Cameron et al. (1989) - parasitised E. postvittana pupae were collected in eastern Australia and Tasmania in 1967 and 1969 and imported into quarantine at Nelson. Two hundred and forty-one B. teuta emerged in 1967, of which 200 were directly released; 52 emerged in 1969, of which 40 were directly released. It was cultured successfully and reared individuals were also released.



Release details:

Cameron et al. (1989) - in 1967, 200 adults were released into field cages at Nelson and Appleby, near Nelson. In 1969, 40 adults were released into field cages at Appleby. Releases were also made at Christchurch, Auckland, Hamilton and Tauranga.
