The potential use of two predacious mites, Parasitus fimetorum (Berlese 1904) and Macrocheles muscaedomesticae (Scopoli 1972), for controlling the root knot nematode, Meloidogyne javanica Treub 1885 was evaluated under laboratory and semi-field conditions. Obtained results revealed that the 2 predators significantly reduced the root knot nematode numbers. In addition, the highest reduction percentage (57.24%) in nematode juveniles was recorded at the treatment of (1000 nematode + 10 mites). For M. muscaedomesticae, the highest mortality percentage (50.83%) in nematode juveniles was recorded at the treatment of (1000 nematode + 50 mites), followed by (1000 nematodes + 20 mites) 48.88%, while the treatment of (1000 nematode + 10 mites) gave (47.13%). The combination of the 2 mite species (1000 nematodes + 50 mites/species) caused the highest mortality percentages in nematode juveniles (69.29%), followed by (1000 nematodes + 20 mite/species) 50.51% and the treatment of (1000 nematode + 10 mite/species) (37.66%). At the pot experiments, the highest overall mortality percentage in M. javanica juveniles was recorded at the treatment of P. fimetorum + M. muscaedomesticae giving (57.07%), followed by the treatment of P. fimetorum (39.17%), and then, by M. muscaedomesticae alone that recorded only (17.47%). In conclusion, predacious mites can be partially considered a control tool of the parasitic nematodes.

作为根结线虫（Meloidogyne javanica Treub ）的天然捕食者的寄生虫fimetorum和大螯虾muscaedomesticae（A螨：Parasitidae，Macrochelidae）

在实验室和半田间条件下，评估了两种珍贵的螨虫（寄生虫）（Berlese，1904年）和Macrocheles muscaedomesticae（Scopoli，1972年），用于控制根结线虫（Meloidogyne javanica Treub 1885）。获得的结果表明，这两种捕食者显着减少了根结线虫的数量。此外，在处理（1000根线虫+ 10螨）时，线虫幼虫的最高减少率（57.24％）被记录下来。对于M. muscaedomesticae，线虫幼虫的最高死亡率（50.83％）记录在（1000线虫+ 50螨）的治疗中，其次是（1000线虫+ 20螨）48.88％，而（1000线虫+得到10螨）（47.13％）。两种螨类（1000种线虫+ 50种螨/物种）的结合导致线虫幼虫的死亡率最高（69.29％），其次是（1000种线虫+ 20种螨/物种）50.51％的治疗和（1000种线虫+ 10种/物种）（37.66％）。在盆栽试验中，在给予麻省分枝杆菌+ muscaedomesticae给予（57.07％）的治疗下，爪哇麻省分枝幼虫的最高总体死亡率百分比最高（39.17％），然后，仅由M. muscaedomesticae所记录（17.47％）。总之，可以将捕食的螨虫部分地视为寄生线虫的控制工具。M. javanica幼虫的总死亡率最高，记录是治疗给予费氏疟原虫+ muscaedomesticae（57.07％），其次是治疗费氏疟原虫（39.17％），然后是单独的muscaedomesticae仅记录（17.47％）。总之，可以将捕食的螨虫部分地视为寄生线虫的控制工具。M. javanica幼虫的总死亡率最高，记录是治疗给予费氏疟原虫+ muscaedomesticae（57.07％），其次是治疗费氏疟原虫（39.17％），然后是单独的muscaedomesticae仅记录（17.47％）。总之，可以将捕食的螨虫部分地视为寄生线虫的控制工具。
