Agent introduced: Periscepsia carbonaria (Diptera: Tachinidae)

Import source:


Import notes:

Cameron et al. (1989) - Periscepsia carbonaria was imported from Pakistan in 1970-71 as part of a programme to introduce A. ipsilon parasitoids into New Zealand. As it was unable to be released from this importation, a re-importation was made in 1985. A sex ratio imbalance resulting from poor emergence out of the 1985 material caused the laboratory cultures to fail after two generations. Further importations of A. ipsilon parasitoids from Pakistan were made in 1986 but did not include P. carbonaria as field infestations in that country were low.

Release details:

Cameron et al. (1989) - not released.
