The studies were carried out to isolate the mango quick decline fungi from mango bark beetle, Hypocryphalus mangiferae S. collected from mango orchards of Nawab pur, Lutfabad and Faiz pur bhatian, Multan, Pakistan. Different life stages of H. mangiferae were collected from diseased mango trees and fungal isolations were carried out from each stage as well as from different body parts (head, thorax and abdomen) of adult. Five types of fungi i.e. Ceratocystis fimbriata, Lasiodiplodia theobromae, Fusarium sp., Alternaria sp. and Aspergillus sp. were frequently isolated from life stages and body parts of H. mangiferae. However, their isolation frequency varied in different life stages and body parts. The consistent isolation of these fungi suggests their close association with H. mangiferae but the exact symbiotic relation between them need to be investigated.
