Abstract
Biological control of Tetranychus urticae Koch different stages on two cucumber cultivars (Sahm & Heikal) grown inplastic houses in Nubaria District, Beheira Governorate, during 2004&2005 seasons was studied. Four predatorphytoseiid mites; Phytoseiulus macropilis (Banks), Neoseiulus californicus (McG.), N. cucumeris (Oudemans), and N.zaheri (Yousef and El-Borolossy) were used against T. urticae different stages. N. californicus and P. macropilis gavethe highest reduction percentages of T. urticae different stages (97.36 & 97.51 % adults; 98.49 & 98.45% immaturesand 99.36& 98.59% eggs) in Sahm cultivar, while in Heikal cultivar the percentages were 87.14 & 92.50 %; 98.50 &97.38 % and 97.87&97.85%, respectively during 2004. Similar results were obtained, during 2005. Chemical control byspraying the two compounds Vertemic & Ortus proved that Vertemic was the best in reducing T. urticae different stagesby 89.55, 95.37 & 94.00% of the aforementioned successive prey stages. Integrated pest control, showed that releasingN. californicus and P. macropilis after spraying Vertemic gave in general the high reduction of T. urticae differentstages but less than Vertemic alone. However using the two predators alone and not integrated with acaricides gave thehighest reduction percentages.
