Abstract

Arrangement for the targeted guidance of living insects, characterized in that the identification of the insect is guided from a transparent baffle plate (2) to the bottom (16) of a photo box (7) located below and from there into a collection box (19).

Description

Captive flying insects behave differently. Some flutter for a long time, others sit and try to crawl up immediately, others sit and crawl down to find a hiding place or a way out. Individual insects can hardly be moved to take off again after a landing. This makes automatic taking of meaningful and comparable individual photos and counting insects in live traps considerably more difficult, especially if the insects are to remain undamaged.

1. 1. sich nur auf eine bestimmte Fläche einer Fotobox zu setzen, z.B. auf den Boden, um von oben vergleichbare Fotos zu machen,
2. 2. danach geregelt und zügig diese Fläche wieder zu verlassen und in ein Sammelbehältnis zu wechseln, um während einer Messperiode nicht mehrfach gefangen und gezählt zu werden,
3. 3. das Sammelbehältnis erst zum Wunschzeitpunkt geregelt und sicher in die Freiheit zu verlassen und
4. 4. dabei so wenig Schäden wie möglich zu erleiden.

No methods are known to induce live, captive insects to

1. 1. just sit on a certain surface of a photo box, for example on the floor, to take comparable photos from above,
2. 2. then leave this area quickly and in a regulated manner and change to a collection container so that it is not caught and counted several times during a measurement period,
3. 3. The collection container is only regulated and safely released at the desired time and
4. 4. to suffer as little damage as possible.

The arrangement described here meets these requirements. The invention is in the form of a live insect trap using the 1 to 6 explained in more detail. With minimal losses to the life and limb of the insects, it is intended to create the conditions for species identification via photos and counting of all catches. Daily, but then only short-term, for example one-hour operation in the darker twilight hours is planned, since many insects would not survive a longer captivity. The trap can either be switched on in the morning and evening for an hour, for example, or only once a day. Show it:

• 1 the trap in the catch position without a full frame and with a cut through the photo box ( 7 ),
• 2nd the photo box floor opened by inclination ( 16 ) with direction of rotation,
• 3rd the trap when all catches are released and with a full frame ( 30th ),
• 4th Drive and bearing ring of the photo box as well as drives of the photo box floor rotation and its inclination,
• 5 a cut through the photo box ( 7 ) and
• 6 the funnel ( 3rd ) with permanently installed attachments.

1 shows the trap in the overall view without the full frame. With the light source ( 1 ) can attract insects in the dark or at dusk. Through vertical, transparent baffle plates ( 2nd ) braked, they fall through a funnel underneath ( 3rd ) in a cylindrical photo box ( 7 ). The front half of the photo box ( 7 ) is not shown for better illustration. As soon as the invisible camera ( 5 ) the movement of the caught insect in the photo box ( 7 ), multiple processes are triggered. The invisible lighting elements ( 6 ) are switched on, the light source for attracting ( 1 ) is switched off and part of the photo box ( 7 ) is set in rotation. Camera and lighting elements are in 6 to see. The rotating part of the photo box ( 7 ) consists of the side walls ( 8th ), the upper molding ( 9 ) and thrust bearing rings not visible here ( 11 ). Molding ( 9 ) and side walls ( 8th ) the photo box ( 7 ) form an acute angle in which insects crawling upwards get caught without finding the upper central entrance. The rotating photo box part is stored from the outside using the roller bearings that are barely visible here ( 12th ) on the bearing holder ring ( 13 ). It is driven by a motor that is not visible here ( 14 ) and a pressure roller also from the outside. Thrust bearing ring ( 13 ) and funnel ( 3rd ) are firmly attached to the fastening profile ( 15 ) assembled. The caught insects prefer to sit on the still standing floor of the photo box ( 16 ). Near the rotating side walls ( 8th ) there is a fixed, hardly visible wiper wire ( 10th ), which forces those insects to leave the side walls that crawl on them despite the rotation. As soon as the camera not visible here ( 5 ) If the caught insect is in a quiet sitting position, the camera shoots ( 5 ) Photos of him and save them for later identification and documentation. The angle of view of the camera is sufficient to capture the entire visible part of the bottom of the photo box, so that the captured insect sitting there is completely shown on the photos. Then the bottom of the photo box ( 16 ) via the hinge not visible here ( 17th ) folded down and over the engine ( 18th ) set in rotation in this inclined position. The centrifugal force forces the caught insect to leave the seat. Then the rotation of the bottom of the photo box ( 16 ) stopped, the photo box floor ( 16 ) folded back up into the horizontal and the light source ( 1 ) switched on again.

