Definitions

  • the present invention relates to a means for attracting cockroaches and a method for producing such cockroach baits.
  • Cockroaches are one of the most difficult pests to control. They particularly affect food processing companies and are characterized by their largely unspecified choice of food (pantophagia). The conditions for a satisfactory control of the cockroaches by spraying the infested rooms with contact insecticides, particularly in food processing plants, cannot generally be met because of the very complex preparation of the rooms.
  • An alternative to the spraying method is the use of feeding baits, which must be specially tailored to the needs of cockroaches and which either contain an insecticide which is effective against cockroaches or are presented in a device which allows the cockroaches to be caught. The most important prerequisite for the effectiveness of such a bait substance in both cases is its attractiveness.
  • a cockroach bait should therefore contain all essential nutrients, especially carbohydrates and proteins, to a sufficient extent to be consumed under a wide variety of conditions, such as in households, canteen kitchens, butchers and bakeries. Since the bait also competes with the natural food supply, it must contain specific components of particularly high attractiveness. For example, the use of an onion extract as an attractive lure in starch-containing cockroach baits has been proposed (SM Ahmed, Int. Pest Control .18 (1976/4), 4). Cockroach baits containing non-coagulated egg powder, a starchy plant product, sugar and an insecticide are from the German patent DE 2408001 known. However, the baits described there have the disadvantage of the relatively complex production, which provides for vacuum drying, freeze drying or spray drying a homogenized aqueous or aqueous / alcoholic suspension of the components.
  • the present invention accordingly relates to a cockroach bait which contains yeast, starch-containing substances and carbohydrate-containing sweeteners, optionally in combination with insecticides, preservatives and / or granulation aids. Furthermore, the present invention relates to a method for producing such baits in granular form, preferably by extrusion.
  • the yeast present in the cockroach baits according to the invention is preferably used in the form of powder.
  • the protein portion of the yeast which is usually around 40% by weight to 50% by weight of the yeast dry matter, should be largely, preferably predominantly, in non-coagulated form.
  • the yeast is preferably present in the baits in proportions of 10% by weight to 30% by weight, in particular in amounts of 20% by weight to 25% by weight.
  • the cockroach baits according to the invention can contain further protein-containing substances, preferably soy flour, milk powder, egg powder and / or egg yolk powder.
  • the protein of these substances should preferably also be in non-coagulated form.
  • Such protein-containing additives are preferably present in the cockroach baits according to the invention not more than 30% by weight, particularly preferably not more than 20% by weight.
  • Starch-containing substances preferably contained in the cockroach baits according to the invention are oat flakes, wheat bran, rice bran, wheat flour, rice flour or mixtures thereof.
  • the starch-containing substances are preferably contained in the baits in proportions of 40% by weight to 70% by weight, particularly preferably in amounts of 50% by weight to 60% by weight.
  • Carbohydrate-containing sweeteners which are present in the cockroach baits according to the invention are preferably glucose, honey, fructose, sucrose or mixtures thereof. Commercial household sugar (sucrose) is particularly preferably incorporated.
  • the sweeteners are preferably in ⁇ Ménan ⁇ parts of 2 wt .-% to 20 wt .-%, particularly preferably present in amounts of 5 wt .-% to 10 wt .-%, in the baits.
  • the bait compositions according to the invention can contain granulation aids in addition to the constituents mentioned.
  • all customary aids can be used for this which do not negatively influence the action of the attractants.
  • Extrusion aids preferably used in the preferred extrusion process are glycerin, polyethylene glycols, ethoxylated fatty alcohols, molasses and lignin sulfonates. Lignin sulfonates and / or glycerol are particularly preferably used.
  • the granulation aids are preferably incorporated into the baits according to the invention in amounts of not more than 10% by weight, particularly preferably in amounts of 2% by weight to 5% by weight.
  • insecticides from the group of feeding poisons or contact poisons may be present in addition to the previously mentioned components. If present, insecticides are preferably used in amounts of 0.1% by weight to 1.0% by weight, in particular from 0.2% by weight to 0.5% by weight. Insecticides which are preferably used are compounds which are selected from the groups of chlorinated hydrocarbons, phosphoric acid esters, carbamates and pyrethroids. The particularly preferred compounds include chlorpyrifos and azamethiphos from the group of phosphoric acid esters, phenothrin from the group of pyrethroids and cartap from the group of carbamates.
  • the cockroach baits according to the invention can contain cockroach pheromones, humectants, preservatives and / or dyes as further constituents. These optional additives are not more than 10% by weight, preferably not more than 3% by weight.
  • the cockroach baits according to the invention are produced by intensive mixing of the individual components, for example in Lödige mixers or duplex kneaders.
  • the order in which the individual constituents are added is largely arbitrary, but it is advisable to add the constituents and liquids contained below 10% by weight in the product as the last.
  • the most homogeneous bait mass can then be pressed and shaped.
  • the bait mass is preferably granulated.
  • the granulation can be carried out by build-up granulation or by compacting granulation, the compacting granulation being preferred.
  • the compacting granulation can be carried out using all known methods, such as, for example, by extrusion, roller compacting or tableting.
  • the method according to the invention without drying steps, provides largely uniform consistency without dust, which can easily be filled into conventional bait containers, for example flat plastic containers with all-round seals and insect accesses on the sides.
  • the cockroach bait B1 according to the invention characterized below by its composition was obtained by mixing the constituents in a duplex kneader mixer, first mixing oatmeal and yeast, then adding sucrose, lignin sulfonate, preservative, glycerol and water to the mixer, and extrusion a worm gear through a perforated plate (diameter of the openings 3 mm) and automatic cutting to a length of about 3 mm to 5 mm:
  • An insecticide-containing bait B2 was produced as described in Example 1.
  • the water content of the bait mass of Example 1 was reduced to 12.00% by weight while maintaining the remaining proportions, for which 0.50% by weight of the insecticide chlorpyrifos was incorporated.
  • the easy expandability of the mass and the positive properties of the product were in no way impaired.
  • Preimaginal cockroach larvae of the most common species BJatteJIa germanica (German cockroach) (100 specimens), Blatta orie ⁇ ta Jis (oriental cockroach) (50 specimens) and Periplaneta americana (American cockroach) (50 specimens) were separated according to species in a glass ⁇ vessel (42 cm x 28 cm x 28 cm), the bottom of which had been lined with filter paper, which contained the droppings sample tube as a refuge and a Petri dish with moist cotton wool as a drinker, and in each of which a small dish (diameter 5 cm) with 500 each mg or 1000 mg of bait according to Example 1 (B1) and comparative bait VI had been laid out without additional feeding over a period of 10 days.
  • the vessels were in an air-conditioned room with a temperature of 28 ° C and a relative humidity of 75%.
  • the amount of feed consumed was supplemented daily and the weight loss of the bait masses determined, whereby the weight changes due to water absorption or release from the ambient air were taken into account by comparison with a similar bait stored outside the cockroach area.
  • the location of the bowls was also changed every day.
  • the amounts of feed consumed by the cockroaches during the test period were in the relative proportions given in Table 1.
  • Table 1 Weight loss of the bait [% by weight]
