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 …

Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein

UCARE Research Products

To better understand the ecology and epidemiology of the wheat curl mite (Aceria tosichella Keifer) as a vector of wheat streak mosaic virus (WSMV), it is necessary to develop a method to confine the microscopic mites and their infection to specific areas of their host plants, particularly wheat and corn. In this study, corn was the plant of interest. The device developed for this mite-confining method was made by removing the lens of a phone camera lens clip and gluing a 2.5 cm x 4.5 cm piece of wood to the other arm of the clip. Clips were utilized by …

Evaluating Larval Movement And Infestation Of Soybean Gall Midge, Genereuse Turabawe, Débora Goulart Montezano, Anthony J. Mcmechan

UCARE Research Products

Soybean gall midge (SGM) Resseliellamaxima Gagnéis a newly identified insect pest of soybean (Gagnéet al 2019). As of August, 2019 a total of 92 counties across five midwestern states (Fig. 1) documented as infested. Heavily injured soybean fields show visible signs of dead or dying plants (Fig. 2a), causing significant economic losses for farmers.

Heavily injured soybean plants often die prematurely with several different larval stages (Fig. 2b) still feeding within the plant. Significant concern have been raised about the role of these larvae in infesting adjacent healthy plants.

To better understand the behavior and potential for larval infestation a …

Sorghum Tolerance Of Phloem-Feeding Aphids, Earl Agpawa, Sajjan Grover, Joe Louis

UCARE Research Products

Aphids are phloem sap-feeding insects that negatively affects plant productivity. With short generation times, new aphid biotypes may arise either in response to pesticide use or through other factors. Additional biotypes can cause serious damage to plants compared to others. Whereas others can become highly resistant to methods of pest control. One possible solution to this problem is to focus on the plant itself, or host plant resistance. Plant tolerance is one of the plant resistance categories in which the plant is capable of functioning normally and remain relatively unharmed and stable in response to insect herbivory without harming the …
