Abstract
Experiments were conducted at a private farm located at Elkom Elakhdar Shebin Elkom Menoufia, and laboratory of Economic Entomology and Agricultural Zoology Department to study some biological and ecological aspects of the two spotted spider mite, Tetranychus urticae associated with four tomato and eggplant varieties during the period 2018& 2019 years.As well as to study the effect of multiple fertilization treatments on Tetranychus urticae infested four tomato varieties under field conditions During Summer and Nili cultivations. Moreover, to study the Effect of multiple application of chemical pesticides on fruit weights of four tomato varieties. In addition to study the correlation between Air temperature, Relative humidity and numbers of Tetranychus urticae on four tomato varieties during Nili cultivation 2018. Finally, to study the susceptibility of four tomato varieties to the infection with Tetranychus urticae and to study, to study the susceptibility of four egg-plant varieties to the infection with Tetranychus urticae. Incidence studies indicated that all tomato varietieswere infested with high number of Tetranychus urticae along two plantations, in addition, it could be concluded that the four tested varieties were variably infested with Tetranychus urticae during both Summer and Nili cultivation. From the obtained results it was concluded that Tetranychus urticae numbers were increased from April to May months in both treated and untreated plants with fertilizers. Also, there are significant differences between mite numbers in treated and untreated plants during May month. The results revealed that spray different chemical treatments reduced number of pests attacking tomato plants including Tetranychus urticae, increased the weights of tomato crops in all varieties , in addition elongate the harvest period of treated plants where untreated plants were dead.
