Egg parasitoids (Chalcidoidea and Platygastroidea)
Parasitism of insect eggs, and full development to the
adult stage therein, is practised by the entire family Scelionidae
(Platygastroidea), two entire families of Chalcidoidea
(Trichogrammatidae and Mymaridae), and one or more
genera in several additional families of Chalcidoidea and
also a few Platygastridae (Platygastroidea). Representatives
of at least nine families altogether have been recorded
(whether correctly or not) as egg parasitoids of Lepidoptera
in Europe (B. Pintureau, pers. comm.), though most are
much more strongly associated with the eggs of other insects.
The most important parasitoids of butterfly eggs are in the
genera Trichogramma (Trichogrammatidae) (Plates 13b and
14), Anastatus (Eupelmidae) and Ooencyrtus (Encyrtidae) in
the Chalcidoidea, and also Telenomus (Scelionidae) and possibly
related genera in the Platygastroidea.
With notable exceptions, Lepidoptera eggs are neither easy
to find nor to identify.This, and the difficult taxonomy of major
genera such as Trichogramma and Telenomus, has so hampered
knowledge of host range in egg parasitoids that we do not
attempt to give specific host data here.
Jednocześnie w części szczegółowej autorzy zaznaczają:
Although only the Maculinea rebeli parasitoid associations
have been studied in detail, egg, larval and pupal parasitoids
are known from several other European Lycaenidae
(e.g. Bink, 1970; Fiedler et al., 1995; Shaw, 1996;
Horstmann et al., 1997; Gil-T, 2001, 2004) and the few
available data suggest that parasitism can be heavy.
