On a cereal field with pesticide treated areas, and areas left unsprayed since 1986, hymenopteran parasitoids were collected using emergence traps. In total, and on most collecting dates, more species were collected on the unsprayed areas. The log‐series index was also greater for the unsprayed plots (areas and trap groups) than for the sprayed plots. The dominance of the most abundant species decreased on the unsprayed areas.
