Agent introduced: Phanerotoma fasciata (Hymenoptera: Braconidae)

Imported:

Import source:

Georgia, USA

Import notes:

Cameron et al. (1989) - two shipments of P. fasciata (imported as P. tibialis) were received from Georgia, USA. The first, in December 1932, consisted of 40 codling moth larvae previous exposed to P. fasciata; no parasitoids emerged from these. The second, in January 1934, consisted of about 140 codling moth larvae, from which only three P. fasciata, all females, emerged. One escaped, the other two were allowed to oviposit (unmated) in codling moth eggs; a few male progeny were reared from these eggs.

Released:

Cameron et al. (1989) - in 1934 one female escaped, otherwise not released.
