Toxicological Analysis of Acaricides for Varroa Mite Management
The varroa mite is a primary driver behind periodical losses of honey bee colonies. The mite requires bees for food and reproduction and, in turn, elicits physiological deficiencies and diseases that compromise bee colony health. The mite nervous system is a target site for existing acaricides. …

The costs and benefits of resistance and tolerance behaviors against Varroa mite (Varroa destructor Anderson and Trueman) in honey bee (Apis mellifera L.)
… different levels of resistance and tolerance to varroa mites were assessed under a variety of treatment combinations to quantify effects of queen pheromone, acaricide treatment, wintering method, ventilation condition and pathogen infection on the costs and benefits associated with mite removal …

Development of a Precision Mite Management Program for the Control of the Ectoparasite Varroa destructor in Hives of Apis mellifera L.
… in CCD is infestation by the ectoparasitic mite, Varroa destructor. Initial efforts to control the mite relied heavily on regular application of miticides without regard to actual mite infestation levels. This approach has led to problems of resistance in the mite and contamination of the …

The effects of environmental factors on honey bee morbidity
… weather, which affect honey bee disease. I use varroa destructor mite and nosema parasite infection levels as measures of honey bee health. Varroa is an important measure of honey bee health because it has been linked to increased overwintering colony losses (USDA 2013). Nosema has also been …

Field and laboratory evaluation of the interactions between pesticides and the gut microbiome in Honey Bees (Apis mellifera)
… a miticide commonly used to treat Varroa mite parasites). Similar to most organisms, the gut microbiome is important for bee health, metabolism, and behavior, however it is not well known how environmental factors like pesticides impact their gut bacterial symbionts. I hypothesized …

Crops, pesticides, and honey bee disease
… correlation between the acres of soybeans with Varroa mite loads and the Deformed Wing Virus. One interesting conclusion of this thesis is that the magnitudes of the correlations are much higher for the interaction of diseases than they are for the magnitudes of the correlations between …
