| Abstract | ||||
| The peach fruit fly (PFF), Bactrocera zonata (Saunders), is one of the most destructive pest species in the world. The objective of this study is to manage the pest in the field while elucidating the frequency and abundance of flies on mango and citrus orchards utilizing Jackson sticky traps during 2021/2022 and 2022/2023 seasons in relation to the prevailing weather parameters. The results revealed that population increase of peach fruit fly starts from April onwards and the maximum population is recorded during May-October with a major peak in August. The highest activity rate of peach fly was recording during 2021/2022 season than 2022/2023 season for both citrus and mango orchards. The highest population was recorded on the mango orchard reached (376 and 360 insects) in August 2021/2022 and 2022/2023 seasons, respectively. In the citrus orchard, the highest fly activity rate was recorded (242 and 235 insects) during the November, 2021/2022 and October, 2022/2023 seasons, respectively. Data showed that, Spinosad plus alpha-1 was recorded the higher reduction in the mean numbers of captured flies through three weeks of treatment.In the first farm, (Al-Saada Island), the percent reduction in the mean numbers of captured flies treated with spinosad plusalpha-1, alpha-1, indoxacarb plus alpha-1 plus clorfenapyr and spinosad was recorded 82.46, 79.62, 70.14 and 69.43%, respectively. While the second farm (Al-Qurain) were 83.28, 74.92, 67.80 and 60.37%, respectively. Conclusively, Bactrocera zonata (Saunders), often known as the peach fruit fly (PFF), is a highly destructive insect found worldwide, particularly of fruit.We advise that control operations start in April and continue until the fruits are fully ripe, taking into account the recommended safety periods. Due to the insect's great ability to develop resistance to insecticideswe recommend that, not using insecticides alone more than once and using them in mixtures. | ||||
