Morphology of Hoplolaimus seinhorsti as seen by scanning electron microscope

  • N. Vovlas


The plant parasitic nematode Hoplolaimus seinhorsti Luc, 1958 was described from roots and soil of cotton (Gossypium hirsutum L.) in Madagascar (Luc, 1958). Later, it was found in association with various crops in Nigeria, Southern India, Guatemala, Philippines, Thailand, Indonesia and Sri Lanka (Van den Berg, 1976; Lamberti and Ekanayake, 1983a and b). The morphology of H oplolaimus species is based on observations made with a light microscope (LM), with the exception of H. magnistylus which was also studied with the aid of a scanning electron microscope (SEM) (Robbins, 1982). This article describes the morphology of H. seinhorsti as seen by SEM and gives some information on its distribution in Sri Lanka.
