Definitions

  • the invention relates to a material as a pheromone dispenser for attracting forest insects, in particular bark beetles, in particular turn spruce bark beetles of the type ißs typographus (book printer), comprising:
  • a beetle-borne pheromone type comprising at least one, in particular at least two, in particular at least three, beetle-borne active ingredient component (s); such as
  • a host-like type of pheromone comprising at least one, in particular at least two, host-active active ingredient component (s).
  • the poison-free control takes place by attracting the pest insects with pheromone dispenser in traps, catch trees or Fangpoltem.
  • Pheromone traps are used to monitor population development and swarming activity (monitoring) to determine the optimal exposure time. In addition, pheromone traps are also used directly for targeted pest control in bug stalks or at forest edges.
  • Pheromones are chemical compounds that are species-specifically released by insects to contact first and foremost with other species and to animate them, for example, to approach a place.
  • the active ingredient components are thus fragrances.
  • the patent DE 43 32 316 C2 discloses a means of attracting bark beetles of the species Ips typoqraphus, using beetle-borne and host-native pheromone types.
  • the population attractant consists of the beetle-borne components (S) -cis-verbenol, 2-3-2-methylbutenol, and ipsdienol; the attractiveness is significantly enhanced by host-borne components, in particular the monoterpene hydrocarbons (-) - alpha-pinene and (+) - limonene, which then triggers aggregation on the host tree.
  • Electroantennograms indicate that the male beetles of the species] ßs typoqraphus - which initially also make the host choice - have a significantly higher number of acceptors for the monoterpene hydrocarbons mentioned. Both sexes of the species, but especially the males, respond to (-) - alpha-pinene, the precursor of the pheromone component (S) -cis-verbenol.
  • (S) -cis-verbenol serves the remote attraction of both genders of the
  • the stimulation threshold for (S) -cis-verbenol is extremely low, the saturation threshold high.
  • 2-3-2-Methylbutenol a synergist of the (S) -cis-verbenol, which serves as a signal to drill, is delivered with the defecation.
  • the stimulation threshold is high, but the saturation threshold is reached quickly.
  • the male specific (R) - (-) lpsdienol is formed only after successful food intake and increases the attractiveness of the two obligate beetle-derived pheromone components to the female ip_s tvpoqraphus.
  • the temporal coincidence of attractant delivery and finding a suitable host tree is controlled by two mechanisms, the function of the individual pheromone components and their biosynthesis from plant components of the host tree. Synthetic pheromone lures then develop a particularly high efficacy in the attraction of bark beetles, when the combination of pheromone types is optimally matched and the dose of each pheromone corresponds to the natural system.
  • the known pheromone dispensers usually have two or more separately acting chambers for the different perfume components. - For a long time, they are unable to optimally deliver the pheromone combinations, which is especially true in the above-mentioned two-chamber system. They are therefore not optimally effective in their fishing performance.
  • the further developed material is distinguished by the fact that a carrier material is incorporated into the matrix which is compatible with the various beetle-borne and host-borne pheromone types, in particular the bark beetle species] fis tvpoqraphus. laden, with the formation of appropriate carrier / pheromone adducts, all drug components are involved in the adduct formation.
  • an insect glue trap is presented in the context of a multi-layer system, comprising a carrier layer, a sealant-containing pressure-sensitive adhesive layer and a protective layer. While the carrier layer according to WO 99/37146 A1 only has a supporting function, the carrier material of the new material, in addition to the supporting function, is characterized in particular by a loading function.
  • the material matrix with the integrated carrier material / pheromone adducts is thus based on a controllable active principle for the specifically necessary provision (release rate, release rate) of the pheromones and is thus applicable to various types of insects.
  • pheromone bait for the spruce bark beetle ßs tvpoqraphus is the new The concept of active ingredient is superior to the currently used baits in terms of catch rate and biological activity phase - that is, their efficiency.
  • the matrix is in particular a polymer material, the following variants being mentioned:
  • the matrix is an elastomer based on a partially crosslinked rubber, preferably a partially crosslinked natural rubber (NR), the degree of crosslinking being from 20 to 80%, in particular from 40 to 60%.
  • NR partially crosslinked natural rubber
  • the matrix is a thermoplastic elastomer (TPE) or a thermoplastic material.
  • the carrier material / pheromone adducts are distributed substantially uniformly within the matrix.
  • the loading amount of all pheromones with respect to the total amount of the carrier material / pheromone adducts is 20 to 60 wt .-%, in particular 40 to 50 wt .-%.
  • the mass ratio of matrix to the sum of the carrier material / pheromone adducts is 1: 0.5 to 1: 3, in particular 1: 1, 5.
  • the carrier material is chemically and biologically inert, the following variants being mentioned:
  • the support material is a molecular sieve based on a metal-aluminum silicate, in particular a sodium-aluminum silicate containing water of crystallization, with a predominantly hydrophilic or predominantly hydrophobic character.
  • the support material is a silica gel, which in particular is macroporous (eg 120 angstroms).
  • Silica gels are an amorphous form of silica. The spectrum of Pore size is large compared to molecular sieves. The energetic interaction is low.
  • the carrier material consists of a uniform material, for example in the form of a uniform molecular sieve type.
  • the carrier material is a carrier system, the following two variants (A, B) being mentioned:
  • the carrier system comprises:
  • a first carrier material loaded with the beetle-borne pheromone type including at least one, in particular at least two, in particular at least three, beetle-borne active ingredient component (s); such as
  • a second support material loaded with the host-borne pheromone type including at least one, in particular at least two, host-active active ingredient component (s).
  • the carrier system comprises:
  • a first carrier material loaded with the beetle-borne pheromone type, containing one, two or three beetle-borne active ingredient components;
  • a second support material loaded with the host-borne pheromone type including a first host active agent component; such as
  • the wirtsbürtige carrier material / pheromone adduct is because of the higher evaporation tendency usually equipped with a layer with moisture-inhibiting effect.
  • This layer is a latex based on a partially crosslinked rubber, in particular a partially crosslinked natural rubber.
  • the degree of crosslinking is 20 to 50%, in particular 30 to 40%. This conception can be realized in particular with the two variants (A, B).
  • the first carrier material is a predominantly hydrophobic molecular sieve of the following type:
  • This molecular sieve (short form: MS 10 A) is loaded with the two beetle-borne active components 2-methyl-3-buten-2-ol and S- (cis) -verberol, with formation of the corresponding adducts. Ipsdienol can also be added as the third active ingredient component.
  • the mass ratio (in% by weight) of the two beetle-borne active components 2-methyl-3-buten-2-ol and S- (cis) -verberol is 98: 2 to 90: 10, in particular 96: 4.
  • the second support material is a macroporous silica gel containing the first host-borne active component in the form of (-) - alpha-pinene
  • the third carrier material is a predominantly hydrophilic molecular sieve of the following type:
  • the second support material can be loaded with (+) - limonene and the third support material with (-) - alpha-pinene.
  • the mass ratio (in% by weight) of the two active substance components (-) - alpha-pinene and (+) - limonene is 80:20.
  • the inverse ratio of 20:80 is also possible.

  • the mass ratio of the beetle-borne active ingredient components to the host-borne active ingredient components is 1: 0.5 to 1: 3, in particular 1: 1.
  • the carrier materials used were molecular sieves based on sodium aluminum silicates with different empirical formulas, all of which contained water of crystallization, predominantly hydrophilic or hydrophobic in character.