The caught insect is in the meantime inside the collection container ( 19th ). This consists of gauze side walls ( 20 ), an upper funnel-shaped molded part ( 21 ) and a separate floor ( 26 ). The diameter of the collection container ( 19th ) increases towards the bottom. Here also form part ( 21 ) and side walls ( 20 ) an acute angle, so that trapped and crawling insects cannot find the middle-top entrance.

At the end of the fishing period, the lower end of the collection container ( 22 ) on the threaded spindle ( 24th ) via the threaded nut ( 23 ) moved up. To do this, a motor that is not visible here ( 32 ) the threaded spindle ( 24th ) turned. A guide rod ( 25th ) prevents the end ring from turning away ( 22 ) while lifting.

Then the bottom of the collecting container ( 26 ) around the axis ( 27 ) rotated by 180 °.

Before the next measurement period, the network end ring ( 22 ) via threaded spindle ( 24th ) and threaded nut ( 23 ) moved down again so that the collecting container is insect-tight again.

2nd shows as a detail the bottom of the photo box that was tilted down to release the caught insect ( 16 ). The motor ( 18th ) creates a rotation of the soil ( 16 ), the direction of which is indicated by an arrow.

3rd shows the entire trap together with the surrounding full frame ( 30th ) in the position that allows all previously caught insects to escape. The net end ring of the collecting container ( 22 ) is with the threaded nut ( 23 ) on the threaded spindle ( 24th ) have been moved up. The spindle ( 24th ) by the engine ( 32 ) turned. Both the engine ( 32 ) as well as the fastening profile ( 15 ) are about the crossbar ( 29 ) firmly on the full frame ( 30th ) assembled. The guide rod ( 25th ) made sure that the net end ring ( 22 ) does not turn away. In addition, the retaining ring ( 31 ) to recognize the molded part ( 21 ) firmly with the fastening profile ( 15 ) connects. The retaining ring ( 31 ) allows the cylindrical photo box sides to rotate freely through a small gap ( 8th ). The gauze sidewalls of the collection container ( 20 ) have turned upwards and tightened again, so that the previously at an angle from the molded part ( 21 ) and side walls ( 20 ) insects can now crawl upwards and fly away. The bottom of the collecting container ( 26 ) is shown in an intermediate position. It is driven by the engine ( 35 ) on the axis ( 27 ) rotated by 180 °, so that insects previously stubbornly sitting on the top of the floor also remain on the underside of the floor during the next measurement period ( 26 ) and can fly at any time.

4th shows storage and drives of photo box rotation and the movements of the photo box floor ( 16 ). On the bearing ring ( 13 ) are various roller bearings ( 12th ) mounted, which from the outside smoothly rotates the photo box ( 7 ) enable. Several bearings also prevent the photo box from being lowered ( 7 ) during rotation. The rotation is over the motor ( 14 ) which presses against the photo box via a pressure cylinder. The folding mechanism of the bottom of the photo box to be triggered to transfer a caught insect ( 16 ) is exemplified about the engine ( 33 ) and the linkage ( 34 ) operated. The photo box floor folds on one arm ( 36 ) downward. The arm is over the hinge ( 17th ) on the fastening profile ( 15 ) assembled. After folding down, the engine ( 18th ) are switched on to let the bottom of the photo box rotate so that the insect sitting on it flies outwards due to the centrifugal force generated.

5 shows a section through the rotatable part of the photo box ( 7 ), consisting of the side walls ( 8th ), the funnel-shaped part ( 9 ) and the two bearing pressure rings ( 11 ). The upper bearing pressure ring also has a horizontal bearing pressure ring at the top, which prevents the container from sliding down during rotation.

6 shows the funnel ( 3rd ) and the parts connected to it. The wiper wire ( 10th ) is like the camera ( 5 ) and the lighting elements ( 6 ) on the funnel disc ( 4th ) mounted, which in turn is firmly attached to the funnel.

The trap is controlled by an invisible processor that e.g. can be protected from rain in the lid. An invisible twilight switch can be used to activate the trap and a timer to deactivate it. The photos taken can be automatically transmitted to a server via a radio link, where catches are identified and the data of several traps are managed and stored.
