 Nocturnal Moth Pollinators in Fruit Production

Stephen is working to identify the role of nocturnal moth pollinators in fruit production. This group of pollinators is virtually unexplored in agriculture, and Stephen hopes to provide some insight into this system.

 Dylan Cleary

Dylan Cleary | Cleary CV | Advisor: Allen Szalanski

Insect Genetics Lab

Dylan is using molecular diagnostics to detect the presence of various parasites and pathogens of honey bees in samples from Arkansas and Oklahoma. Specifically, she is detecting for Nosema apis, Nosema ceranae, Spiroplasma melliferum, Spiroplasma apis, Crithidia mellificae, Lotmaria passim, and Varroa destructor.


Lizzy Herrera

Lizabeth Herrera | Herrera CV | Advisor: Donn Johnson

Sustainable Fruit Entomology

Lizzy is working to develop organic management strategies against the invasive fruit pest spotted wing drosophila (Drosophila suzukii). She is also looking at potential alternative wild hosts for spotted wing in the Northwest Arkansas region. 

 Rosalee Knipp

Rosalee Knipp | Knipp CV | Advisor: Donald Steinkraus

Spotted Wing Drosophila

Rosalee works with an invasive fruit fly pest spotted wing drosophila (SWD), (Drosophila suzukii) to better understand how and where they are overwintering in Arkansas. She is also working to see if an entomopathogenic fungus Beauveria bassiana can be used to help control this pest.

 MaryKate Williams

MaryKate Williams | Williams CV | Advisor: Allen Szalanski

Honey Bee Trypanosomes

MaryKate studies honey bee trypanosomes from managed and feral honey bee populations in the United States using molecular techniques. One goal of her thesis is to determine the prevalence of Crithidia mellificae and Lotmaria passim. In a future study she plans to determine pathogen longevity and an infectious dose of trypanosomes for honey bees.
