Subject(s): Online resources: In: Bulletin of The Entomological Society of Egypt (A.R.E.), Economic Series 2005.v.31Summary: The two-spotted spider mite, Tetranychus urticae Koch is one of most serious sucking pests, which reduce plant ability to build carbohydrate resulting in reduction of total yield. T. urticae infests a very wide range of hosts. It was recorded by Abd ElRahman (1996) on 60 economic plant species varied among fiber crops, vegetables, fruits, medical plants, ornamental plants and cereal crops. The industry of chemicals locused primarily On toxic chemicals over the past 50 years, neglecting the fact that plants have their own self defense system against external aggressions. Recent scientific advances in chemical ecology have highlighted a number of natural compounds. Momen et al. (2001) found that the essential oils of Mentha virdis L. and Mentha piperita L. had repellent effect and reduced the total number of eggs laid by T. urticae.
