Abstract Details

2022, Master of Science, Ohio State University, Entomology.
Honey bees are exposed to an array of potentially toxic chemicals, which differ in aspects of their toxicity as well as their fate in the environment. In Chapter 1 of my thesis, I discuss the exposure and effects of toxic chemicals to honey bees through the lens of chemical kinetics. I also describe applications of kinetic modeling for the development of mechanistic models of colony exposure. In chapter 2, I demonstrate how kinetic modeling (toxicokinetic-toxicodynamic modeling) can be used to predict the long-term effects of chemical exposure on the survival of individual honey bees and the growth of their colonies. I focus on metal pollutants (As, Cd, Li, Pb, and Zn), which honey bees are exposed to in a range of human modified environments. I found that a toxicokinetic-toxicodynamic model (the General Unified Thresholds Model of Survival, GUTS) better predicted the survival of honey bees in the lab than a simple extrapolation of a standard (probit) model that is commonly used in honey bee risk assessments. When predicting the effects of metal exposure on colony growth, differences between modeling approaches were highly case-specific. In chapter 3, I focus on the exposure and effects of metals to immature honey bees. Specifically, I describe an experiment using queen-rearing boxes to measure the accumulation of metals into larval food (nurse jelly) and developing queen larvae. I also describe a laboratory study on the toxicity of different metals to honey bee larvae reared in vitro. I found that Cd and Li translocate into larval foods at a higher rate than has been observed for pesticides. Furthermore, when applied to the larval diet in vitro, As, Li, and Zn affected the survival of honey bee larvae at field-relevant concentrations.
