Abstract
Recently the hemispherical soft scale Saissetia coffeae (Walker) (Hemiptera: Coccidae) is considered one of the most important pests in Egypt. It is polyphagous and is a well known pest of coffee, ornamental shrubs and greenhouse plants. The honeydew produced by heavy populations allows the development of sooty mould fungi on the host plant. The aim of the present work is to survey host plant species, their distribution, natural enemies and seasonal abundance of S. coffeae during 2020-2022 in Egypt. It attacks 20 host plants, three of them recorded here for the first time in Egypt. These are Ficus nitida, Psidium guajava and Pinus halepensis and are distributed in nine governorates. These are, Alexandria, Assiut, Aswan, Gharbiya, Giza, Mersa Matruh, North Sinai, Qena and South Sinai. The results, also, indicated that this species parasitized by 13 species of aphelinids, encyrtids and pteromalid of parasitiod species. Two of them recorded here for the first time in Egypt. These are Diversinervus elegans Silvestri and Metaphycus zebratus (Mercet) as well as seventeen species of predators were recorded and collected from concerned specimen under investigation here found in Egypt. Six of them are new records. These are Chilocorus bipustulatus L., Clitostethus arcuatus Rossi, Cydonia vicina isis Cr., Pharoscymnus various Kirsch., Rhyzobius lophanthae (Blaisdell) and Rhyzobius littura Fab. Special references of this pest species are provided.
