Abstract
Results showed that ,it has been ahigh significant differences between the Acaricides and mortality percentage that occurred on two spotted mites . Sorbin and medamic gave the highest mortality persentages for the nymphal stage within 24 hours of treatment reaching 83.6 and 79,5% respectively. Gather high after 72 hours with95.2 and 91.4% respectively while mortality percentage for adult female reaching 88.5,86,7and 83,9 %after treatment with medamic, . Sorbin and respectively.Super acid was the lowest with 65,2% mortality percentage. Also Result showed significant differences between alkolid compound for Citrullus colocynthis and phenolic compound on the mortality percentage for the nymphal stage reaching49.05 ,53.5 ,68.2% but not after 72 hours .
