ABSTRACT: The research on biology and ecology of Mottled Umber Moth
–Erannis defoliariaCl. (Lepidoptera, Geometridae) was carried out in the period
1985–2009 in oak forests in Serbia. Mottled Umber Moth was mainly in
the latency during the investigation. Only at the locality Miroč in East Serbia
and in Forest unit Zlatica (National Park Djerdap), it was dominant in the
complex of early defoliators. Natural enemies ofE. defoliariaand especially
parasitoids and hyperparasitoids are important mortality factors.
Egg parasitoidTrichogrammasp. (Hym., Trichogrammatidae) was recorded
at few localities in the vicinity of Belgrade and in the wide area of National
Park Djerdap. They are nonspecific parasitoids. Somewhat more specific Telenomus
minutus(Hym., Scelionidae) was recorded from East Serbia – locality
Miroč. Larval parasitoids are Protapanteles immunis,Cotesia limbata,C. jucunda(
Hym., Braconidae);Casinaria ischnogaster,Casinaria moesta,Phobocampe
crassiuscula, Phobocampe pulchella, Phobocampe sp. (Hym.,
Ichneumonidae), Euplectrus bicolor, Eulophus larvarum (Hym., Eulophidae),
Blondelia nigripes,Phryxe magnicornis,P. nemea,Peribaea fissiconis(Diptera,
Tachinidae). There are 16 parasitoids recorded. Five species of hyperparasitoids
recorded on E. defoliariaare following: Gelis areator,Bathythrix lamina
(Hym., Ichneumonidae), Perilampus ruficornis (Hym., Perilampidae), Habrocytus
chrysos. (Hym., Pteromalidae), Tetrastichussp. (Hym., Eulophidae).
