Drawing of the Eastern Mediterranean (Israel, Palestine, Jordan and Egypt) showing the location of the five sampling sites.
Fig 2.
Profiles of monthly mean numbers of Bactrocera oleae flies/trap/day (FTD) between February 2007 and November 2012 for each site. The mean blue line has been adjusted with a loess function (weighted least square) with a 0.5 span and confidence bands with a 0.95 level of standard error. Ticks along the x-axis indicate January of the corresponding year.
Fig 3.
Monthly rate of population change (Rt) of Bactrocera oleae at each site. Points represent the means, boxes represent ± 1 SE and whiskers represent ± 1 SD.

Descriptive statistics for olive fly captures in the five locations in the Eastern Mediterranean region (see Fig 1).
Fig 4.
Autocorrelation functions (ACF, blue) and partial rate correlation functions (PRCF, green) on the de-trended rate of population change (Rt) of the olive fly in the Eastern Mediterranean region. Broken red lines depict the 95% confidence interval for the correlations.

Endogenous and exogenous influences on the rate of population change.
Direct endogenous (logMFTt-1) and exogenous (nLST; NAOi; fruit availability, 0: absent, 1: present) influences on the rate of change in the olive fly population (Rt) in Lahav. Observed points are depicted in blue. The fitted line is drawn in green, according to the selected generalized-least-squares model indicating partial regressions (Table 2).
