Incorporating a nectar-based pesticide module into BeeHave, an agent-based model of honey-bee population dynamics

Honey bees are important pollinators for many agricultural food crops, and the response of honey bee colonies to pesticides must be included in pesticide risk assessments. However, honey bee colony dynamics are driven by complex interactions of ecological, physiological, and chemical factors. Such complexity lends itself to a modeling approach to characterize colony responses to pesticides. The NetLogo-based model BeeHave is a detailed model of honey bee colony dynamics. One recently released version of this model (BeeHave_BeeMap_PEEM) considers pesticide exposure via the pollen ingestion pathway. However, nectar ingestion is also a critical exposure pathway, and an exposure module via nectar is needed for this model. We adapted BeeHave to include a nectar-based pesticide exposure module. Exposure is proportional to consumption of nectar and honey based on the energetic needs (kJ) of bee cohorts, and dose depends on the pesticide concentrations of nectar and honey. We assessed the model..., , # Incorporating a nectar-based pesticide module into BeeHave, an agent-based model of honey-bee population dynamics

## Description of the data and file structure

The supplemental materials are stored in 4 files, including 3 zipped files (i.e., compressed folders stored with a \".zip\" extension) and a .txt file. The compressed folders each contain multiple files once extracted, and each compressed folder has its own ReadMe file providing information on the content of the files in the folder.

* Here is a summary of each of the 4 supplemental files:
