Abstract

 The efficacy of three bio-acaricides i.e. Vapcomic 1.8 % EC, Ortus 5 % SC and Bioranza 10 % WP using the recommended field rate were evaluated against the two-spotted spider mite, Tetranychus urticae Koch and their effect on the dominant predaceous insects and mites in cotton fields was also studied. The field experiments were carried out at Zagazig district, Sharkia Governorate, on cotton seedling (early season) and flowering stage (late season) during both two cotton seasons 2005 and 2006. The obtained results cleared that, Vapcomic was the highest toxicity on T. urticae and predators during both seasons followed by Ortus and Bioranza. In cotton seedling stage the average reduction percentages of T. urticae were 86.11, 84.89 and 54.47%, during season 2005, for Vapcomic, Ortus and Bioranza, respectively, 94.98, 84.34 and 55.28 % during season 2006, respectively. In flowering stage the average reduction percentages of T. urticae were 92.46, 85.29 and 56.11 % during first season, for above compounds respectively, 97.8, 86.55 and 54.53 % during the second season, respectively. As for predators, the same trend of toxicity was achieved from foregoing results. Data, could be detected that Vapcomic was more effective against predators than Ortus and Bioranza, during both seasons. The percent reduction of predators recorded 85.05, 61.97 and 34.3 % during cotton seedling stage for season 2005, respectively, 55.22, 45.32 and 32.75 % during season 2006, respectively. In the flowering stage the average percent reduction of predators recorded 67.97, 52.76 and 46.40 % during season 2005, respectively, 50.3, 23.92 and 17.72 % during season 2006, respectively.
