Summary
The source of a fungistatic effect onBeauveria bassiana, which has been described from hemolymph ofPieris brassicae larvae, parasitized byApanteles glomeratus, is not situated in parasite larvae, but in teratocytes. These derivatives of the parasite serosa are floating in the host hemolymph, producing a fungistatic material, which compensates the parasitically induced weakness of host cuticle to fungus infections. From this the biological significance of teratocytes and their adaptive importance for the parasite larvae become evident.
Zusammenfassung
Die Herkunft der fungistatischen Substanz, die in der Hämolymphe parasitierterPieris-Raupen die Entwicklung des pathogenen PilzesBeauveria bassiana hemmt, wurde untersucht. Nicht dieApanteles-Larven selbst, sondern die sie stets begleitenden Teratocyten in der Wirtshämolymphe produzieren den Wirkstoff und kompensieren damit die parasitäre Schwächung der kutikulären Pilzabwehr des Wirts.
