Abstract

The invention relates to an insect trap which is especially intended for catching and/or rendering harmless flying insects and/or harmful insects. The insect trap (10), in a first embodiment, has a planar or curved, light surface (12) and at least one dark contrast spot (16) disposed inside said surface. The insect trap (10), in a second embodiment, has a diffuser surface (14) for producing a weak air current (22) that emanates from said surface. Both embodiments can be combined as required to increase the effectiveness of the trap. The insect trap (10) is further provided with devices for keeping, catching and/or eliminating trapped insects (42) on a surface of the trap and/or in a cavity (20) arranged therein. Insect traps of the above mentioned type are used in pest control indoors and outdoors and for detecting an insect density (monitoring).

To this end a further tube is provided around the cylindrical tube. The insects are sucked into a space between the two coaxial tubes. 5 With the known types of traps carbon dioxide is used, since this gas is recognized by insects as what is exhaled by humans and animals and therefore attracts them. 10 The effectiveness and efficiency of the hitherto known traps is however mainly limited because they cannot be fully effective to neutralize all the insects in a given room or space. In addition the traps that emit carbon dioxide are relatively expensive to make and 15 operate. The present invention provides an insect trap, in particular for flying and/or pest insects, comprising: a planar or curved light surface region, 20 an emanating surface emitting a weak air-current passing our through the emanating surface, and means for holding, trapping and/or killing attracted insects on a surface of the insect trap and/or in its hollow interior, 25 wherein the colour of the emanating surface is light, and at least one dark contrasting surface region is located within the emanating surface. Tests with embodiments of the above-described 30 insect trap have shown that a light surface region with a dark spot in it, for example in its center, is very attractive for certain insects and draws them. Hitherto it has only been recognized that dark objects are capable of attracting certain types of insects. The invention 35 improves on this by providing a dark contrast region on a light background. Tests have also shown the surprising effect that a -2 2162140_1 (GHMatters) weak and uniform air stream spread over a large surface is attractive for many insects and draws them. This can be explained in that the weak air stream over a large surface area is like the warm air flow of a human or animal body 5 that is in particular recognized by gnats (aedes aegypti) and blood-sucking insects and that draws them. According to an embodiment of the invention at least the light surface region or parts of it are covered 10 with glue and/or an insecticide. In addition at least the dark contrast surface region can be covered with glue and/or an insecticide, so that the upper -3 2152140_1 (GHMatlers) 296 iCTI&2003IOO 4 1~ 62 'rnu-of WO 2004M04358 oirface of the txap fUnctioZna to hold tkM attracted inoeots, A~lternatively the japectf oan be killed by Contact with t1he traV oufRc!.
