Biocontrol introduction
Target pest: Coleophora mayrella (Lepidoptera: Coleophoridae) = Coleophora spissicornis, banded clover casebearer
Agent introduced: Eurytoma sp. (Hymenoptera: Eurytomidae)
Imported:
1961
Import source:
Near Freiburg, Germany
Import notes:
Cameron et al. (1989) - Eurytoma sp. was imported in 1961 as parasitised Coleophora deauratella host larvae collected from near Freiburg, Germany. From the shipment of 4,500 C. deauratella larvae, 11 female and four male Eurytoma sp. emerged, but they were still under quarantine when an outbreak of the mite Pyemotes zwoelferia occurred and were destroyed along with the rest of the imported material.
Released:
Cameron et al. (1989) - not released.
General comments:
Taxonomic note (22 September 2025) - Coleophora spissicornis is reported present in New Zealand as the banded clover casebearer by Cameron et al. (1989) and other authors. Baldizzone (1994) synonymised C. spissicornis with C. mayrella and Stubner (2007) treats it as a synonym of C. mayrella in his revision of the C. frischella taxonomic group (though noting some uncertainty about this due to the type specimen of Porrectaria spissicornis being damaged.) Coleophora mayrella, but not C. spissicornis, is reported to be present in New Zealand by Biota of New Zealand (Landcare Research Biota of NZ - accessed 22 September 2025) and the New Zealand Arthropod Collection (Landcare Research SCNZ - accessed 22 September 2025).
