Abstract
Tropical and sub-tropical fruits make a significant direct contribution to the subsistence of small–scale farmers by providing locally generate nutritious food that is often available when other agricultural crops have not yet been harvested.
Mango (Mangifera indica L) is the third most important fruit crop in the tropics and sub-tropics following Citrus and Banana. It is consumed as a fresh fruit and different form of preparations for its high contents of sugars, vitamins, minerals, protein and known to play a vital role in export and import business. Mango suffers from several diseases and insect pests and its trunk, branches, leaves, petiole, flower and fruit are attacked at all stages of its development It spread and has become a threat to mango production in almost all Oromia zones of the districs and the kebeles and affected economic benefits of mango farmers. The objectives of this study was to assess the status and prevalence of white mango scales infestation, distribution and the existing capacities to control the pest at Wayoseko kebele of AlgeSachi district of Illuababora zone of Oromia Regional State. From the current study, white mango scale was the crucial mango production limiting factor in Illuababora zone of AlgeSachi District because of its high rate of dispersal in all mango plantations in the vicinity. The data were collected randomly from January 10/5/2011 to June 10/10/2011 from the orchard of Green focus through observation, interview and Questionnaire which distributed for purposefully sampled population. The result of study showed that high population peaks of WMS was recorded and distributed from its original point with high and very high infestations across district and kebeles in km. Most mango grower farmers used cultural methods to control the pests. The current study concluded that WMS was spreading very fast across district and kebeles from it first locus, and it is recommended that the infestation on mango can be reduced by the use of farmer’s indigenous knowledge of pest management practice.
