Description
DK 15541 1 BDK 15541 1 B
Den foreliggende opfindelse angår en insektfælde, især en insektfælde, som lokker insekterne hen på en klæbrig substans inden i fælden.The present invention relates to an insect trap, in particular an insect trap, which lures the insects to a sticky substance inside the trap.
Der kendes insektfælder, som benytter sig af tiltrækkende midler (i 5 det følgende benævnt attraktanter) til at lokke insekterne dertil og fange dem ved hjælp af en klistret eller klæbrig substans i eller på fælden.Insect traps are known which use attractive means (hereinafter referred to as attractants) to lure the insects thereto and trap them by means of a sticky or sticky substance in or on the trap.
Det er konstateret, at effektiviteten af sådanne fælder kan forbedres væsentligt ved at sikre, at attraktanten på kontrolleret måde tvinges 10 ud i fældens umiddelbare nærhed.It has been found that the efficiency of such traps can be significantly improved by ensuring that the attractor is forced out into the immediate vicinity of the trap in a controlled manner.
Den foreliggende opfindelse angår en insektfælde, der omfatter en skorstensdel, en klæbrig substans anbragt inde i skorstensdelen og et reservoir af insektattraktant, hvilken insektfælde er ejendommelig ved, at et varmeorgan er anbragt ved bunden af skorstensdelen, og 15 reservoiret af insektattraktant er anbragt umiddelbart nær og oven over varmeorganet, hvorved varmeorganet fordamper insektattraktanten og danner en konvektionsstrøm af luft, som fører attraktanten ud af skorstenens top og ud i den omgivende atmosfære, og de insekter, som derved af attraktanten lokkes gennem skorstenens top, fanges af den 20 klæbrige substans.The present invention relates to an insect trap comprising a chimney part, a sticky substance arranged inside the chimney part and a reservoir of insect attractant, which insect trap is characterized in that a heating means is arranged at the bottom of the chimney part and the reservoir of insect attractant is placed immediately near and above the heating means, whereby the heating means evaporates the insect attractant and forms a convection stream of air which leads the attractant out of the top of the chimney and into the surrounding atmosphere, and the insects thereby attracted by the attractant through the top of the chimney are trapped by the sticky substance.
Fra FR 374.224 kendes en insektfælde, som omfatter en skorstensdel, en klæbrig substans anbragt inden i skorstensdelen og et reservoir af insektattraktant. I denne kendte insektfælde træder insekterne ind i fælden ved skorstensdelens bund, og ikke ved toppen, medens dampene 25 af insektattraktant imidlertid strømmer ud fra skorstensdelens top og ikke fra dens bund. Ved insektfælden ifølge den kendte teknik lokkes insekterne således ikke ind i skorstensdelen af en strøm af attrak-tantdamp. Endvidere er den kendte insektfælde ikke forsynet med et varmeorgan til at danne en konvektionsstrøm af luft og fordampe 30 insektattraktanten.FR 374.224 discloses an insect trap which comprises a chimney part, a sticky substance placed inside the chimney part and a reservoir of insect attractant. In this known insect trap, the insects enter the trap at the bottom of the chimney part, and not at the top, while the vapors 25 of insect attractant, however, flow out from the top of the chimney part and not from its bottom. Thus, in the prior art insect trap, the insects are not lured into the chimney portion by a stream of attractant vapor. Furthermore, the known insect trap is not provided with a heating means for forming a convection flow of air and evaporating the insect attractant.
Miljømæsssigt er den ved den foreliggende opfindelse tilvejebragte fælde særlig fordelagtig, fordi der ved anvendelse af den opnås en væsentlig reduktion af populationen af flyvende insekter i et rum 2From an environmental point of view, the trap provided by the present invention is particularly advantageous because by using it a significant reduction of the population of flying insects in a room 2 is achieved.

eller et lukket område, uden at det er nødvendigt at anvende et kemisk pesticid.or a closed area without the need to use a chemical pesticide.
Det afgørende træk ved insektfælden ifølge opfindelsen er tilvejebringelsen af en strøm af insektattraktant udgående fra fælden, og 5 det har vist sig, at uden dette træk med tvungen konvektion falder effektiviteten, målt i antal fangne insekter, drastisk. Den tvungne luftstrømning gennem skorstenen opnås som anført ved hjælp af et varmeorgan, som kan drives elektrisk. Reservoiret af insektattrak-tant, som er anbragt nær og oven på varmeorganet, kan være i form af 10 en fast plade eller pille.The decisive feature of the insect trap according to the invention is the provision of a stream of insect attractant emanating from the trap, and it has been found that without this feature of forced convection the efficiency, measured in number of captured insects, decreases drastically. The forced air flow through the chimney is achieved as indicated by means of a heating means which can be electrically operated. The reservoir of insect attractant, which is placed near and on top of the heating means, may be in the form of a solid plate or pellet.
