Abstract
A system for achieving a controlled low emission rate of small volumes of liquid solutions for pest and insect management and other applications. The system has a sealed liquid solution reservoir having an outlet port, a self-powered fluid delivery micropump, and a collector for receiving a liquid solution from the sealed liquid solution reservoir. The liquid solution reservoir has a small volume capacity in the range of 1-100 mL. The micropump is a fluid transfer device capable of delivering 1-1000 microliters/hour of liquid solution. The collector has a low emission rate in the range of 0.1-2000 mg/day. The micropump and the sealed liquid solution reservoir may be contained in a single assembly. Also the entire structure of the system may be located in a single container that may be attached to a support structure. The system also allows a multicomponent mixture in the reservoir to be delivered to a collector such as a blotter that allows the different chemical agents to emanate therefrom at a constant ratio throughout the term of the operation.
