✦ Synopsis
The e †ects of pesticides on beneÐcial predatory arthropods have been widely studied ; this paper however deals with their e †ects on Heteroptera, an important beneÐcial insect group and food source for farmland birds. Field trials were used to evaluate pesticide e †ects under realistic conditions of application on a commercial arable farm and compared with previously published laboratory Ðndings. Fungicides were found to produce very low levels of mortality, not signiÐcantly di †erent from control treatments. Aphicides varied in their impact, producing non-signiÐcant to highly signiÐcant mortality levels. The likely ecological impact of pesticides on various heteropteran groups found within the Ðeld and Ðeld boundary is discussed.
