| Abstract | ||||
| Mulberry (Morus spp.) is cultivated throughout the world wherever silkworms are raised where their leaves were used as food for silkworms. Many countries were cultivated mulberry trees in fields such as China, Korea and India. Others cultivated them as wild trees around the fields of different crops or at the side of roads and streams (Duke, 1983) . Egypt is one of the second categories in mulberry cultivations. Survey of mulberry scale insects (Hemiptera Coccoidea) in ten Governorates (Cairo, Qualyobia, Sharkia, Menofia, Gharbia, Kafer-El Sheikh, Northern coast, Giza, Fayoum, and Beni-Sweaf) in which Mulberry trees are concentrated, for two successive years to determine the most prevailing insects. The work was conducted from early June 1998 till late May 2000. Trees often used as ornamentals, roadsides or boundary markers. Mulberry like most of the economic plantations and field crops is also subject to attack of a vast pests complex belonging to a large number of insect orders which affect the growth of mulberry and cause considerable damage to the plant and loss in leaf yield. Results revealed fourteen species belonging to eleven genera related to five Families of the super-family Coccoidea. Among them, H. lataniae, Asterolicanium pustulans (Cockerell), C. floridensis, Coccus hespiridum Linnaeus, Pulvinaria psidii Maskell, and I. seychellarum were the six major insects belonging to Super-Family Coccoidea that infest Mulberry trees in the 10 studied Governorates. On the other hand, Qualyobia and Sharkia represented the most two Governorates where the surveyed fourteen insect species distributed allover the 10 Governorates. H. lataniae, C. floridensis and I. seychellarum were abundant in all Governorates and were able to survive under its variable weather conditions. | ||||
