Visits were weekly carried out from April until November during 2017\/2018, and all samples were collected and checked under light microscope and stereomicroscope for insect\u2019s observation, honeydew and fungal growth in laboratory. Also breeding of insect on tree seedlings from egg hatching until honeydew production for fungal culture on it. The results recorded that the highest infection with insects was noticed on olive trees (75.5%), followed by oleander (56.6%), then fig trees (30.3%), respectively, while, disease severity were reached to 69%, 53% and 13.5% on olive, fig and oleander respectively. The results of fungal isolation and insect\u2019s identification showed to finding out <em>Alternaria<\/em> <em>alternata<\/em> on leaves and two suckers\u2019 insects were correlated with sooty mold disease. <em>Ceroplastes rusci<\/em> on fig trees and <em>Saissetia oleae<\/em> on trees of olive and oleander. The fungus <em>A. alternata<\/em> had the ability for growth on honeydew on the leaf surface as mycelium and conidia without penetration their tissues.<\/p>\n<p><strong>Keywords:<\/strong>\u00a0 Sooty mold, <em>Alternaria alternata<\/em>, Insect scale, Trees, Libya.<\/p>\n<p>Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/sjar\/wp-content\/uploads\/2019\/09\/v6n3p33.pdf\">PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zahra Ibrahim El-Gali*(1) Eman Gebreal Abdul-Raff(2) and Kamlla Abdel-Rahim\u00a0 El-Wahsh(1) (1).
