Relationships of Species of Helicotylenchus with Taxonomic Groupings of Host Plants
Journal Title: Journal of Plant Science and Research - Year 2016, Vol 3, Issue 1
Abstract
Spiral nematode, Helicotylenchus (Tylenchida : Hoplolaimidae), mostly act as ectoparasite on diverse group of plants. Studies on 33 species of spiral nematodes revealed that 7 species were host specific in monocotyledons, 6 in dicotyledons-lignosae and 5 in dicotyledons-herbaceae, and were designated as monophagous. H. digonicus, H. dihystera, H. microlobus H. multicinctus and H. psedorobustus parasitize large number of host species and were classified as polyphagous. Host affinity to taxonomic groups was species specific. Nevertheless, a general preference was more towards dicotyledons. Some species were able to parasitize host species from most primitive families to advanced ones and some included gymnosperms also in their host range. This study will help in selecting crops in particular nich or endemic areas and contribute in decision making process for their management.
