This senior project discusses the analysis, evaluation and business strategy for a newly designed Husk Fly Trap from Ag Chem Wholesalers located in Yuba City, California. This prototype is designed to hold 2 to 3 weeks’ worth of Ammonium Carbonate and alleviate the hassle of monitoring the Walnut Husk Fly. This system is cost affective, able to hold the same amount, or 2 – 3 weeks, of Ammonium Carbonate as a “supercharged” trap. The Prototype Trap is easier to handle by not having to replace blown away traps or ruined sticky cards saving Pest Control Advisors time and allowing them to make more money by covering more acres with that saved time. Recommendations are to paint it yellow and to design a permanent mounting system, rather than a hook that may allow the monitoring sticky card to blow off the hook in high winds. Additionally, studying the effectiveness of the trap against a commercial trap and possibly replacing zip ties that hold on the cheesecloth on the ends of the trap with open PVC pipe covers or open PVC pipe covers with a screen in the opening.
