We tested effectiveness of the neonicotinoids clothianidin and thiacloprid against Medfly.
Both caused 100% adult mortality within 48 h after direct application.
Efficacy of both neonicotinoids against adult declined with increasing residue age.
Both neonicotinoids showed efficacy on the immature stages (egg, larvae) and caused adult deformation.
Clothianidin appeared more effective than thiacloprid in controlling medfly.
