| dc.description.abstract | Mango (Mangifera indica L.) is grown commercially on a great scale throughout the world's tropical and subtropical lowland areas. It contains a lot of carbohydrates, potassium, and phosphorus and is a strong source of vitamins A and C and also it is the main fruit crop grown in western Ethiopia's Beneshangul Gumuz Region for family use and sale. However, a number of insect pest prey on this significant crop, with the white mango scale (WMS) insect, Aulacaspis tubercularis Newstead, being one of the most destructive. WMS damage causes significant yield losses due to defoliation, fruit abortion, poor flowering and drying of twigs, and fruit rejection due to blemish marks on fruits. As a result, a study was conducted in Aberamo Woreda, Western Ethiopia, to determine the distribution, prevalence, and Management options for the White Mango Scale. In ten Kebele of Aberamo Woreda, the study was carried out between September 2022 and June 2023. Preliminary Survey on the prevalence of white mango scale on mango trees was collected from the Office of Agriculture of Assosa Zone. Data sheet was prepared to record the presence or absence of pest incidence and pest density. After the existence of the pest confirmed, the level of leaf infestation was measured by using a hand lens and visual estimation of the proportion of infested leaves. From each Kebele Randomly select five mango trees and from each trees ten leaves was taken for eight consecutive months and eighty (80) people selected for questionnaire from ten Kebeles which means eight (8) people was selected from each Kebele. The acquired data were then analyzed using SPSS software. The research findings revealed that farmers noted a high infestation of the pest, which is a new pest that is specifically transferred by planting materials, due to the nature of the mango tree's massive size and backyard farm production made management difficult, resulting in output decline. A white mango scale insect pest infestation was much greater in the study location, and it first affects the plant's leaf, then the stem. The fruit's commercialization is also severely harmed because it loses its original color. Infestation status varied significantly throughout study months, with the lowest and greatest records occurring in December and April, respectively. The infestation became serious due to ideal rain fall, relative humidity, and mismanaged mango orchard conditions. As a result, it is advised to conduct regular inspections and monitoring, establish a robust domestic quarantine, explore resistant mango varieties, and conduct further screening of IPM suitable insecticides in order to provide a sustainable management approach for the white mango scales insect pest. | |
