Previous studies concentrated
mainly on the rearing and development of larvae
(Hogsette, 1992; Barnard et al., 1998) and there are only
a few small-scale laboratory studies on the rearing of
adults (see e.g., Shipp & Osborn, 1967; Zhemchuzhina &
Zvereva, 1985; Zvereva & Zhemchuzhina, 1988), some
of which determined only potential (and not actual)
female fecundity.