Skorstenen kan være kvadratisk, rektangulær eller cirkulær i tværsnit, selv om andre former om ønsket kan benyttes, f.eks. skål-, plade-, fad- eller bakkeform. Begge ender af skorstenen er åbne eller delvis åbne, så at en luftstrøm kan tvinges igennem.The chimney can be square, rectangular or circular in cross section, although other shapes can be used if desired, e.g. bowl, plate, dish or tray shape. Both ends of the chimney are open or partially open so that an air flow can be forced through.
15 Der kan opnås bedre resultater, hvis den anden ende af skorstenen, der vender bort fra varmeorganet, dvs. den ende, fra hvilken attrak-tanten strømmer ud, for synes med en tilbagetrukken åbning, da flyvende insekter, især stuefluer, har besvær med at undslippe fra en sådan skorsten, når de først er blevet lokket derind. Et tilbagetrukket i 20 det væsentlige konisk formet indgangshul er særlig velegnet. Skorstenens inderside er fortrinsvis lyst farvet, da flyvende insekter foretrækker at flyve ind i et lyst område og ikke et mørkt område, og yderligere er husets yderside fortrinsvis i en varm eller mørk farve, dvs. en brun, rød, sort eller lignende farve, da sådanne farver 25 tiltrækker flyvende insekter.15 Better results can be obtained if the other end of the chimney facing away from the heating means, i.e. the end from which the attractor flows out seems to have a recessed opening, as flying insects, especially houseflies, have difficulty escaping from such a chimney once they have been lured therein. A substantially conically shaped entrance hole is particularly suitable. The inside of the chimney is preferably light colored, as flying insects prefer to fly into a light area and not a dark area, and furthermore, the outside of the house is preferably in a warm or dark color, i.e. a brown, red, black or similar color, as such colors attract flying insects.
Der findes mange attraktanter, som kan anvendes til at lokke flyvende insekter i fælden, f.eks.: 1) 1-(3,4-methylendioxylphenyl)-2-phenyl-1,3-propandiol; 2) 3- cyclohexen-1-carboxylsyre-6-methyl-2-methylpentylester; 30 3) 4,7-methanoinden-6-ol-3a,4,5,6,7,7a-hexahydroformiat; 4) m-toluensyre-2-methoxyethylester; 5) m-toluensyre-2-(2-butoxyethoxy)ethyles ter; 6) tetrahydro-2-(2-propynyloxy)pyran; 3There are many attractants that can be used to lure flying insects into the trap, for example: 1) 1- (3,4-methylenedioxylphenyl) -2-phenyl-1,3-propanediol; 2) 3-cyclohexene-1-carboxylic acid 6-methyl-2-methylpentyl ester; 3) 4,7-methanoinden-6-ol-3a, 4,5,6,7,7a-hexahydroformate; 4) m-toluic acid 2-methoxyethyl ester; 5) m-toluic acid 2- (2-butoxyethoxy) ethyl ester; 6) tetrahydro-2- (2-propynyloxy) pyran; 3

Nogle af de mere effektive attraktanter inden for disse fire klasser er: skatol, indol, ammoniumhydroxid, maltose, acetophenon, benzylal-kohol, pyridin, thymol, dioctylphthalat, glyceroldioleat, orthomonoo-leat, "Jasmin", "Radoxan”, "Herboxan".Some of the more effective attractants within these four classes are: skatole, indole, ammonium hydroxide, maltose, acetophenone, benzyl alcohol, pyridine, thymol, dioctyl phthalate, glycerol dioleate, orthomonoleate, "Jasmine", "Radoxan", "Herboxan" .
