Steinernema bicornutum sp. n. (Rhabditida: Steinernematidae) from Vojvodina, Yugoslavia
Russian Journal of Nematology 3 (2), 71-80
Abstract: Steinernema bicornutum sp. n., isolated from soil samples taken in Strazilovo, Vojvodina, Yugoslavia by baiting with last instar Galleria mellonella, is distinguished from other members of the genus Steinernema by two protruding horn-like papillae on the head of the dauer juvenile. The average length of the dauer stage is 770 µm, the lateral field has 8 ridges. Only second generation females and males bear a small tail mucron. Two different spicule types occur in first generation males. The species did not hybridize with S. carpocapsae and S feltiae, the latter also isolated from the type locality. Its restriction fragment length pattern of the internal transcribed spacer region of the ribosomal DNA repeat unit differ from other Steinernema species. Dauer juveniles with similar horn-like structures have been recorded from Spain and Germany. Axenic and monoxenic cultures of new species were established on artificial media. An improved time-saving method to dehydrate nematodes for permanent preparations is described.
