are parasitoids of other insects, usually attacking the egg or larval stages of their hosts. The ovipositor plays a crucial role in the assessment of the potential host and precise egg laying. We used light- and electron-microscopic techniques to investigate all inherent cuticular elements of the ovipositor (the female 9th abdominal tergum, two pairs of valvifers, and three pairs of valvulae) of the braconid Habrobra- con hebetor (Say, 1836) in detail with respect to their morphological structure and microsculpture. Based on serial sections, we reconstructed the terebra in 3D with all its inherent structures and the ligaments connecting it to the 2nd valvifers. -