5 Til fangning af almindelige stuefluer, Musca dornestica, har "musca-lure" ((Z)-9-tricosen) eller en blanding af denne forbindelse med (Z)-9-heneicosen vist sig at virke meget effektivt i fælden ifølge opfindelsen. Reservoiret for attraktanten kan være i en række forskellige former, f.eks. kan attraktanten være i væskeform i en be-10 holder eller alternativt i fast form, f.eks. dispergeret i cellulose eller i mineralske absorberende stoffer. Et simpelt, effektivt reservoir består af et porøst materiale såsom filterpapir eller klatpapir, som er imprægneret med den ønskede attraktant, og når papirskiver med en diameter på ca. 2,5 cm anvendes, har mængder i området 0,5-150 mg 15 attraktant generelt vist sig at give det ønskede resultat. Stabilisering af attraktanten kan om ønsket opnås ved inkorporering af en antioxidant i reservoiret.For catching common houseflies, Musca dornestica, "musca-lure" ((Z) -9-tricose) or a mixture of this compound with the (Z) -9-heneicose has been found to be very effective in the trap according to the invention. The reservoir of the attractor can be in a number of different forms, e.g. the attractant may be in liquid form in a container or alternatively in solid form, e.g. dispersed in cellulose or in mineral absorbent substances. A simple, efficient reservoir consists of a porous material such as filter paper or blotting paper, which is impregnated with the desired attractant and reaches paper discs with a diameter of approx. 2.5 cm is used, amounts in the range 0.5-150 mg of attractant have generally been found to give the desired result. Stabilization of the attractant can, if desired, be achieved by incorporating an antioxidant into the reservoir.
Den klæbrige substans, som fanger de flyvende insekter, må tydeligvis være en substans, som bibeholder sin klæbrighed i lang tid, og ek-20 sempler på sådanne substanser er opløsninger af gummi, kautsjuk og mineralolie, polybutener og blandinger af voks og harpikser.The tacky substance which traps the flying insects must obviously be a substance which retains its tackiness for a long time, and examples of such substances are solutions of rubber, rubber and mineral oil, polybutenes and mixtures of waxes and resins.
Opfindelsen beskrives nu nærmere under henvisning til tegningen, på hvilken fig. 1 i perspektiv viser en udførelsesform for insektfælden ifølge 25 opfindelsen, fig. 2 i perspektiv en varmeenhed sammen med et attraktantreservoir til den i fig. 1 viste fælde, og fig. 3 i perspektiv en anden udførelsesform for insektfælden ifølge opfindelsen.The invention will now be described in more detail with reference to the drawing, in which fig. 1 shows in perspective an embodiment of the insect trap according to the invention, fig. 2 is a perspective view of a heating unit together with an attractant reservoir for the one shown in FIG. 1, and FIG. 3 is a perspective view of another embodiment of the insect trap according to the invention.
30 Den i fig. 1 og 3 og delvis i fig. 2 viste insektfælde omfatter en elektrisk varmeenhed 1, en cylindrisk skålformet indkapsling eller skorsten 2, et reservoir for insektattraktant 3 og en indre del eller hætte 4, hvorpå den klæbrige substans (ikke vist) til fangning af 5The device shown in FIG. 1 and 3 and partly in fig. 2 comprises an electric heating unit 1, a cylindrical cup-shaped enclosure or chimney 2, a reservoir for insect attractant 3 and an inner part or cap 4, on which the sticky substance (not shown) for catching 5

flyvende insekter, der kommer ind i den skålformede indkapsling eller skorsten 2, er anbragt.flying insects entering the bowl-shaped enclosure or chimney 2 are placed.
Varmeenheden 1 omfatter en elektrisk del (ikke vist) anbragt i en kasse 5, som er forsynet med et antal spalter 6, og over den elektri-5 ske del er anbragt en rist 7, hvorpå reservoiret med insektattraktan-ten 3 er anbragt i form af en rund skive absorberende papir imprægneret med insektattraktanten. Fra toppen af kassen 5 rager to tappe 8 og 9 op til fastholdende af skorstenen 2 på den korrekte plads på varmeenheden.The heating unit 1 comprises an electrical part (not shown) arranged in a box 5, which is provided with a number of slots 6, and above the electrical part a grate 7 is arranged, on which the reservoir with the insect attractant 3 is arranged in the form of a round disc of absorbent paper impregnated with the insect attractant. From the top of the box 5, two pins 8 and 9 protrude up to holding the chimney 2 in the correct place on the heating unit.
10 Skorstenen 2 har som vist i fig. 1 et rektangulært tværsnit, er helt åben i bunden og er i toppen forsynet med en i det væsentlige konisk formet tilbagetrukken indgang 10. En skålformet skorsten er vist i fig. 3. Inden i skorstenen 2 er der en indre del 4, hvorpå den klæbrige substans er anbragt (ikke vist); den indre del kan være fritstå-15 ende, dvs. stå på risten 7, eller være spændt fast eller på anden måde fastgjort til skorstenen 2.The chimney 2 has, as shown in fig. 1 is a rectangular cross-section, is completely open at the bottom and is provided at the top with a substantially conically shaped retracted entrance 10. A cup-shaped chimney is shown in fig. Inside the chimney 2 there is an inner part 4, on which the sticky substance is placed (not shown); the inner part can be free-standing, i.e. stand on the grate 7, or be clamped or otherwise attached to the chimney 2.
