Research Project: Constructing a Pollination and Nut Set Model

Location: Honey Bee Research

2009 Annual Report

1a. Objectives (from AD-416)
Construct a WWW-based program to predict cross-pollination and nut set in almond orchards based on weather conditions, orchard design, and bee foraging population size.

1b. Approach (from AD-416)
A WWW-based model will be constructed that predicts cross-pollination and nut set in almond orchards. The model will be designed as a 3-tier architecture which will include a web presentation layer, a model logic layer, and a data access layer. The web presentation layer will be based on the ASP.NET technology to allow for a rich internet user experience. The data access layer will interface with the MySQL Server database engine, the standard at the Carl Hayden Bee Research Center. The model logic layer will be written in the C# language. Once completed, the model will be able to be run from anyone with an internet connection using standard web browsers. Documents SCA with Crystal River.

3. Progress Report
The structure of WWW-based mathematical model to predict nut set in almond orchards has been defined and programming of the software package is nearly complete. The screens than enable users to enter information and receive predictions in tabular and graphic form also are nearly complete. In addition to predicting nut set from honey bee pollination, we also added components to capture the foraging behavior of Osmia. This will enable growers to simulate conditions where both honey bees and Osmia are present in orchards. An initial version of the program is available at Monitoring of progress on this project is accomplished by conference calls, laboratory meetings, annual reports and presentations to the Almond Board of California. Monitoring of progress on this project is accomplished by conference calls.
