Тhe Species of Superfamily Chalcidoidea – Parasites of Aphidophagous

Abstract

The species of the family Syrphidae are one of the most important predators of the peach leaf aphids on tobacco. In

the complex food chain, aphidophagous hoverflies are attacked by a wide range of parasites. During tobacco

vegetation, in the Prilep area, we applied the following methods: survey of 20 tobacco stalks and survey of 100

tobacco leaves, in 10 days interval, 2003-2005. The prime material collected from the nature, further is cultivated and

analysed under laboratory conditions. Parasited larva of Syrphidae, feeds with aphids and perform its bioregulatory

role. Parasite species are activated after the larva of hoverflies is transformed into a puppet stage. They are feeding

on tissues and organs of the hoverflies and destroy them. Were identified three parasite species from superfamily

Chalcidoidea, eclosed from pupae of hoverflies: Pachyneuron grande (Pteromalidae), Pachyneuron cf. grande

(Pteromalidae) and Syrphophagus aeruginosus (Encyrtidae). The most numerous is the parasitic specie P. grande. It

was registered as a parasite on: Sphaerophoria scripta, Sphaerophoria rueppelli, Episyrphus balteatus, Scaeva pyrastri

and Eupeodes corollae. P. cf. grande is a parasite on: S. scripta and S. rueppelli. S. aeruginosus is a parasite on: S.

scripta, S. rueppelli, S. pyrastri and E. balteatus. The emergence of parasitic species depends on the occurrence of

host-hoverflies, while the emergence and development of aphidophagous hoverflies depends on the occurrence of

the peach leaf aphids on tobacco and climate conditions of the area. This study may contribute in strategies of

biological control of plant pests and IPM implementation.
