Prevalence of Gregarine Protozoa Infection in Zygoptera Sourced from Varying Collection Sites in Keith County, Nebraska

B.G Kircher II, A. Kadubandi, and S.L. Gardner S. H.W. Manter Laboratory of Parasitology, University of Nebraska-Lincoln and Cedar Point Biological Station, University of Nebraska-Lincoln

Damselflies are ubiquitous flying insects of the order Odonata with thousands of species found around the world. The parasites associated with damselfly species are equally as ubiquitous, with the most common being gregarine protozoa and water mites, though other parasitic organisms such as trematodes are also found in these animals. Gaining an understanding of the relationships among hosts and …

How Do Vanhorniidae (Hymenoptera) Parasitize Eucnemidae (Coleoptera)?, Jyrki Muona

Insecta Mundi

The relationship between the beetle family Eucnemidae and the parasitic proctotrupoid family Vanhorniidae is discussed. The only proven host for Vanhornia eucnemidarum Crawford in North America is an undetermined species of the genus Isorhipis Boisduval and Lacordaire. In Europe, the only known host for Vanhornia leileri Hedqvist is Hylis cariniceps (Reitter). The biologies of the hosts differ radically and it ap­pears unlikely that they could be parasitized in a typical proctotrupoid fashion in which eggs are placed in or on the host larva. This supports the hypothesis that small Vanhorniidae larvae attach themselves to the newly hatched beetle larvae, before …

Gut Symbiont Viability In Honey Bees Exposed To Agrochemical Stressors, Bryant Justin Gabriel

Department of Entomology: Dissertations, Theses, and Student Research

The honey bee gut microbiome is essential for protecting this pollinator against abiotic and biotic stressors, including the prevention of harmful gut parasites and pathogens. Previous studies have not only demonstrated a linkage of bee gut dysbiosis to increased immunodeficiencies and pathogen sensitivities, but also report the maladaptation of the gut microbiome in bees exposed to agricultural and apicultural chemistries. There are few techniques available that allow for a simple and reliable analysis of the relative proportions of live and dead gut microbes in bees exposed to these chemistries. Previous techniques for measuring gut symbiont dysbiosis are temporally limited by …

Episodic Radiations In The Fly Tree Of Life, Brian M. Wiegmann, Michelle D. Trautwein, Isaac S. Winkler, Norman B. Barr, Jung-Wook Kim, Christine Lambkin, Matthew Bertone, Brian Cassel, Keith Bayless, Alysha Heimberg

Dartmouth Scholarship

Flies are one of four superradiations of insects (along with beetles, wasps, and moths) that account for the majority of animal life on Earth. Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms, yet recent research has suggested that fly relationships have been obscured by multiple episodes of rapid diversification. We provide a phylogenomic …

Only Large Amounts Of Powdered Sugar Applied Directly To Brood Cells Harms Immature Honey Bees, Nicholas P. Aliano, Marion D. Ellis

Department of Entomology: Faculty Publications

We applied measured amounts of powdered sugar directly to honey bee brood combs containing eggs and larvae of known age groups. 24 h later, we compared powdered sugar-treated brood with similarly aged cohorts of immature bees that did not receive powdered sugar. Low and high doses of powdered sugar (0.3 and 0.6 g per 151.5 ± 1.0 cells, respectively) caused significant egg removal of 62.2 ± 5.1% and 86.1 ± 5.1%, respectively, when compared to eggs that received no powdered sugar (t = 16.91; df = 29; P = 0.0001). Powdered sugar had no effect on 5-day-old honey bee larvae …
