Our invention is directed to a semiochemical field trap for blood feeding arthropods which has the capability of causing determination of repellency and attractancy of semiochemicals against and for blood feeding arthropods. The field trap comprises an upright vertically disposed hollow housing having arthropod-impenetrable vertical side wall, at least two horizontally-disposed separate sets of apertures, being gas transmission apertures containing a gas transmission means (e.g., a polyethylene tube) or having first radiation means sealably inserted therethrough (for example, a light emitting diode or a laser diode), a horizontally disposed hollow housing, a gas transmission effecting means for causing conveyance of a gas (such as air or carbon dioxide) through the gas entry means a second radiation means for conveying insect attracting radiation, a radiation pulsing means connected to the first radiation means and/or said second radiation means causing the first insect attracting radiation and/or the second insect attracting radiation to have a frequency mimicking insect wing beat and/or insect visual sensing frequencies, and at least one power supply means associated with the trap at least energizing the first and second radiation means and the radiation pulsing means. |
