Abstract
Menoufiya Governorate, a field experiment was conducted as a completely randomized design, in spring period during the two successive season 2010 and 2011 using Kidney bean plantation. four different treatment were conducted as :Kidney bean plants alone in addition to the same plant intercropped on Mint, Fennel and Black cumin. The main crop, Kidney bean, plants were sown on 4 different spaces i.e.10, 20, 30 and 40cm. Kidney bean plants were investigated for abundance of the different stages of the two spotted spider mite Tetranychus urticae Koch :eggs, immatures and adults, as wells their predators Phytosiulus persimilis Athias-Henriot Euseius scutaulis Athias-Henriot (Family: Phytoseiidae). Inspection and investigation was conducted every two weeks: 15,30,45,60,75 and 90 days from sowing. Results showed that the mean values of T. urticae duringthegrowth period clearly increased in the space of 10cm between plants while the reverse trend occurred with the space 40cm. Results showed also, there was a significant difference between the mean numbers of eggs, immatures and adults of Tetranychus urticae Koch infesting Kedney bean in different spaces during sowing.
