Abstract

This work was conducted to study some ecological and modern control studies on citrus nematode, Tylenchulus semipenetrans  infesting citrus orchards at El-menoufia Governorate. The experiments were applied at the citrus experimental farm of the faculty of agriculture , Menoufia governorate on three citrus varieties ,  Citrus sinensis (naval orange) , Citrus reticulate (Balady mandarin) , Citrus aurantifolia (Balady lemon). Experiments were divided into two parts , the first part was aimed to survey different feeding groups of nematodes associated with the rhizosphere of citrus varieties along 12 months. The second part of study aimed to biologically control citrus nematode, Tylenchulus semipenetrans , by soil application of  citrus trees with  the nematophagous fungi; Glomus mosseae  the nematophagous fungus , Arthrobotrys conoides  In addition to the local bacterial strain of Azotobacter chroococcum. The obtained results could be summarized as follow: - The most dominant parasitic nematode genera were : Tylenchorhynchus; Tylenchulus semipenetrans; Pratylenchus and Xiphinema. - The  nematophagous fungus , Arthrobotrys conoides  treatment recorded the highest reduction percentages of citrus nematode compared to other bioagents when singly applied. - The treatment of the three bioagents when applied together (Arthrobotrys conoides , Glomus mosseae, Azotobacter chroococcum) recorded the highest reduction percentages against citrus nematode . - The treatment of Mycorrhizal fungus, Glomus mosseae recorded the least reduction percentages of citrus nematode as 46.1 %. -  The treatment of the three bioagents recorded the highest increase in number of fruits per branch , the weight of orange fruit , the fruit yield
