Abstract
Seven insects, Apion miniatum Germar (Coleoptera: Apionidae), Perapion neofallax (Gyll.) (Coleoptera: Apionidae), Perapion violaceum (Kirby) (Coleoptera: Apionidae), Coniocleonus excoriatus Gyll. (Coleoptera: Curculionidae), Kokujewia ectrapela Konow (Hymenoptera: Argidae), Dysaphis emicis (Mimeur) (Hemiptera: Aphididae), and Haploprocta sulcicornis (F.) (Hemiptera: Coreidae), are proposed as potential biological control agents for Emex species in Australia. The biology, distribution and recorded host range of each species is reviewed. The host specificity assessment of the first of these insects, Apion miniatum, is nearing completion.
