| Abstract | ||
| Field study was conducted to evaluate the efficiency of three cases in applied Bait Application Technique (SAT) as area-wide control proqrarns against Medfly Ceratitis capitata Wied. in KhanYunis And Rafah Governorates. The first case was real partial bait spraying BAT as traditional treatments. the second was high BAT frequency treatments programs (10-20 days around) in Valencia orange and guava groves and the third was low BAT frequency treatments programs (more than 30 days round) also in above fruit trees during two successive seasons; 2002 & 2003. Investigation was conducted on all agricultural areas treated traditional BAT treatments: two guava groves for every high and low BAT (requency and two Valencia orange groves also for every high and low SAT frequency treatments program in both seasons. Jackson traps with the male attractant trimedlure were used in all groves study for monitoring the population fluctuation under three cases used of BAT. The capture males per trap Iday (CTO) for 36 dates of inspection In season was considered as indicator for efficiency three cases used of BAT against C. capitata and to estimate Medfly population in fields study. Results show exist statistically differences mean number CTD of C.capitata in three cases BAT used (traditional. high, low frequency) in all groves. guava and Valencia. While this differences not exist between two seasons 2002 and 2003 for all groves (traditional treatments) In both Governorates. However the data indicated that high frequency BAT (10-20 days round) in g:lava and Valencia orange groves reduce significantly the population of Medfly comparison with the low BAT frequency (more then 30 days round) in guava and Valencia groves. In seasons 2002 & 2003, eTO of C. cap < /em>itala ranged between 2.54.2.47 respectively in all groves treated first case BAT treatment (traditional). The grand mean of 36 inspection every season in guava groves treated high and low BAT frequency the eTO of Medfly was ranged 3.37-4.32 , 7.12-7.5 respectively. In Valencia orange groves the grand mean of 36 inspection every season treated high and low BAT frequency the CTO of C. capitata was ranged 3.60-3.56 . 3.82-7.12 respectively. Relationship between fruil availability of host fruit, climatic condition and Medfly numbers have been observed in this study. Percentages fruit infestation in guava ranged between 25 % 10 48% while the percentage infestation in Valencia orange ranged between 0.0% to 56.9% in KhanYunis and Rafah during harvesting periods in 2002 & 2003 seasons. | ||
