| Abstract | ||||
| Experiments conducted in table grape orchard, variety crimson (late-ripening, red seedless table grape variety) at Nubaria-district, Beheira-Governorate-Egypt, during blooming and fruiting periods (May to October) of seasons, 2019-2020. Results showed that,medfly males were most active during morning 7:00-10:00am (0.98. and 0.905 males/trap/hour in 1st and 2nd seasons, respectively) than other day. Lowest trapped males number (0.012 and 0.028 males/trap/hour in 1st and 2nd seasons, respectively) recorded during period from 19.00pm-7.00am of next-day (night-hours). Results cleared that, high traps captured more male fly's number than low and appropriate trap height for medfly males in grape orchard at 2.5m above ground (0.451 and 0.524 males/trap/hour in 1st and 2nd season, respectively). Minimum trap catch recorded in traps which kept at height 0.5m above ground (0.216 and 0.201 males/trap/hour in 1st and 2nd season, respectively). Infestation grape bunches and berries by medfly studied in relation to adult flies trapping by McPhail traps. Proportion of infested grape bunches and berries increased as grapes maturity, harvest date approached and as increasing of C. capitata population. Linear regression equations fitted worked out and coefficient determination (R2) mostly showed higher indication, hence predictions and forewarning infestation rate by pheromone traps were reliable. Control results showed, significant differences between treatments and control and most effective was spinosad (conserve) insecticide. | ||||
