Abstract
Abstract Apparatus for dispersing a gaseous or vaporized pheromone trail into the atmosphere under determined conditions comprises first container (10) in which a pheromone source (22) is located. Means (12) to create and upward draught is provided surmounting the first container (10). Flying insects lured by the trail enter the means 12 and into the first container (10) then to a second container (9) out of which they cannot escape. Alternatively, the insects land on a sticky insecticide from which they cannot escape.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
230 words
Apparatus for dispersing a gaseous or vaporized pheromone into the atmosphere, comprising a first housing within which at least one pheromone-releasing source holding means is located, the housing having at its top and outlet, upward-draft creating means provided on said first housing which has adjacent to or below the, or each holding means, air introducing means, wherein the upward-draft creating means is mounted over the outlet, and comprises a series of annular vanes, the uppermost and lowermost of which are parallel and of frusto-conical shape or substantially of frusto-conical shape, a central aperture in each said vane, a common axis about which the vanes are centered and arranged in predetermined vertical spaced relationship, a plurality of supports parallel to and radially spaced from said axis, the lowermost of said vanes converging inwardly toward the next upper vane which is usually horizontal and planar in a diameter towards the common axis but may have a frusto-conical profile of shallower angle than the uppermost and lowermost vane forming a venturi, a device of aerodynamic shape mounted co-axially with the vanes and located between the upper two vanes, the device masking but not closing the central apertures in said vanes, and having upper and lower cone-like or dish-shaped air-deflecting walls arranged base-to-base about said common axis, the upper wall of the device being parallel or substantially parallel to the uppermost and lowermost vanes.
Claim 2
Dependent Claim
