New Data on Nematodes of the Families Aporcelaimidae, Paraxonchidae, Qudsianematidae and Dorylaimidae Based on Examinations of a Raspberry Plantation in Bulgaria

The nematode fauna of an old raspberry plantation was studied by 28 bulk samples. Eleven species of four families of Dorylaimida were found. The occurrence and relative abundance of each species were calculated and the distribution of the recorded species in Bulgaria was summarised. The most abundant species of the studied families were Aporcella simpleX and Eudorylaimus subdigitalis. Discolaimoides bulbiferus and Crassolabium cf. cylindricum are new geographical records for Bulgaria and Aporcelaimus cf. americanus, Discolaimus agricolus and Eudorylaimus subdigitalis for the Balkan Peninsula. Morphometrics and microphotography based on specimens of the studied populations are presented.
