Drosophila suzukii (Matsumara) (Diptera: Drosophilidae), the spotted wing drosophila, is a global pest of soft fruits now rearable on a standard D. melanogaster (Meigen) diet containing the fly's own natural food: soft-skinned berries. The techniques tested here can save 40% of cultures from microbial contamination that develops after combining artificial food sources (e.g., standard drosophila media) with unsterilized host plant material (berries). A suitable ratio for mixing dietary ingredients for a vial or test-tube rearing system includes, by weight, 1 part berry tissue for oviposition, 1.5 parts dry diet media for carbohydrate, 7 parts clean water for moisture, and ∼5 …

Dispersal And Sampling Of The Wheat Stem Sawfly, Cephus Cintus Norton, (Hymenoptera: Cephidae), Christopher Mccullough
Department of Entomology: Dissertations, Theses, and Student Research
The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a serious insect pest of wheat, Triticum aestivum L., in the northern central Great Plains. The sawfly has been a pest of wheat in Montana, North Dakota, and Canada since the early 20th century. It was first detected in Nebraska winter wheat in the early 1990s, in Scotts Bluff County. The sawfly has since spread throughout the Nebraska Panhandle region and become a pest of serious concern. To gain a better understanding of the sawfly in Nebraska, investigations on the emergence, dispersal, and sampling of the sawfly were conducted. …
Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Library Map Prize
Species distribution modeling, which uses species-environment relationships to predict species’ geographic ranges, is a powerful technique for biogeographical and ecological analysis as well as for conservation planning. However, it has typically been underutilized for invertebrates and for freshwater species, as modeling these groups can pose unique challenges. Here I present methods for modeling odonate distributions and demonstrate these methods for four North American species. I show that incorporating expert-derived range maps as spatial priors can significantly improve model performance as compared to MaxEnt models. I also introduce a new distance to freshwater layer as an environmental variable, and show that …
