Abstract

Field tests were carried out in 2005-2006 growing season to determine the efficacy of Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metsch.) Sorokin, mineral oil and carbamate insecticide, carbosulfan on Tetranychus urticae at El-Arish, North Sinai Governorate.
Results showed that no significant differences of mite individuals and reduction of infestation appeared on tomato and eggplant between entomogenous fungi and mineral oil plants, while the difference was significant between treated plots and the untreated one. In watermelon cultivation, clear difference in mite individuals shown between mineral oil and bioranza, as well as, between mineral oil and carbosulfan after 7 days post-application. Slight difference in reduction percentage of mite infestation appeared between tested compounds. Reduction percentages of mite were 71.34, 77.10, 78.38 and 84.20% for biovar, bioranza, mineral oil and carbosulfan, respectively. Carbosulfan was less effective than entomogenous fungi and mineral oil in reducing the individuals of mites on qantalup plants at the different time intervals post-spray. There were no significant differences in natural enemies population on tomato between biovar, bioranza and mineral oil treated and untreated plots at different time intervals post-spray. The seasonal average of natural enemies in watermelon was not significantly differ between biovar, bioranza treated area and the untreated one. While mineral oil revealed the highest population of natural enemies, carbosulfan gave the lowest number and differed significantly with all treated and untreated plots.
