Description

Margborer er en art av barkbiller som utvilsomt hører til blant de mest alvorlige skadeinsekter på furu i store deler av verden. Svermetiden for margborere er tidlig om våren. De svermende billene angriper ferskt furutømmer. Av og til angriper de også levende furutrær. Hos begge arter borer først hunnen seg inn i barken og begynner å lage morgang i bastlaget. Billenes sverming er sterkt avhengig av været. Den begynner Weevils are a species of bark beetle that is undoubtedly one of the most serious pests of pine in large parts of the world. Swarming time for marten borers is early spring. The swarming beetles attack fresh pine timber. Occasionally they also attack living pine trees. In both species, the female first burrows into the bark and begins to make morgang in the bast layer. The beetles' swarming is strongly dependent on the weather. It begins

når temperaturen overstiger 11-12°C. Alt efter årlig og geografisk variasjon skjer dette i tidsrommet tidlig i april til tidlig i juni på den nordlige halvkule. Normalt er svermingen over i løpet av få uker, og senere flyaktiviteter vet man lite om. when the temperature exceeds 11-12°C. Depending on annual and geographical variation, this happens in the period from early April to early June in the northern hemisphere. Normally, the swarm is over within a few weeks, and little is known about later flight activities.

Det har vært antatt at den luktbetingede tiltrekning av margboreren Tomicus piniperda til vertstreet skyldes monoterpen-hydrokarbonene, f.eks. terpinolen og a-pinen, som inneholdes i den flytende harpiks i pinus sylvestris. It has been assumed that the odor-induced attraction of the pith borer Tomicus piniperda to the host tree is due to the monoterpene hydrocarbons, e.g. the terpinol and a-pine, which are contained in the liquid resin of pinus sylvestris.

Vertsvalg og kolonisering for formering finner sted på en tid og efter et mønster som ikke faller sammen med en ferromon-regulert masseansamling som iakttas hos barkbiller som koloni-serer vertstrær som reaksjon på insektfrembragte lokke-stoffer (Vité, J.P., Francke, W.: Chemie in uns. Zeit 19, 11 (1985)), og heller ikke i overensstemmelse med den kjede av begivenheter ved vertsvalg som iakttas hos insekter som angriper uskadede vertsplanter. Istedet forekommer det massive sverminger tidlig hver vår, hvilket fører til øyeblikkelig og samtidig kolonisering av et egnet yngelmateriale, uten at det synes å være noen sammenheng med tidligere vellykkede billeangrép. Hittil foretatte undersøkelser hverken beviser (Schonherr, J.: Z.ang.Ent. 71, 410 (1972)) eller antyder (Långstrom, B., et al.: Z.ang.Ent. 99, 174 (1985) at det forekommer ferromonkomponenter ved T-piniperda ansamling, mens den åpenbare tiltrekkende evne hos uskadede furustykker overfor en svermende bille-populasjon, tyder på at gjenkjennelsen hovedsakelig har sammenheng med vertslukter, sannsynligvis bestanddeler i flytende furuharpiks. Host selection and colonization for reproduction take place at a time and in a pattern that does not coincide with a pheromone-regulated mass accumulation observed in bark beetles colonizing host trees in response to insect-produced attractants (Vité, J.P., Francke, W.: Chemie in uns. Zeit 19, 11 (1985)), and also not in accordance with the host-selection chain of events observed in insects attacking undamaged host plants. Instead, massive swarms occur early every spring, which leads to immediate and simultaneous colonization of a suitable brood material, without there seeming to be any connection with previously successful beetle attacks. Investigations carried out so far neither prove (Schonherr, J.: Z.ang.Ent. 71, 410 (1972)) nor suggest (Långstrom, B., et al.: Z.ang.Ent. 99, 174 (1985)) that it pheromone components occur in T-piniperda accumulation, while the obvious attractiveness of undamaged pine pieces to a swarming beetle population suggests that the recognition is mainly related to host odors, probably components of liquid pine resin.

Efter nærmere vurdering fant vi at de harpikslukter som kommer fra trær, kvister o.l. neppe kan være årsaken til den umiddelbare kolonisering av stubber og tømmerstokker, med mindre de vertsspesifikke terpener suppleres med andre stoffer som friske furutrær mangler. Ved de tallrike undersøkelser som de siste 30 år har vært foretatt med hensyn til det valg av vert som T-piniperda gjør (Oksanen, H., et al.: Contrib. Boyce Thompson Inst. 24, 299 (1970)) har man ikke tatt i betraktning en mekanisme som er karakteristisk for den luktbetingede orientering hos visse ikke-aggresive barkbiller som for sin formering er avhengig av et meget egnet vertsmateriale. After further assessment, we found that the resin smells coming from trees, twigs etc. can hardly be the cause of the immediate colonization of stumps and logs, unless the host-specific terpenes are supplemented with other substances that fresh pine trees lack. In the numerous investigations that have been carried out in the last 30 years with regard to the choice of host that T-piniperda makes (Oksanen, H., et al.: Contrib. Boyce Thompson Inst. 24, 299 (1970)) one has not taking into account a mechanism that is characteristic of the odor-based orientation of certain non-aggressive bark beetles that depend on a very suitable host material for their reproduction.

