ARTHROPOD COMMUNITIES and PASSERINE DIET: EFFECTS of SHRUB EXPANSION in WESTERN ALASKA by Molly Tankersley Mcdermott, B.A./B.S
Arthropod communities and passerine diet: effects of shrub expansion in Western Alaska Item Type Thesis Authors McDermott, Molly Tankersley Download date 26/09/2021 06:13:39 Link to Item http://hdl.handle.net/11122/7893 ARTHROPOD COMMUNITIES AND PASSERINE DIET: EFFECTS OF SHRUB EXPANSION IN WESTERN ALASKA By Molly Tankersley McDermott, B.A./B.S.

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -

Interesting Early Stages of Some Sri Lankan Moths Typical Moth Life Cycle
Interesting early stages of some Sri Lankan Moths Typical Moth Life Cycle A Cocoon is a casing of spun silk produced by many insects to form a protective covering for the Pupa. Many Moth Caterpillars for example produce silk cocoons. Cocoons can be of various types, from hard to soft, with various colours dependent on the species involved. Wingless Females Some female moths of the Subfamily Lymantriinae are flightless. Male Female Orgyia sp. Lymantria sp. Life Cycle of Lymantria ampla Life cycle of Fir tussock moth (Orgyia detrita) Ant-mimic Moth caterpillars • Caterpillars in the moth genus, Homodes Guenée have been documented to be closely associated with weaver ants, as well as resembling them in terms of morphology and behaviour (Shelford, 1902, 1916; Kalshoven, 1961; Common, 1990; Holloway, 2005). In Sri Lanka, at least three species have been previously recorded • Homodes fulva • Homodes crocea Homodes crocea • Homodes vivida Dorsal (a) and posterior (b) views of the raised rear end of the caterpillar, Lobster Moth (Stauropus alternus) • First instar larva is a very good ant mimic both in appearance and behaviour • Resting posture of its mid instar look like an irregularly curved, dead leaf. • This resemblance to dried or dead leaf debris is certainly applicable to the later instars as well. Bagworms (Psychidae) • The bagworm family (Lepidoptera: Psychidae) includes approximately 1000 species, all of which complete larval development within a self enclosing bag. • In Sri Lanka 23 species have been recorded in this family • Some bagworms are specialized in their host plants (monophagous) , while others can feed on a variety of plant species (polyphagous) Eumeta variegata • A bagworm begins to build its case as soon as it hatches. -

Tachinids (Diptera: Tachinidae) Reared from Lepidopterous Hosts in Kayseri Province with New Host Records

Two of the hosts are recorded for the first time. These two host-parasitoid couples are Apterogenum ypsillon (Denis and Schiffermüller, 1775) (Noctuidae) for Pales pavida (Meigen, 1824) and Ephelis cruentalis (Geyer, 1832) (Pyralidae) for Clemelis pullata (Meigen, 1824). Also, four new host records for Turkey were identified. Key words: Tachinidae, Lepidoptera, new host records, Kayseri, Turkey. INTRODUCTION Tachinidae is one of the largest families of Diptera with about 8,500 species (O’Hara 2013). The family gains importance in agricultural and forest fields ecologically and economically because all of the species of this family are parasitoids of insects and other arthropods. Many hosts are lepidopteran pests, some of which cause considerable damage unless they are controlled. Other hosts are species that belong to the orders Coleoptera, Hemiptera, Hymenoptera, Orthoptera, Diptera and Lithobiomorpha (Grenier, 1988; Stireman et al., 2006; Tschorsnig, 2017). Many hosts are still unknown. Detailed information on West Palaearctic hosts can be found in Herting (1960), Tschorsnig and Herting (1994), Kara and Tschorsnig (2003), Vaňhara et al. -

Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect.
