| Abstract | ||||
| This study aimed to evaluate the performance of some mango cultivars in response to the striped mealybug, Ferrisia virgata (Hemiptera: Pseudococcidae) infestation in Kom Omboo region, Aswan Governorate, southern Egypt, during 2022/2023 and 2023/2024 seasons. The results showed that F. virgata populations were present on all mango cultivars throughout the year. The susceptibility of these cultivars to F. virgata varied. Zebda mango cultivar had the highest number of mealybugs and was classified as highly susceptible to F. virgata infestation. Goleck and Hindi Bisinnara cultivars were found to be susceptible while Ewaise, Sediek, and Taimour cultivars showed relative resistance during both seasons. However, the Taimour cultivar showed the lowest estimates of F. virgata infestation during both seasons, so in the areas where mealybug infestations are high; this mango variety should be considered. Results reveal that the Zebda cultivar had the highest values of mean numbers of F. virgata, population growth rate, quantity ratio, attraction index, crowding density, relative abundance establishment rate, and prevalence index. All these parameters indicated that this cultivar was preferred by F. virgata individuals compared to the other mango cultivars during both seasons. In contrast, the non-preference index was significantly higher in the Taimour cultivar compared to other tested cultivars. A new IPM approach for the control of F. virgata may be developed with the aid of this data. | ||||
