Description
Summary:The rhabditid nematode, Phasmarhabditis hermaphrodita is a lethal parasite of certain terrestrial gastropods and has been shown as a biocontrol agent under laboratory and field conditions. In Egypt, P. hermaphrodita was isolated for the first time from different species of terrestrial gastropods found associated with various crops at Aga and Mansoura districts of Dakhalia Governorate during the year 2000/2001. Females and dauer larvae (IJs) were described and illustrated based on the light microscope. Males are not found as this species seemed to be protandrous. PCR analysis confirmed nematode identification. The Egyptian isolate of P. hermaphrodita was found to be shorter and lower in width than the British isolate. V%, a, b and c parameters showed detectable variations between two isolates with values of 54%, 17.7, 4.28, 13.7 in the Egyptian isolate, and 51%, 19.5, 7.2 and 15.8 for the British isolate, respectively.
