[Syrphidae] Rearing aphidophagous species
Mon, 5 Jun 2000 16:17:08 +0100
Hi Chris. There is quite a lot in the literature on apple aphid
predators, as you probably know, including syrphids (eg Tamaki's
papers in the 1960s and 1970s). Rearing to the adult should not
be a problem since many species have no diapause; even in the
species with diapause it shouldn't be to much of a problem.
However, many species have never been cultured, mainly because
of problems in getting them to mate in cages. The best reference to
larvae and rearing is Graham Rotheray (1993) Colour guide to
syrphid larvae. Dipterists Digest 9:1-155, published as a book and
available from the Natural History Bookstore (www.nhbs.com).
There is also quite a lot on pesticide effects on syrphids, which are
a standard test organism in the regulatory programme in Europe
(see e.g. Hassan et al 1987 Z angew Ent 103: 92-107). Adults are
reasonably easy to identify - your best bet would probably be
