| Abstract | ||||
| The two-spotted spider mite, Tetranychus urticae Koch (Acari; Tetranychidae), is one of the most important pest worldwide. It is a major pest of crops, orchard trees, ornamental, medicinal plant and vegetable crops .Therefore, new approaches in mites control were applied, particularly the use of plant extracts that have received recently considerable attention. Many trials all over the world have succeeded through the use of bio-pesticides in controlling mite pests in different orchards and field crops. Members of the family Phytoseiidae are the most effective and wide spread predators of injurious plant-feeding mites. The twospotted spider mite develops a resistance to most acaricides after prolonged use. Nevertheless, acaricides are used on a large scale to control phytophagous mites, thus affecting the population of phytoseiid mites Tawfiq and Isra (2013). There were side effects of the acaricides on the abundance of its associated natural enemies and effect on the biological aspects of the most important predaceous mites (Euseius scutalis Athias-Henriot). Some of the most common problems encountered during biological control for two spotted spider mites first, improper timing of the release ofpredator, so effectively use biological control is when the pests are at relatively low levels. Second, cultural or chemical practices which adversely affect the natural enemy. | ||||
