Research Project: Longitudinal Studies to Determine the Causes of Honey Bee Loss

Location: Exotic and Invasive Weeds Research

Project Number: 2030-21000-001-00-D
Project Type: In-House Appropriated

Start Date: Mar 1, 2015
End Date: Feb 28, 2019

Objective:
Pollinators, such as honey bees and other insects, are critical components of both natural ecosystems and agroecosystems, ensuring the production of many agronomic crops. Objective 1: Employing long-term, longitudinal studies of honey bee survivorship under current management conditions for honey bees used as pollinators and honey producers, elucidate honey bee forage needs and causes of mortality to serve as the basis for best management practices for pollination of specialty crops such as almond.

Approach:
Honey bees are the main pollinators of crops in the United States and worldwide.Losses of honey bees due to a variety of factors are unsustainable at the current levels of over 30 percent. To mitigate these losses, it is necessary to determine their causal factors; however, long-term baseline data for colony survivorship is not available that can be used to parse the relative importance of suspected factors. It is therefore crucial to develop such a methodology, particularly as part of long-term longitudinal studies of spatial and temporal changes in bee populations exposed to a number of abiotic and biotic stresses and management practices. These longitudinal studies may incorporate research on pesticide, pathogen/pest, and nutrition/forage or other bee health effects, using hives that are stationary as well as those that follow pollination service migratory routes. The proposed longitudinal studies support ARS National Program on Production (NP305) Action Plan research objectives; Component 2: Bee Health; Problem Statements 2A: Bee Management—Improving Bee Nutrition and Performance, 2B: Bee Health—Mitigating the Impacts of Pathogens, Pests, and Pesticides, and 2C: Maximizing Bee Pollination and Quantifying Bee Forage Requirements of the Action Plan.
