Abstract

Die Membran des Einsteckmikrofons ist so gebaut, dass sie dem seitlichen Druck des Getreides beim Einstechen und Herausziehen des Mikrofons sicher standhalten kann. Über die Membran des Mikrofons (2) werden Schwingungen und Umgebungslaute, also der Umgebungsschall von fressenden Larven aufgenommen, die über die Auswertungseinheit (3) durch einen handelsüblichen Verstärker einem Kopfhörer zum Abhören zugeführt werden.Detection of pest infestation on cereals by grain analog, acoustic signal transmission, characterized in that a plug-in microphone (1), which can be extended by telescopic tubes if necessary, so in grain silos can be introduced that the membrane of the microphone, attached to itself directly attaching cereal grains can. The membrane of the plug-in microphone is built so that it can withstand the lateral pressure of the grain during insertion and removal of the microphone safely.

Description

Die Biologische Bundesanstalt schätzt den jährlichen Getreideverlust durch Schädlinge in Deutschland auf 2%. Der Getreideverlust kann dann wirksam vermieden werden, wenn ein Schädlingsbefall so früh wie möglich entdeckt werden kann.The Biologische Bundesanstalt estimates the annual crop loss caused by pests in Germany at 2%. The loss of grain can then be effectively avoided if a pest infestation can be detected as early as possible.

In Deutschland verursachen hauptsächlich Kornkäfer (Sitophilus Granarius) und zunehmend auch Reiskäfer (Sitophilus Oryzae) diesen Verlust. Während erwachsene Käfer relativ einfach durch Sieben des Getreides zu finden und auszusortieren sind, gibt es nach dem derzeitigen Stand der Technik keine adäquate Methode Käferlarven im Korn zu detektieren.In Germany, mainly grain beetles (Sitophilus granarius) and increasingly also rice beetles (Sitophilus oryzae) cause this loss. While adult beetles are relatively easy to find and sort out by sieving the grain, there is no adequate method of detecting beetle larvae in the grain according to the current state of the art.

Da die weiblichen Käfer zur Eiablage ein Loch in das Getreidekorn bohren und danach das Korn wieder sorgfältig verschließen, ist ein Befall durch Sichtprüfung regelmäßig nicht zu erkennen. Folge hieraus ist, dass die aus dem Ei schlüpfenden Larven sich in der Regel unbeobachtet entwickeln und dabei das Getreidekorn aushöhlen bevor dieses geerntet werden kann.Since the female beetles drill a hole in the cereal grain for oviposition and then carefully close the grain again, an infestation by means of visual inspection is usually not recognizable. The consequence of this is that the larvae hatching from the egg usually develop unobserved and hollow out the grain before it can be harvested.

Herkömmliche Methoden setzen bislang auf ein Aufschwemmverfahren, das heißt ist der Hohlraum des ausgefressenen Getreidekorns groß genug, kann durch Aufschwemmen der Getreidekörner im Wasser der Gewichtsverlust befallener Körner festgestellt werden. Dieses Verfahren beeinträchtigt die Qualität des Korns und realisiert nicht immer zuverlässige Ergebnisse.Conventional methods rely on a Aufschwemmverfahren, that is, the cavity of the eaten cereal grain is large enough, can be determined by flooding the grains in the water of weight loss of infested grains. This process affects the quality of the grain and does not always achieve reliable results.

Die Methode des Larvenlauschers setzt bereits in einem Stadium an, bevor das Korn merklich ausgehöhlt ist. Mit dem Einsteckmikrofon kann bereits nach dem Schlüpfen der Larve, also zum frühest möglichen Zeitpunkt ein Schädlingsbefall dadurch festgestellt werden, dass deren Fressgeräusche akustisch wahrnehmbar gemacht werden.The method of the larval exchanger begins at a stage before the grain is noticeably eroded. With the plug-in microphone can already be determined by the hatching of the larva, so at the earliest possible time a pest infestation that their eating sounds are made acoustically perceptible.

Ohne das Einsteckmikrofon und den Verstärker können die leisen und für das menschliche Ohr nicht wahrnehmbaren Fressgeräusche nicht abgebildet werden.Without the plug-in microphone and the amplifier, it is impossible to reproduce the low-pitched eating sounds that are imperceptible to the human ear.

Zu diesem Zweck wird die Abhöreinheit des Einsteckmikrofons mit einem kombinierten Schalter- und Lautstärkeregler verwendet.For this purpose, the monitoring unit of the plug-in microphone is used with a combined switch and volume control.

Der Verstärker wird von einer handelsüblichen 9 V Batterie versorgt.The amplifier is powered by a standard 9V battery.
