Biocontrol introduction

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

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

Imported: 1967-69

Import source: Eastern Australia and Tasmania

Import notes: 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) - 100 adults, from specimens imported 1967-69, were released at Appleby and Nelson in 1969. 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.
