dc.description.abstractABSTRACT The present investigations were carried out during the period of research on “Studies on predaceous nematode (Order : Mononchida Jairajpuri, 1969) associated with flower crops under protected cultivation in district Solan (Himachal Pradesh)”. Four mononchids viz; Mylonchulus (M. brachyuris), Iotonchus (I. monhystera), Mononchus (M. truncatus) and Clarkus (C. papillatus) were found harbouring the rhizosphere of flower crops (carnation, rose and chrysanthemum), along with plant parasitic nematodes namely; Meloidogyne (M. incognita J2), Helicotylenchus (H. dihystera), Tylenchorhynchus (T. mashhoodi), Pratylenchus (P. coffeae) and Paratylenchus (P. curvitatus). Among the mononchids, maximum incidence was of Mononchus (in 35%), followed by Mylonchulus (33%), Iotonchus (25%) and Clarkus (2%). Highest population was recorded for the Mylonchulus (400/ 200 cc soil), followed by the Iotonchus and the Clarkus (180) while it remained minimum for the Mononchus (120). With highest average population of 54.90, Mylonchulus dominance the other mononchids. There was recorded –ve correlation between predatory and plant parasitic nematode populations in all the localities surveyed/ sampled. Although, overall results showed positive correlation between mononchid population and edaphic factors viz; pH, moisture, temperature and organic carbon, on the nematode population was more pronounced due to moisture and organic carbon. Too acidic soils (within a pH range of 3.69-5.73) were found free from the mononchids , while proportionate increase in their populations were observed within a pH range of 5.78-6.58. However, after 7.0 pH there was again recorded gradual decrease in the population.en_US
