ABSTRACT
A field study was carried out on the population dynamics of the Mediterranean fruit fly [MFF] Cemtitis capitata Wied. males in Assuit governorates [upper Egypt] during 2011/2012 and 2012/2013 seasons in mixed orchards by using Jakson trap. The obtained data revealed that the occurrence of MFF was relatively ail over the two seasons with some exceptions, The abundance of the pest was higher in the second season than that in the first one. The higher appearance of the pest was recorded on September-November in both first and second seasons. Temperature had significant negative correlation [r=0.105] in the first season and insignificant negative correlation [r=0.076] in the first and second seasons, respectively. However, R.H.% had high significant positive [r=0.451] and insignificant positive [r=0.203] in the first and second seasons, respectively. Results obtained could be exploited in management of this insect pest especially, in the control programs
