In vitro rearing of the aphid endoparasitoid Lysiphlebus fabarum (Marshall) (Hymenoptera, Braconidae) was attempted. Successful permanent cultures of Aphis fabae Sc. and Myzus persicae Sulz. cells were not obtained. Therefore, parasitoid larvae were reared in 2 unnatural media, one of which included cells of Ceratitis capitata Wied. (Diptera, Trypetidae): A group of larvae was reared in a substrate to which parasitoid teratocytes had been added. Since Lysiphlebus fabarum females did not oviposit into paraffin droplets including the substrates, the larvae were transferred directly from parasitized aphids into the rearing media. Several larvae reached the final instar, but only 2 out of the 48 tested in the 3 substrates became adults. The meaning of teratocytes in in vitro rearing of Aphidiine, Braconids is discussed.
