Abstract
The peach fruit fly Bactrocera zonata, is a harmful insect that infests various fruit crops and vegetables worldwide, including Egypt. Its presence leads to significant damages and losses. To minimize the negative impact of pesticide residues on human health and the environment, a study was conducted to examine the seasonal behavior of Bactrocera zonata on navel orange trees. This investigation involved the utilization of sex attractants and the monitoring of fruit samples. The research was conducted over two consecutive seasons, namely 2020 and 2021. By utilizing sex attractants, pheromone (mass trapping) it was discovered that the number of male Bactrocera zonata captured and infested increased during the Autumn period, specifically in October, in both seasons. Additionally, it was observed that Bactrocera zonata males exhibited a single peak of activity each season. Fruit samples were monitored to assess fruit infestation, and it was found that infestation was positively correlated with the maturity of the fruits. The weekly count of males captured in the fly traps, along with the infestation rate of this pest, indicated that these traps could serve as a useful tool for predicting the infestation rates of Bactrocera zonata in their host fruits. Conclusion The implementation of mass trapping techniques utilizing pheromone-based tools will result in a reduction of infestation by the end of the second season of 2021.
