A technique for applying small drops of insecticide solution to Myzus persicae (sulz.)

A technique is described for applying insecticide solutions accurately and rapidly to aphids. Radiochemical measurements showed that volume of 0.02 to 0.2 μl could be applied accurately and that more than 90% of the dose remained on the aphids when 0.08 μl or less was applied. There was good agreement between the radiochemical calibration land the toxicological results.
