Use of alkyl cyclopentanone and phenyl alkanol derivative-containing compositions for repelling blood feeding arthropods and apparatus for determining repellency and attractancy of semiochemicals against and for blood feeding arthropods

A semiochemical field trap for blood feeding arthropods located in a 3-space defined by a vertical "y" axis and horizontal "x" and "z" axes each of which "x" and "z" axis is perpendicular to said "y" axis and each of which "x" and "z" axis is perpendicular to one another comprising:

• (1) upright vertically disposed hollow housing means:
• (A) having arthropod-impenetrable vertical side wall means defining a vertically disposed inner void;
• (B) having an upper terminal end means provided with gas entry means;
• (C) having and piercing said side wall means, at least two horizontally-disposed separate sets of apertures including an aperture set S.sub.1 and an aperture set S.sub.2 with aperture set S.sub.1 being vertically distant from, and substantially adjacent to aperture set S.sub.2 ;
• with a first set of apertures of aperture sets S.sub.1 and S.sub.2 being gas transmission apertures containing gas transmission means and a second set of apertures of aperture sets S.sub.1 and S.sub.2 having first radiation means sealably inserted therethrough;
• (2) horizontally disposed hollow housing means:
• (A) having substantially horizontally disposed arthropod-impenetrable side walls defining horizontally disposed inner void means;
• (B) having oppositely juxtaposed inner and outer open terminal end means;
• the inner terminal end means being circumferentially sealably contiguous with a portion of the outer surface of said vertical side wall means of said upright housing means which portion circumscribes a section of said vertical side wall means including at least one aperture of said S.sub.1 and at least one aperture of said S.sub.2, one of said apertures being a gas transmission aperture containing gas transmission means and the other of said apertures having sealably contained therethrough radiation means;
• (C) having incorporated into the inner structure thereof, arthropod entrapment means;
• and
• (D) having sustainably releasable insect attractant or repellent semiochemical substance means located within (i) said horizontally disposed inner void means or (ii) said gas transmission means;
• (3) gas transmission effecting means for causing conveyance of a gas through said gas entry means, into and through said vertically disposed inner void, through a gas transmission aperture of aperture set S.sub.1 or of aperture set S.sub.2, into and through said horizontally disposed inner void means and into the environment surrounding said field trap;
• (4) second radiation means located within said vertically disposed inner void for conveying insect attracting radiation through substantially each of said gas transmission apertures of aperture set S.sub.1 and/or aperture set S.sub.2 ;
• (5) radiation pulsing means connected to said first radiation means and/or said second radiation means causing said first insect attracting radiation and/or said second insect attracting radiation to have a frequency mimicking insect wing beat and/or insect visual sensing frequencies;
• (6) at least one power supply means associated with said trap at least energizing said first and second radiation means and said radiation pulsing means;
• whereby on engagement of the power supply means with said radiation means and radiation pulsing means and simultaneous activation of said gas transmission effecting means, blood feeding arthropods in the vicinity of said trap are attracted by (i) activated radiation emitted by said first and said second radiation means and (ii) gas emanating from the outer open terminal end means of said horizontally disposed hollow housing means to a location so close to said trap that in the event that an attracting semiochemical in said sustainably releasable substance means is detected and attracts at least one of said arthropods, at least one of said arthropods will enter said horizontally disposed inner void means counter-current to the flow of said emanating gas and will remain permanently entrapped therein.
