Abstract
Observation made over a 4-year period in pinewoods of Apulia Region (South Italy) on Thaumetopoea pityocampa (Denis Sciffermüller) (Lepidoptera: Notodontidae) prepupae and pupae, indicated the following natural enemies complex: Hexamermis sp. (Nematoda: Mermithidae), Phryxe caudata (Diptera: Tachinidae), Villa brunnea and Hemipenthes velutina (Diptera: Bombyliidae), Conomorium pityocampae (Hymenoptera: Pteromalidae), Coelichneumon rudis and Cryptus sp. (Hymenoptera: Ichneumonidae), Beauveria bassiana and Isaria farinosa (formerly Paecylomices farinosus) (Ascomycota: Hypocreales). The moths and the parasitoid species emerged sequentially and, although these natural enemies show irregular distribution, they together controlled up to 60% of T. pityocampa pupae. Ecological implications of such parasitism are being discussed
