The trophic network realized for Prunus domestica L. following the identification of the species and elucidation of the relations among species, is a very complex network. We identified 14 phytophagous species (aphids), 39 predator species, 7 species of primary parasitoids, 12 species of secondary parasitoids, a species that acts both as secondary and tertiary parasitoid and 4 species of parasitoids of the predator species.
Brachycaudus cardui L. was attacked by 13 predator species and 2 species of primary parasitoids. Aphidius transcaspicus Telenga (primary parasitoids) was parasitized by Pachyneuron aphidis Bouché (secondary parasitoid).
Brachycaudus helichrysi Kalt. and Myzus persicae Sulz. were preferred only by predator species (7 respectively, 18 species of predator insects).
For Phorodon humuli Scrk. we identified 16 predator species and only one parasitoid species. This (Ephedrus persicae Frog.) was parasitized by 4 species of primary parasitoids.
The richest entomofauna was noted for Hyalopterus pruni Geoff. Thus, we identified 34 predator species and 6 species of primary parasitoids. Among primary parasitods, Ephedrus persicae Frog., Praon dorsale Hal., Praon volucre Hal. and Lysiphlebus fabarum Marshall were parasitized by species of insects that acted as secondary parasitoids (3 species, 2 species, 8 species and respectively, 2 species of secondary parasitoids for the species enumerated above).
A special situation was noted for Pachyneuron aphidis Bouché species that was identified both as secondary and tertiary parasitoid. As tertiary parasitoid we obtained this species from Alloxysta semiclausa Kieff. that had parasitized on Praon volucre Hal. (obtained from mummies of H. pruni Geoff.). |
