Abstract

A laboratory bioassay was used to evaluate the effect of residues from 10 orchard pesticides on mortality of Dolichogenidea tasmanica a parasitoid of leafrollers Adult parasitoids were caged in Petri dishes that had been sprayed with the field rate of the pesticides Mortality was assessed over 7 days and classified using the laboratory criteria defined by the International Organization for Biological and Integrated Control of Noxious Animals and Plants Residues of buprofezin emamectin benzoate lufenuron tebufenozide and thiacloprid were harmless (lt;30 mortality) to D tasmanica adults in the 7 days after treatment Indoxacarb and lime sulphur residues were moderately harmful (8099 mortality) while carbaryl diazinon and spinosad residues were harmful (>99 mortality) The implications for leafroller control in pipfruit production programmes are discussed
