Methods and systems for biological control of pests and pest-borne diseases, such as in agriculture, include vapor delivery systems with (a) a reservoir for holding the volatile compound(s), typically in liquid form, to be released into the atmosphere, (b) a means of supplying the reservoir with volatile compound(s), (c) one or more passive flow control nozzles attached to the reservoir, wherein each nozzle is fitted with a permeable polymeric membrane through which the volatile compound permeates and is emitted from the outer membrane surface into the atmosphere, and wherein the individual nozzles are adapted to deliver a specific predetermined release rate for each intended application, and (d) strategic deployment of nozzles (i.e., number, location, spacing, height, etc.) to achieve performance requirements for intended applications ranging from a single plant to large fields for specific ambient conditions.
