ABSTRACT
In a survey, specimens of dagger nematode (Xiphinema sp.) were collected from soil around the rhizosphere of
citrus trees (Citrus sinensis (L.) Osbeck) with poor growth appearance and low yield from EL-Nobarria, EL-Behera
governorate, northern Egypt, during 2012-13. Dagger nematode (Xiphinema rivesi Dalmasso, 1969) was identified
on morphology of females that included female body and total stylet (odontostyle and odontophore) length, location
of guiding ring and excretory pore from oral aperture, shape of head and tail including various tail measurements
and vulva percentage in relation to body length. This is the first report of this nematode from Egypt, Africa. The
values of the morphological parameters completely fall within the previously reported ranges for X. rivesi.