Når der er tændt for strømmen, og varmeenheden 1 er varm, frembringes der en tvungen strømning af luft, der passerer gennem spalterne 6, igennem risten 7, henover reservoiret med insektattraktant 3, igennem 20 skorstenen 2 og, ifølge fig. 1, ud gennem hullet 10 til den omgivende atmosfære. Insektattraktantdamp føres med luftstrømmen til dannelse af en strøm af attraktant, som strømmer ud fra toppen af skorstenen 2. Flyvende insekter af den type, som tiltrækkes af den bestemte attraktant, som anvendes i reservoiret, lokkes hen til fælden, flyver 25 ind gennem den tilbagetrukne indgang 10 og fanges af den klæbrige substans (lim:HYVIS-200) på den indre hætte 4. Ved anvendelse af en skålformet modificeret skorsten som vist i fig. 3 frembringes den tvungne luftstrøm af luft, der passerer hen over skålen 4 og ud i den omgivende atmosfære. Damp af insektattraktant føres med luftstrømmen 30 til dannelse af en strøm af attraktantdamp, som strømmer ud fra den øvre ende af skålen. Flyvende insekter af den type, lokkes hen til fælden og fanges af den klæbrige substans på den indre del 4.When the flow is switched on and the heating unit 1 is hot, a forced flow of air is produced, which passes through the slits 6, through the grate 7, across the reservoir with insect attractant 3, through the chimney 2 and, according to fig. 1, out through the hole 10 to the surrounding atmosphere. Insect attractant vapor is carried by the air stream to form a stream of attractant flowing out from the top of the chimney 2. Flying insects of the type attracted to the particular attractant used in the reservoir are lured to the trap, fly 25 in through the retracted inlet 10 and is captured by the sticky substance (glue: HYVIS-200) on the inner cap 4. Using a cup-shaped modified chimney as shown in fig. 3, the forced air flow of air is passed over the bowl 4 and out into the surrounding atmosphere. Vapor of insect attractant is passed with the air stream 30 to form a stream of attractant vapor which flows out from the upper end of the bowl. Flying insects of this type are lured to the trap and caught by the sticky substance on the inner part 4.
I den på tegningen viste udførelsesform er den klæbrige substans placeret på den indre del eller hætte, og det har vist sig hensigts- 6In the embodiment shown in the drawing, the sticky substance is placed on the inner part or cap, and it has been found to be expedient.

mæssigt, at fremstille denne del eller hætte af et éngangsmateriale, så at den, når den er fyldt med døde fluer, kan kasseres og erstattes med en frisk del eller hætte. Delen eller hætten kan være af en hvilken som helst egnet form, om ønsket tilmed i form af en flad 5 plade. I en alternativ udførelsesform, hvor en indre hætte ikke behøves, kan den klæbrige substans anbringes på indersiden af skorstenen, og skorstenen selv kan da være lavet af et éngangsmateriale, så at også den kan kasseres og erstattes med en frisk skorsten, når den er fyldt med fluer.to manufacture this part or cap from a disposable material so that, when filled with dead flies, it can be discarded and replaced with a fresh part or cap. The part or cap can be of any suitable shape, if desired even in the form of a flat plate. In an alternative embodiment, where an inner hood is not needed, the sticky substance can be placed on the inside of the chimney, and the chimney itself can then be made of a disposable material, so that it can also be discarded and replaced with a fresh chimney when it is filled with flies.
10 I andre alternative udføreisesformer kan skorstenen eller den indre hætte, hvis en sådan anvendes, have reservoiret med insektattraktant inkorporeret i sig, enten i hætten eller skorstenen eller anbragt hen over bunden af hætten eller skorstenen, så at det er placeret i nærheden af eller tæt ved varmeenheden.In other alternative embodiments, the chimney or inner cap, if used, may have the insect attractant reservoir incorporated therein, either in the cap or chimney or located over the bottom of the cap or chimney so that it is located near or close to at the heating unit.