Når trær er syke eller svekket, eller i stubber og tømmer-stokker, finner det sted en anaerob fermentering som fører til dannelse av etanol (Granham, K., Can. J. Zool, 46, 905 (1968)). Vi fant at det var mulig at denne etanol var årsaken til at margboreren går til angrep på et vertstre. When trees are diseased or weakened, or in stumps and logs, anaerobic fermentation takes place leading to the formation of ethanol (Granham, K., Can. J. Zool, 46, 905 (1968)). We found that it was possible that this ethanol was causing the pith borer to attack a host tree.

For å undersøke denne hypotese under feltbetingelser ble konusfeller (Rochling-Flachtrichterfallen) anbragt 8 meter fra hverandre i furuskoger med endemiske populasjoner av T-piniperda. I fellene ble innført alternativt en blanding av terpinolen og racemisk a-pinen i et forhold på 1:1, og en blanding av terpinolen, a-pinen og etanol i et forhold på 1:1:3, og disse blandinger ble frigjort fra 3 x 5 cm porøse puter innesluttet i en polyetylen dispenserpose (0,05 ml lav-tetthet PE). Antall biller (x) som ble fanget pr. behandling ble omregnet med formelen V x+0,5' (Oksanen, se ovenfor) og underkastet varians-analyse. Signifikante forskjeller ved forsøkené ble påvist med 0,05 sannsynlighetsnivået under anvendelse av Duncan's "multiple range test" (Roelofs, W. U., Cardé, R.T.: Ann. Rev. Entomol. To investigate this hypothesis under field conditions, cone traps (Rochling-Flachtrichterfallen) were placed 8 meters apart in pine forests with endemic populations of T-piniperda. Alternatively, a mixture of terpinolene and racemic α-pinene in a ratio of 1:1, and a mixture of terpinolene, α-pinene and ethanol in a ratio of 1:1:3 were introduced into the traps, and these mixtures were released from 3 x 5 cm porous pads enclosed in a polyethylene dispenser bag (0.05 ml low-density PE). Number of beetles (x) that were caught per treatment was converted with the formula V x+0.5' (Oxane, see above) and subjected to variance analysis. Significant differences between trials were detected at the 0.05 probability level using Duncan's multiple range test (Roelofs, W.U., Cardé, R.T.: Ann. Rev. Entomol.

22, 377 (1977). 22, 377 (1977).

De oppnådde resultater, som er illustrert i den nedenstående tabell, støtter fullt ut den hypotese at fenomenet med øyeblikkelig kolonisering av furustubber og -tømmerstokker, spesielt av T-piniperda hunnbiller, i det minste delvis skyldes en synergistisk virkning mellom primært (monoterpener) og sekundært (etanol) dannede vertslukter som kommer fra furu-vertstrær med redusert vekst. Det er mulig at kjønnsbetingedé ferromoner har innvirkning på forholdet mellom hann- og hunnbiller som fanges. The results obtained, which are illustrated in the table below, fully support the hypothesis that the phenomenon of immediate colonization of pine stumps and logs, especially by T-piniperda female beetles, is at least partially due to a synergistic action between primary (monoterpenes) and secondary (ethanol) formed host odors coming from pine host trees with reduced growth. It is possible that sex-specific pheromones have an impact on the ratio between male and female beetles that are captured.

Forholdet mellom komponentene i lokkestoffet kan varieres, men det er vesentlig at de ønskede lokkestoffer er til stede så lenge som mulig for å oppnå mest mulig langvarig virkning. Foruten terpinolen og a-pinen kan også andre terpener som forekommer i furu, benyttes enten istedenfor eller i tillegg til terpinolen og a-pinen. Eksempler på slike andre terpener er furuharpiks, Ø-pinen, myrcen og 3-caren. Racemisk og optisk aktive former kan anvendes. The ratio between the components in the lure can be varied, but it is essential that the desired lures are present for as long as possible in order to achieve the most possible long-lasting effect. Besides terpinol and a-pine, other terpenes that occur in pine can also be used either instead of or in addition to terpinol and a-pine. Examples of such other terpenes are pine resin, Ø-pinene, myrcene and 3-carene. Racemic and optically active forms can be used.

Det margborer-tiltrekkende preparat ifølge oppfinnelsen inneholder terpen-hydrokarboner fra furuharpiks, og det karakteriseres ved at det dessuten inneholder etanol, bortsett fra preparater som inneholder blandinger av a-pinen og etanol som eneste aktive stoff. The pith borer-attracting preparation according to the invention contains terpene hydrocarbons from pine resin, and it is characterized by the fact that it also contains ethanol, apart from preparations containing mixtures of α-pinene and ethanol as the only active substance.

Fra Naturwissenschaften 62 (1975) s. 539 er det kjent at en blanding av a-pinen og etanol har en viss tiltrekkende virkning på biller av arten Trypodendron lineatum. men fra ibid 66 (1979) s. 528-529 vil det fremgå at den samme blanding praktisk talt ikke har noen tiltrekkende virkning på denne bille-art. Eftersom det er kjent at reaksjonen overfor en viss kjemisk blanding er spesifikk for hver art, var det ingen grunn til å anta at en blanding av a-pinen og etanol skulle ha noen virkning på andre insekter, særlig Tomicus piniperda. From Naturwissenschaften 62 (1975) p. 539 it is known that a mixture of α-pinene and ethanol has a certain attractive effect on beetles of the species Trypodendron lineatum. but from ibid 66 (1979) pp. 528-529 it will appear that the same mixture has practically no attracting effect on this beetle species. Since it is known that the reaction to a certain chemical mixture is specific for each species, there was no reason to assume that a mixture of a-pinene and ethanol would have any effect on other insects, especially Tomicus piniperda.
