Abstract

Study on ecology of plant parasitic as well as soil nematodes associated with mulberry plants was carried out in Manipur for consecutive period of three years i.e. 2006 – 2008. Sixteen different nematode genera were identified under four orders - Aphelenchida, Dorylaimida, Tylenchida and Mononchida which spread over 12 families. During the present study, Helicotylenchus spp. showed as predominant nematode genera in all studied seasons followed by Scutellonema spp. from mulberry ecosystem of Government Silkfarm, Wangbal, Thoubal District, Manipur. This may be due to the wide range physiological characteristics of the nematode group. Helicotylenchus spp. followed by Scutellonema spp., Ditylenchus spp., Caloosia spp., Criconemella spp., Aphelenchus sp., Paratylenchus spp., Basiria spp. and Tylenchus spp. are most devastating nematodes of mulberry plantation in Manipur, India.

Conclusion

Out of the sixteen genera, twelve genera showed cent percent absolute frequency in the year 2006, fourteen genera in the year 2007 and thirteen genera in the year 2008. Hemicriconemoides spp. showed lowest absolute frequency, relative frequency, relative density, relative biomass, prominence value and importance value in all the three years followed by Dorylaimellus spp. while Helicotylenchus spp. showed highest relative density, relative biomass, prominence value and importance value in all the three years. Except absolute frequency and relative frequency, relative density, relative biomass, prominence value and importance value showed remarkable shift in values for one species to another during 2006 – 2008. During the present study too, Helicotylenchus spp. showed as predominant nematode genera in all studied seasons followed by Scutellonema spp. from mulberry ecosystem of Government Silkfarm, Wangbal, Thoubal District, Manipur. This may be due to the wide range physiological char
