Population dynamics of Ichneumonidae in a mediterranean oak forest (Hymenoptera, Ichneumonidae)
S. Bordera & P. Agulló
ABSTRACT
In a Mediterranean oak forest placed in the Sierra Negrete (Chelva, Valencia, Spain) 793 individuáis were collected by means of a white Malaise trap, Townes model. alongone year period (from March 1994 to March 1995).
The phenology of this Ichneumonidae population has been investigated. The samples were separated to subfamily level. AH collected specimens belong to 13 subfamilias . The groups of greatest abundance were Cryptinae and Campopleginae with 47.28% and 31.9% respectively. They were followed by Banchinae, íchneumoninae and Cremastinae with 5.29%, 5.17% and 4.66% of relative abundance. Anomaloninae and Tersilochinae represent only 2.01% and 1.38% of the collected material, whilst the rest of subfamilies groups such as Xoridinae, Ophioninae, Orthocentrinae, Pimplinae, Metopiinae and Mesochorinae, had a relative abundance less than 1%.
According to Horstmann (1992) the Cryptinae are the predominant subfamily in a Mediterranean habitat, as they are in most other places, but only the Campopleginae are actually more abundant than in most samples from Europe outside the Mediterranean.
