Target pest: Epiphyas postvittana (Lepidoptera: Tortricidae), light brown apple moth
Agent introduced: Eupsenella sp. 1 (Hymenoptera: Bethylidae)
Cameron et al. (1989) - in 1969 parasitised E. postvittana larvae were collected in eastern Australia and Tasmania and imported into quarantine at Nelson. One hundred and fifteen Goniozus sp. [but see Berry (1998) below for identification of voucher specimens] emerged, of which 100 were directly released.
Berry (1998) - the specimens imported 1969 were recorded as Goniozus sp. However, examination of voucher specimens has shown that the importation comprised a mixture of Eupsenella sp. 1, Goniozus jacintae and Sierola sp. 1.
Cameron et al. (1989) - in 1969, 100 adults were released into field cages at Appleby, near Nelson, and Nelson.
Berry (1998) - the 100 adults released in 1969 were considered to be Goniozus sp. However, examination of voucher specimens has shown that the importation comprised a mixture of Eupsenella sp. 1, Goniozus jacintae and Sierola sp. 1.
Berry (1998) - Eupsenella sp. 1 has not been collected in New Zealand and has presumably not established.
