Project Type: Specific Cooperative Agreement
Start Date: Sep 9, 2013
End Date: Sep 8, 2018
The objective of this cooperative research is to profile certain pesticide residues from foliar and seed applications when applied to corn, cotton, and soybeans to ultimately develop better management decisions to minimize exposure to honey bees. New objective will add the ability to monitor the activity and behavior of honey bee colonies exposed to sub-lethal levels of neonicotinoid insecticide using radio-frequency identification (RFID). In addition, funds will also be used to investigate the proportion of plants visited by honey bees as crop or non-crop using pollen traps to taxonomically identify the forage host.
Pesticide Trials with Soybean, Corn, and Cotton: The foliar applied treatments will include a non-treated control and various commonly labeled pesticides, including insecticides and fungicides, at recommended rates. Plant tissue samples will be collected from various plant structures to determine if residues are indeed present. These trials will located on the University of Arkansas Experiment Station property. Bees: Managed hives will be placed in proximity to these crops. Samples of bees, pollen loads, and stored pollen will be collected and analyzed for pesticide residues. Taxonomic identity of collected pollen will be determined. In addition, colony health of 16 managed hives will be monitored throughout the growing season using methods described at www.colonymonitoring.com. Plant Tissue and Bee Insecticide Analysis: All samples will be analyzed at the USDA, AMS, National Science Laboratory, Gastonia, NC.
