DESCRIPTION:
BRIEF SUMMARY
This invention relates to apparatus for dispersing a gas or vapor into the atmosphere under determined conditions.
Certain hormones, called pheromones, have been developed as an attractant for various flying insects, or insects which pass through a flying stage. There are also other attractants available either of similar scent to the pheromones, or of similar scent to a popular food source for particular species of flying insects. It is proposed to lure these flying insects by laying airborne trails of these pheromones or attractants, and to entrap and subsequently kill any flying insects so attracted. Hereinafter in the specification and claims the word "pheromone" is used to include also any other attractant available for the purposes stated, and also to include natural pheromones released by actual insects held in captivity.
The object of the present invention is to provide an apparatus for dispersing an airborne trail of a gaseous or vaporized pheromone into the atmosphere.
SUMMARY OF THE INVENTION
According to the present invention, there is provided an 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 an outlet, upward-draft creating means provided on said first housing, which has, adjacent to or below 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 towards the next upper vane which is usually horizontal and planar in a direction towards the common axis to form a venturi at their inner peripheries, but may have a frusto conical profile of a shallower angle than the uppermost and lowermost vanes, 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.
Preferably also, the first housing is an upright tube, the opening at the lower periphery of which is closable by a web provided in a second housing submounting the first housing, the air-introducing means being one or more air bleed holes provided in said web. Each pheromone source holding means is provided on the top of the web to extend into the first housing. A skirt extends peripherally around the first housing below the draft creating means and on top of which skirt a sticky insecticide is located to entrap and kill insects.
Preferably further, the second housing has a minor upper tubular portion integral with a major lower hollow frusto-conical portion in the bottom of the walls of which one or more cut-outs are provided.
Alternatively, the second housing is open-topped and may be closable by a lid centrally of which is provided the outlet over which the first housing with its means to create an upward draft is mounted, a tubular portion of the lid having the web thereacross being provided for engagement with said first housing and to hold said lid to said first housing. The second housing is of inverted truncated conical shape over the lower periphery of which a collecting bag is securable.
