Biocontrol introduction

Target pest: Epiphyas postvittana (Lepidoptera: Tortricidae), light brown apple moth

Agent introduced: Sierola sp. 1 (Hymenoptera: Bethylidae)

Imported:

1969

Import source:

Australia

Import notes:

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 1967-69 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.

Released:

1969

Release details:

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.

Establishment:

Berry (1998) - Sierola sp. 1 has not been collected in New Zealand and has presumably not established.
