Introduction
My current research explores the exposure and impact of pesticide mixtures in ground-nesting bees, using the hoary squash bee (Peponapis pruinosa) and the common eastern bumble bee (Bombus impatiens) as agriculturally relevant model species. I have a broad interest in sustainable food production, with a research focus at the interface of pollinator conservation and crop protection.

Exposure to pesticides is a major threat to bumblebee (Bombus spp.) health. In temperate regions, queens of many bumblebee species hibernate underground for several months, putting them at potentially high risk of exposure to soil contaminants. The extent to which bumblebees are exposed to residues in agricultural soils during hibernation is curren...

Fungicides account for more than 35% of the global pesticide market and their use is predicted to increase in the future. While fungicides are commonly applied during bloom when bees are likely foraging on crops, whether real-world exposure to these chemicals – alone or in combination with other stressors – constitutes a threat to the health of bee...
Article

Water is essential for honey bees (Apis mellifera L.), but contaminated sources of water in agricultural environments represent a risk of exposure to potentially harmful contaminants. Providing clean water to honey bees could be an efficient and cost-effective measure for beekeepers to reduce bee mortality associated with pesticides and improve the...

For non-profit organizations relying on volunteers to operate, investigations into the motivations of volunteerism are critical to attract new volunteers and to support the current ones. This study looked at volunteerism in the not-for-profit project The SEED in Ontario, Canada, which is looking to address food insecurity through a new social enter...
Article
Profitability of biofuel production from microalgae is difficult to achieve but co-locating production with wastewater treatment plants is a possible avenue help to reduce costs. A microalgae culturing project was conducted using wastewater from an industrial park to obtain valuable metabolites from the biomass to eventually use them locally. Diffe...
Article
The ectoparasitic mite Varroa destructor Anderson & Trueman is a major pest of the honey bee Apis mellifera L. (Hymenoptera: Apidae) and its control is one of the most important challenges that beekeepers have to face. In this study, we investigated the use of the predatory mite Stratiolaelaps scimitus (Womersley) for the biological control of varr...

Full-text available
The biocontrol of the honey bee ectoparasite Varroa destructor is an underexploited but promising avenue that would benefit from being integrated in a Varroa management program. Our study aimed to investigate the potential of the predatory mite Stratiolaelaps scimitus to control Varroa infestations in honey bees. Tests on safety and predation were...
