Summary
Ziel dieses Projektes ist die Entwicklung einer Zuchtbox zur kontinuierlichen Freilassung von Lagererzwespen (Lariophagus distinguendus) gegen Kornkäfer (Sitophilus granarius) in Getreidelagern des ökologischen Landbaus. Diese neue Methode soll eine preisgünstige, leicht einsetzbare und effektive Alternative zur bisherigen Ausbringmethode darstellen.
Im Rahmen des auf zwei Jahre festgelegten Projekts muss die Art des Zuchtmediums, die optimale Ansatzmenge der Wirte und der Parasitoide sowie eine geeignete Auslassöffnung aus der Zuchtbox entwickelt werden. Darüber hinaus soll für Nützlingsanbieter eine Anleitung zu Erstellung und Einsatz der Zuchtfässer erarbeitet werden. Anwender und Berater werden über Publikationen, das Internet, Messen und Fortbildungsveranstaltungen informiert. Eine schnelle kommerzielle Umsetzung soll durch eine enge Zusammenarbeit mit Produzenten der Lagererzwespen erfolgen.
Summary translation
Insect pests are a threat for stored products causing huge losses especially in organic farming. One of the major pests especially in grain stores in Germany is the granary weevil Sitophilus granarius L.. The parasitic wasp Lariophagus distinguendus (Förster) can be used as a biocontrol agent against S. granarius and is commercially available in different European countries. Nevertheless surveys in South Germany showed that only 12 % of producers in organic farming use L. distinguendus in their storages to control granary weevils because the current mode of application is time consuming and to expensive.
To improve the use of L. distinguendus against the granary weevil the project aims to develop a mass rearing device which can be placed in the grain store to obtain a continuous release of the wasps throughout the season. The rearing device will consist of host plant seeds, hosts and parasitoids. Instead of Sitophilus granarius the bean weevil Acanthoscelides obtectus will be used as a substitute host.
In this context, the following aspects will be investigated:
1.The selection of suitable host seeds for the continuous rearing of the beetles and wasps in the mass rearing device.
2.The determination of the start amount of seeds, hosts and wasps, to guarantee a continuous release of wasps throughout the season.
3.The development of a mesh covered opening of the rearing device.
The obtained results will be passed on to farmers, advisers in ecological farming and scientists using al kind of different media (publications, internet, meetings, exhibitions,...).
