| Abstract | ||||
| The phytophagous mites are common pests in agricultural systems, causing in many cases greater economic losses than other any pests. The population fluctuation of some phytophagous and predaceous mites were determined for two successive seasons, 2014/2015 and 2015/2016 on (eggplant) at Giza, Governorate, and these mite was with relation to some weather factors (maximum, minimum temperature and relative humidity), and the predaceous mites. The population fluctuation of the phytophagous and predaceous mites was not significant positive correlation between both mites and weather temperature (Max. and Min. Temp.) during the two seasons, while for the relative humidity the correlation was negative with the phytophagous and predaceous mites during the two seasons. The predaceous mites, Euseius scutalis, Typhlodromips swirskii and Pronematus ubiquitus were found in relatively few numbers during January and the following months. A highly significant positive correlation was found between Tetranychidae, Eriophyidae and weather temperature (Max. and Min. Temp.). While, significant negative correlation was confirmed between mites infestation and relative humidity. Highly significant negative correlation was occurred between Tarsonemus smithi and weather temperature, while it was a highly positive correlation between mite infestation and relative humidity. The effect of maximum and minimum temperature on the predaceous mites showed significant effective, positive correlation between both the mites and weather temperature, while a negative correlation was confirmed between the predaceous mites infestation and relative humidity on eggplant during the two studied seasons. | ||||
