Funded Project
Funding Program: IPM Enhancement Grants
Project Title: Reciprocal Benefits to Cotton Yield and Bee Pollinators in a Cotton/Sorghum Agroecosystem
Project Directors (PDs):
Michael Brewer [1]
Isaac Esquivel [2]
Lead State: TX

Lead Organization: Texas A&M Agrlife Research
Undesignated Funding: $30,000
Start Date: Mar-01-2019

End Date: Feb-28-2020
Pests Involved: Native Bees
Site/Commodity: Cotton
Area of Emphasis: Native Bee Conservation and Cotton Productivity
Summary: The diversity and abundance of native pollinators is important in providing pollination services to a diverse array of crops, many of which receive pollination or unknown pollination benefits from native bees. Under agricultural intensification, as seen in our model cotton agroecosystem where field sizes commonly exceed 300 acres, achieving efficient and productive agricultural land use while conserving biodiversity is an important challenge to U.S. agricultural sustainability. This includes native bee diversity which is a key component of the declining pollinators in the U.S. and which may have been affected by large scale planting of field crops, especially cotton in the southern region. We wish to initiate a joint bee conservation and cotton management concept which may ultimately represent a win-win for bee conservation and cotton insect management. Through agriculturally reasonable stewardship effort, can we conserve native bees (addressing the conservation and IPM charge to address U.S. pollinator decline), which in turn provides reciprocal benefit to cotton (addressing the IPM charge to contribute to agricultural productivity). We propose a seed project to further our initial efforts that support this concept and establish a data base and process that leads to specific management research and guidance for this win bee conservation – win cotton productivity scenario.

Objectives: 1)Effects of landscape structure on the diversity and abundance of native bee pollinators in the cotton agroecosystem.

Objective 1: Identify and record the diversity and abundance of native bee pollinator communities as effected by landscape structure.

2)Evaluate the reciprocal benefits of cotton and native bee pollinators.

Objective 2a: Evaluate the role of cotton as a resource for native pollinators by determining if native bees are actively foraging within the fields.

Objective 2b: Identify benefits of pollination services provided by native bee pollinators on cotton yield.
