The present study identified an important physiological endpoint of sublethal effects on reproduction, as this is associated with lethargic behaviour after oral intake. As such, this is a factor that should now be incorporated into future risk assessments. Secondly, it confirmed that the assessment of sublethal effects on behaviour is needed for adequate risk assessment of 'potentially deleterious' compounds with a neurogenic target, as is also pointed out in the recent European Food Safety Authority (EFSA) guidelines.