15 Insektfælden ifølge opfindelsen kan i praksis sælges som et samlesæt, som kan anvendes sammen med en eksisterende varmeerihed, der er fremstillet med det formål at dræbe andre insekter, f.eks. myg, ved fordampning af et på varmeenheden placeret reservoir af et mygge-pesticid under indvirkning af den af varmeorganet afgivende varme.The insect trap according to the invention can in practice be sold as an assembly set which can be used together with an existing heating unit which is manufactured for the purpose of killing other insects, e.g. mosquito, by evaporating a reservoir of a mosquito pesticide placed on the heating unit under the influence of the heat given off by the heating means.
20 Skorstenen med den klæbrige substans kan sammen med reservoiret med attraktanten let tildannes til at passe til et sådant eksisterende varmeorgan, og et sådant samlesæt til en insektfælde kan omfatte:The chimney with the sticky substance, together with the reservoir with the attractant, can be easily formed to fit such an existing heating means, and such an assembly set for an insect trap may comprise:
En skorstensdel, der er egnet til, at der tvinges en luftstrøm gennem den; 25 et reservoir af insektattraktant, som under indflydelse af luftstrømmen fordamper og føres som en strøm af attraktantdamp fra skorstens-delen til den omgivende atmosfære, og en klæbrig substans, der er placeret på indersiden af skorstensdelen eller på en anden del, som kan placeres inden i skorstensdelen.A chimney part suitable for forcing an air flow through it; 25 a reservoir of insect attractant which, under the influence of the air flow, evaporates and is carried as a stream of attractant vapor from the chimney part to the surrounding atmosphere, and a sticky substance located on the inside of the chimney part or on another part which can be placed before in the chimney section.
30 Dette samlesæt kan omfatte en skorstensdel, der er lavet af tyndt pap eller karton i form af et fladt emne, som kan foldes eller formes til dannelse af skorstensdelen.This assembly set may comprise a chimney part made of thin cardboard or cardboard in the form of a flat blank which can be folded or shaped to form the chimney part.
Som det er antydet ovenfor foretrækker flyvende insekter at flyve ind i et lyst område i modsætning til et mørkt område, og derfor kan 7As indicated above, flying insects prefer to fly into a light area as opposed to a dark area, and therefore 7

skorstenen og den indre hætte fremstilles af et transparent materiale. Af æstetiske grunde er dette imidlertid ikke nogen attraktiv konstruktion, og skorstenen fremstilles fortrinsvis af et opakt materiale med en varm eller mørkfarvet yderside, medens indersiden 5 (såvel som den indre hætte, hvis den er til stede) har en lys farve. Yderligere kan den nederste del af skorstenen være fremstillet af et transparent materiale for at oplyse skorstenens indre. Varmeeriheden kan alternativt enten være fremstillet af et transparent eller et lystfarvet materiale eller omkring og over risten have anbragt en 10 transparent væg, som samvirker med skorstenen og således i virkeligheden udgør en transparent nedre del af skorstenen.the chimney and the inner hood are made of a transparent material. For aesthetic reasons, however, this is not an attractive construction, and the chimney is preferably made of an opaque material with a warm or dark-colored outside, while the inside 5 (as well as the inner hood, if present) have a light color. Additionally, the lower part of the chimney may be made of a transparent material to illuminate the interior of the chimney. The heating unit can alternatively either be made of a transparent or a light-colored material or have a transparent wall arranged around and above the grate, which cooperates with the chimney and thus in fact forms a transparent lower part of the chimney.
Som det også er anført ovenfor, er en betydningsfuld fordel ved den foreliggende fælde den kendsgerning, at den undgår anvendelse af et kemisk pesticid og virker ved, at den klæbrige substans fanger og 15 dræber det flyvende insekt. Det kan i visse tilfælde imidlertid være ønskeligt at benytte et pesticid ud over den klæbrige substans inden i skorstenen, og opfindelsen omfatter ligeledes en fælde indeholdende et sådant pesticid for de fangede flyvende insekter.As also stated above, a significant advantage of the present trap is the fact that it avoids the use of a chemical pesticide and acts by the sticky substance capturing and killing the flying insect. In some cases, however, it may be desirable to use a pesticide in addition to the sticky substance within the chimney, and the invention also encompasses a trap containing such a pesticide for the captured flying insects.
Virkemåden af insektfælden ifølge opfindelsen belyses nærmere i det 20 følgende:The operation of the insect trap according to the invention is further elucidated in the following:
Den i fig. 1 og 2 viste insektfælde placeret i et rum på 28 m^, som holdes ved 23°C (±2°C) og 60% (±5%) relativ fugtighed og ventileres med 3 luftskift pr. time.
