Abstract

Three-piece pheromone trap for catching the moth of the oak processionary moth with the help of sexual attractants: actual trap body (2-part) + swap body

Description

Since 1995, an enormous increase in density of this formerly classified as rare butterfly species in Germany. The caterpillar hairs lead to allergies in humans. In trees, the insect prefers light oak forests, stand edges and single trees. It comes in the oak forests, especially in Bavaria increasingly to light and Kahlfraß. Control measures are carried out ( www.eichenprozessionsspinner.org ).

Therefore is a high expenditure for the coming years the monitoring, damage prognosis, risk assessment and control measures of this insect required. First and foremost problem is, with a reliable one Forecasting method generally a demarcation of the distribution area to allow and as early as possible an estimate of population density and expected Damages and impairments, so that appropriate and effective countermeasures are planned and can be initiated.

The only large-scale feasible and standardizable Prognosemethode is a monitoring of moth flight with Help of pheromones in appropriate case systems. Hereby leave density fluctuations as well as the transition to gradation in the populations and thus one can early on react to hazardous situations.

• – einen geeigneten Fallentyp zu entwickeln, der den Falter zum einen ausreichend gut in der Falle fängt. Solche Fallen müssen insektentypisch entwickelt werden, da Insekten hinsichtlich Form, Farbe, Öffnungen der Falle oder auch beim Anbringen der Falle am Baum jeweils arttypisch reagieren und nur angepasste Falle „akzeptieren”. Das Insekt wird durch den Lockstoff „Pheromon” angelockt und fängt sich in der Falle.
• – eine praxistaugliche Falle zu verwenden, die wegen des großflächigen Einsatzes über eine längere Falterflugzeit einen geringen operativen Aufwand bei den Überwachungstätigkeiten in den Revieren ermöglicht. Die Falle werden in regelmäßigen Zeitabständen von den gefangenen Falter geleert, die Anzahl der Falter wird dokumentiert und bilden eine Grundlage zur Lageeinschätzung.
• – Den Herstellungsaufwand gering zu halten, da die Stückzahlen der Falle gewisse Mengen nicht überschreiten und es für Waldbesitz nur in gewissem Maß möglich ist, Kosten tragen zu können.

These pheromone predictions require that

• - To develop a suitable type of trap that captures the moth sufficiently well in the trap. Such traps must be developed insect-typical, as insects react in terms of shape, color, openings of the trap or even when attaching the trap on the tree each type of art and "accept" only adapted trap. The insect is attracted by the attractant "pheromone" and trapped in the trap.
• - To use a practical case, which allows a small operational effort in the monitoring activities in the areas because of the large-scale use over a longer mothwalking time. The traps are cleared at regular intervals by the trapped butterflies, the number of butterflies is documented and form a basis for assessing the situation.
• - To keep the production costs low, as the number of cases of the trap does not exceed certain quantities and it is possible for forest ownership only to a certain extent to be able to bear costs.

The Registered for utility model protection pheromone trap oak processionary moth has been developed and fulfilled in recent years scientifically carried out these tests.

• – Behältnis aus lichtdurchlässigem Plastik
• – Größe entsprechend eines ca. 1,5 Liter umfassenden Flaschentyps
• – 2-teiliges Gehäuse mit verschließbarer Öffnung zur Pheromonbestückung oben, mittigem Steckverschluss zum Öffnen der Falle, um Pheromon, Fangflüssigkeit und gefangene Falter zu trennen, Aufhängvorrichtung zur Befestigung am Baum

Their essential features are:

• - Container made of translucent plastic
• - Size corresponding to a bottle type of approx. 1.5 liters
• - 2-part housing with lockable pheromone opening at the top, central buckle for opening the trap to separate the pheromone, catching liquid and trapped moths, hanging device for attachment to the tree
