| Abstract | ||||
| Habib and El-Kady (1961) described Dysaphis (Chomaphis) foeniculus Theobald. The present author redescribed this species from specimens collected from common fennel, carrot and dill plants from North Sinai during 2003 among the species of living aphids on common fennel it is possible to recognize D. foeniculus for its colour and some morphological differential characteristics. This aphid is considered as the main aphid infesting Umbelliferous plants wherever are grown. It attacks the newly tender terminal growth. The secretion of honey dew serves as a medium for sooty mould fungus grows on the infested stalks. Consulting with Dr. Victor Eastop (The Natural History Museum, London) confirmed that the drawing by Habib and El-kady (1961) for Dysaphis foeniculus Theobald does not resemble the original description of this species. He confirmed that the present slides resemble the original description. | ||||
