The primary (key) pest of the globe artichoke,Cynara scolymusL. is the artichoke plume moth,Platyptilia carduidactyla(Riley) (Lepidoptera: Pterophoridae) (Lange 1941, Lange et al. 1954). The control program for the plume moth consists generally of applications of either methyl or ethyl parathion (or combinations of these) at intervals of 7–14 days. The chrysanthemum leafminer, previously known as Phytomyza atricornis Meigen, and now considered asP. syngenesiae(Hardy) (Diptera:Agromyzidae) (Griffiths 1967, Steyskal 1969) is a secondary pest periodically causing severe economic damage to the globe artichoke. The form of this damage is reduced plant vigor from extensive leaf mining.
