Abstract: An integrated reservoir and controlled release matrix system (1) for the controlled release of insect semiochemicals is described. The system includes a reservoir (2) possessing a volume chamber and sealed vent opening (5) at one end. Extending from the opposite end of the reservoir chamber is a hollow needle-like conduit (7) which is open to the reservoir chamber at one end. The conduit protrudes or extends from the reservoir and impregnates a release matrix (3), effectively connecting the reservoir with the release matrix. The conduit may be variously formed with: a) an opening at the reservoir end which is open to the reservoir chamber and only one opening at the opposing end protruding into the release matrix; or b) multiple perforations along its length accompanying the end opening into the release matrix; or c) multiple lengthwise perforations without an end opening into the release matrix. The release matrix is also variously formed of elongated cubic or spherical geometry.
