Abstract

An insect trap (100) is disclosed which has insect retention means (300) for preventing escape of insects which enter an effective zone of said insect retention means (300) and insect attractant means (200) for attracting insects from a selected group of insects to within said effective zone of said insect retention means (300). The attractant means include at least one variable infra-red radiation emission means (2, 4) adapted to emit variable infra-red radiation. The arrangement is such that insects from the selected group which are outside the trap (100) can detect the variable infra-red radiation and are attracted to an area within the effective zone of the insect retention means (300). A method of attracting insects from a selected group of insects to a predetermined location is also disclosed.

Claims

1. An insect trap including insect retention means provided within a body of the trap for preventing escape of insects which enter an effective zone of said insect retention means, the insect retention means including a fan which directs airflow through a porous bag, the trap further including insect attractant means for attracting insects from a selected group of insects to within said effective zone of said insect retention means, wherein said insect attractant means include at least one variable infra-red radiation emission means adapted to emit variable infra-red radiation, the variable infra-red emission means provided adjacent the fan, the insect attractant means including at least one flickering or pulsing light source directed towards the fan and the variable infra-red emission means, the arrangement being such that insects from said selected group which are outside the trap can detect said variable infra-red radiation, movement of the fan, and reflection of light from the at least one light source from the fan and the variable infra-red radiation emission means, and are thereby attracted to an area within said effective zone of said insect retention means.

2. The insect trap of claim 1 wherein at least one of said infra-red radiation emission means includes a heating means.

3. The insect trap of claim 2 wherein said heating means varies in temperature.

4. The insect trap of claim 1 wherein said at least one variable infra-red emission means includes a plurality of sources of infra-red radiation and said trap includes control means adapted to operate said plurality of sources of infra-red radiation sequentially, randomly and/or pseudo-randomly.

5. The insect trap of claim 4 wherein said at least one light source includes at least one source of substantially ultraviolet light.

6. The insect trap of claim 1 wherein said infra-red emission means is located inside a body of the trap and said infra-red emission is directed outside the trap by a plurality of fiber optic filaments.

7. The insect trap of claim 1 wherein at least a section of a body of said trap may be transparent or translucent to improve the visibility of said attractant means.

8. The insect trap of claim 1 wherein said selected group of insects includes at least one member of the mosquito family.

9. A method of attracting insects from a selected group of insects to an effective zone of an insect retention means of an insect trap, wherein the insect retention means include a fan which directs air flow through a porous bag, the method including the steps of:

i) locating at least one variable infra-red emission means adjacent said fan;

ii) directing at least one pulsing or flickering light source at the fan and the variable infra-red emission means; and

iii) operating said at least one infra-red emission means in a manner which causes variable emission of infra-red radiation wherein

iv) the location of the at least one variable infra-red emission means and the fan is such that reflection of light from said at least one light source from said fan and said variable infra-red radiation emission means is detectable by insects outside the trap, and thereby attracts insects to an area within said effective zone of said insect retention means.

10. The method of claim 9 wherein said step i) includes locating at least one heating element adjacent said fan and said step ii) includes varying a temperature of said heating element.

11. The method of claim 9 wherein said step i) includes providing a plurality of sources of infra-red radiation and said step ii) includes using a control means to operate said plurality of sources of infra-red radiation sequentially, randomly and/or pseudo-randomly.

12. The method of claim 9 wherein said selected group of insects includes at least one member of the mosquito family.

13. A mosquito trap including insect retention means for preventing escape of members of one or more selected species of mosquito which enter an effective zone of said insect retention means and insect attractant means for attracting members of said one or more selected species of mosquito to within said effective zone of said insect retention means, wherein said insect attractant means includes;

at least one variable infra-red radiation emission means adapted to emit variable infrared radiation;

at least one source of visible and/or ultraviolet light;

at least one reflective surface within or adjacent said effective zone positioned to reflect light from said light source; and

at least one fan positioned to reflect light from said source of visible and/or ultraviolet light;

the arrangement being such that members of said one or more species of mosquito which are outside the trap can detect said variable infra-red radiation and said light reflected from said reflective surface and said fan, and are attracted to an area within said effective zone of said insect retention means.
