| Abstract | ||||
| Pot experiments were carried out to investigate the predation efficiency of Macrocheles matrius (Hull) on the two parasitic nematode species infected sour orange, i.e. Citrus nematode, Tylenchulus semipenetrans and Lesion nematode, Pratylenchus penetrans under greenhouse conditions. All applied treatments significantly reduced soil nematode population of T. semipenetrans and P. penetrans. Predation efficiency of M. matrius predator on T. semipenetrans was higher than that occurred on P. penetrans. Treatment of M. matrius gave the highest reduction percentage (77.5%) on T. semipenetrans nematode compared with (76.9%) at the treatment of the nematicide, Carbofuran. In addition, effectiveness of the previous treatments gave a better enhancement of various citrus growth parameters such as: plant height (135.0 cm) ; shoot weight (86.5 g) and root weight (23.5 g) with increment for each by (+64.6; +37.7 and +95.8 %) compared with control values, respectively.Macrocheles matrius gave ahigher reduction percentage than the nematicide (Carbofuran) especially againstT. semipenetrans. So, it could be encouraging the use of the predator mites as theMacrochelids group in the biological control programs of plant-parasitic nematode. | ||||
