| Abstract | ||||
| The trials were carried out on cucumber plants during spring plantation of 2017 season the Faculty of Agriculture Farm, Assiut University to survey the mite species inhabiting cucumber plants and the associated predators, and to evaluate certain acaricides against the most abundant one, Tetranychus urticae Koch. In general, 11 arthropod species belong to 9 families and 4 orders, other than predatory true spiders were surveyed from cucumber plants. The mite species inhabiting cucumber plants were Polyphagotarsonemus latus (Banks), Tetranychus urticae Koch, Tetranychus cucurbitcearum (Sayed), Pronematus sp < em>. and Tydes sp < strong>. and five predatory species. The pesticides used in the experiment were thiamethoxam 20% WP, acetamiprid 20%, SP dinotefuran 20% SC, methomyl 90% SP, and buprofezin 25% SC. The high percentage reduction was 95.38 for buprofezin after ten days. The highest average of reducing T. urticae was for methomyl (85.18) and buprofezin 25% (84.08), while the lowest average of reducing T. urticae was for acetamiprid (42.66). The general reduction of T. urticae was 73.46 and 75.84 for thiamethoxam and for dinotefuran, respectively. Since these pesticides are used on all sucking pests, the experiment gave good results to control T. urticae associated with other harmful pests. | ||||
