SUNFLOWER SUMMER-PLANTING YIELD AS AFFECTED BY PLANT POPULATION AND NITROGEN APPLICATION RATES

A new Eurytoma species, of E.iranica Narendron and Lotfalizadeh, parasitic on Eulecanium rugulosum Arch. is described. This parasitoid was collected in April 1998 in Shiraz (Fars province), Iran. The parasitoid was mostly solitary. The rate of parasitism was 20%. Figures and a discussion on affinities of the new species with its close relatives, are presented.
