Abstract

The predatory mite, Neosakflus cucumeris (Cud.) was released to control the two-spotted spider mite, Tetranychus urticae Koch on cucumber field at Todc district, Qualubia Governorate. N. coroner's was released at a rate 5 Individuals/bit in the treated area. The percent reduction of the mite pest reached 98.70% after two months of release with level of infestation of the mite pest averaged 0.72 mite/leaf compared with 50.92 individuals of mite pest/leaf in the control area. These results indicated the possibility of this predator to be established under the Egyptian conditions and can be use as a biocontrol agent to control this mite pest on cucumber plant conditions. We would like to add that this predator mite, recently import from Koppert Center of producing natural enemies from Holland. We aim to produce product free of pesticides and adamizing this predator species in Egypt.
