Die Hohenheimer Box: udEntwicklung einer Methode zur Vor-Ort-Massenzucht der Erzwespe Lariophagus distinguendus gegen Vorratsschädlingeud

摘要

Biological pest control is an important tool in stored products protection. To improve the biological control of the granary weevil Sitophilus granarius L. (Coleoptera: Curculionidae), a rearing box for the parasitic wasp Lariophagus distinguendus (Förster) (Hymenoptera: Pteromalidae) has been developed. The box contains breeding substrate as well as populations of hosts and parasitoids and is placed directly in the storage site. A special outlet prevents hosts from leaving the box while freshly emerged parasitoids are released continuously over several months. A repeated shipment of wasps has thereby become obsolete.
