Drone Choice of Apis Mellifera
Purpose: When a honey bee worker enters the wrong hive, she is promptly thrown out. When a male honey bee drone enters, he is often allowed to stay despite the burden he places on the hive. This research aims to determine how drones decide which colonies to invade, how colonies decide what drones to let in, and how this affects colony health. This work will have applications in honey bee health, disease control, and breeding.

Regenerative Agriculture Demonstration Plots
Purpose: To lay the groundwork for a long-term project measuring the impacts of regenerative (resilient) practices on specialty crops production, we will be growing popcorn as the first crop in this field. The field will be divided in half. One section will be dedicated to conventional practices (tillage, seed treatments, calendar-based pesticide applications) while the other half will be managed using regenerative practices (cover cropping, reduced or no tillage, pest scouting and threshold-based applications of pesticides). Popcorn is the first crop selected because of the capacity of the farm to plant and harvest this crop.

Spider mite Outbreak on Watermelon
Purpose: Pests are a concern for watermelon growers and pesticides are routinary applied in commercial fields to control them. However, overly aggressive insect management could trigger spider mite outbreaks. IPM programs based on thresholds can minimize secondary pest outbreaks. Additionally, rye is used to protect watermelon seedlings from sand blasting damage but growers believe rye can also act as a bride to the crop for spider mites, and they may spray more unnecessary miticides. We hypothesize that intensive insecticide programs and rye cover crop can facilitate spider mite outbreaks, whilst using an IPM program for insect control and no rye would prevent spider mites from outbreak with no miticide applications need.

Determine Optimal Roll Time of Sunnhemp for Cover Crop Based Reduced Tillage (CCRT) Vegetable Systems
Purpose: Conserving soil resources and improving soil health are on the forefront of farmers. Policy makers, and even consumers minds. Reduced tillage is challenging for vegetable production systems due to the need to prepare beds and cultivate. In addition, the short season nature of many vegetable crops often results in nitrogen asynchrony from cover crop decomposition and cash crop uptake. Previous research investigating legumes for reduced tillage systems have had varying results. New cover crop options for reduced tillage vegetable systems production are needed. This project aims to evaluate sunnhemp for a reduced tillage vegetable system. Sunnhemp has shown it can provide large quantities of biomass in addition to its upright stature. These both attributes conducive to a cover crop based reduced tillage system. In addition, sunnhemp can provide up to 134kg/ha of N, which could eliminate or reduce N asynchrony issues observed in cereal rye CCRT systems. This project aims to determine the 1. optimal time to roll sunnhemp, 2. measure N release from cover crop residue and estimate cash crop uptake.
