Abstract

Menthon ist ein Mittel zum Schutze vor den Bienenparasiten Varroa jacobsoni und dessen Brut.Menthon is a means of protection against the bee parasite Varroa jacobsoni and its brood.

Description

Für die Bekämpfung des seit einigen Jahren auf der ganzen Welt verbreiteten Bienenparasiten Varroa jacobsoni werden bis heute Stoffe eingesetzt, die toxisch sind und toxische Rückstände hinterlassen, zum Beispiel auch im produzierten Honig. Ein weiterer Nachteil dieser Stoffe ist ihre Unwirksamkeit auf die Brut des Para- siten im Bienenstock. So wird zur Zeit in erster Linie das toxische lsopropyl-4,4'-dibrombenzilat angewendet: bekannt sind ferner 1.23.4,7,7-Hexachlorbicyclo-(2,2,l)-2-hepten-5,6-bis-oximethylensulfit oder ein chloriertes Camphen.To combat the bee parasite Varroa jacobsoni, which has been widespread all over the world for a number of years, substances that are toxic are still used today and leave toxic residues, for example in the honey produced. Another disadvantage of these substances is their ineffectiveness on the brood of the Para- sit in the beehive. At the moment, the toxic isopropyl-4,4'-dibromobenzilate is primarily used: 1.23.4,7,7-hexachlorobicyclo- (2.2, l) -2-heptene-5,6-bis- are also known oxymethylene sulfite or a chlorinated camphene.

Es ist die Aufgabe der Erfindung, ein nicht toxisches Mittel und ein Verfahren zum Schütze von Bienen vor Varroa jacobsoni bereitzustellen, das die oben angeführten Nachteile nicht aufweist. Diese Aufgabe wird, wie in Anspruch 1 und 2 angegeben, gelöst. Es handelt sich um die parasitenschädigende Wirkung des Menthons, das zum Beispiel auch im Pfefferminzö! in unterschiedlichen Anteilen vorkommt und dessen parasitenschädigende Wirkung noch nicht beschrieben wurde. Wirksam sind das D-Menthon. L-Menihon und D.L- J5 Menthon. Versuche mit ähnlich strukturierten Stoffen, zum Beispiel Menthol, bei denen parasitenschädigende Wirkung vermutet wurde, verliefen ohne positives Ergebnis. Weitere Versuche haben übereinstimmend ergeben. daCi die dem Menthol nahestehende Verbindung Menthon die Wirkung hat. daß die Varroa jacobsoni in mehreren Punkten beeinflußt wird. Zum einen verläßt sie nach Menthonkontakt die Biene sofort und geht dann aller Wahrscheinlichkeit nach an Nahrungsmangel zugrunde. Zum anderen wird die Varroabrut abgetötet. Dies konnte bei mit Mentrron behandelten Biencnstökken beobachtet werden, wobei auch eine l.ang/eitwirkung festgestellt wurde. Verwendet wurde zu diesen Untersuchungen u. «.ein Menihon-Präparat der Zusammensetzung: It is the object of the invention to provide a non-toxic agent and a method for protecting bees from Varroa jacobsoni which does not have the disadvantages mentioned above. This object is achieved as stated in claims 1 and 2. It is about the parasite-damaging effect of menthone, which, for example, is also found in peppermint! occurs in different proportions and its parasite-damaging effect has not yet been described. The D-menthone are effective. L-Menihon and DL- J5 Menthon. Experiments with similarly structured substances, for example menthol, which were suspected to be harmful to parasites, did not yield any positive results. Further attempts have consistently shown. that the menthol-related compound menthone has the effect. that the Varroa jacobsoni is influenced in several points. On the one hand, it leaves the bee immediately after contact with menthone and then in all probability perishes from a lack of food. On the other hand, the Varroa brood is killed. This was treated with Mentrron Biencnstök observed ken, where one l.ang / eitwir effect was observed. A Menihon preparation with the following composition was used for these investigations.
