| Abstract/Contents: | "A new diplogasterid species, Mononchoides sp., was isolated from soil at The Turfgrass Farm. The predatory potential of Mononchoides sp. was assessed in terms of predation, feeding, predator strike rate and prey preference, and prey resistance and susceptibility to predation. Experiments to date suggest that this nematode possesses attributes useful for biocontrol. Prey preference and feeding behavior of Mononchoides sp. was studied using 11 phytoparasitic nematode species as prey. Monochoides sp. showed preference for different species of prey when tested in a no choice and choice experiments. Meloidogyne incognita and Helicotylenchus. mothi were highly susceptible (PS = 91.5-93.5%) to predation as they were most attacked (SR = 92-94%) and preferred by predators (78.0-84.0% preference). Predators showed low preference for Helicotylenchus indicus (Hel. indicus) (28.0%) and 0% for Hoplolaimus indicus (Hop. indicus) and Hemicriconemoides mangifeare when tested with single prey species. All prey, except Xiphinema americanum and Pratrichodorus trichodorus, were accepted more than they were rejected in ten combinations. Preference for M. incognita (mean prey accepted = 39.6%) over others ranged between 04 to 88% with 0% rejection. Coefficient of preference was highest for M. incognita (1.0), minimal for Hel. indicus (-0.57) and zero for Hop. indicus and H. mangiferae. Degree of prey suseptibility determined predator feeding after prey wounding, highest being for M. incognita and H. mothi (PF = 100%), moderate for Tylenchorhynchus mashoodi, Longidorus attenuatus, X. americanum and P. Christie (PF = 60-87.5) and minimal for Hel. indicus (PF = 13.3%). Longest feeding duration was recorded on L. attenuatus (108.8 m; range: 90-121m) and shortest on M. incognita (33.5 m; 28-38m). Temperature and prey density governed predator's feeding activities e.g., search duration was shortest with 150-225 prey at 20-30°C. Predators killed and fewer prey under similar conditions. Temperature and prey density extremes inhibited predator activities including aggregation duration at the feeding sites." |
