Abstract : Aeromycoflora of mango store houses was studied by using Volumetric Tilak Air sampler for a period of two consecutive years. A total of 42 fungal spore types were identified. The predominant spore types included Cladosporium, Penicillium, Pseudotorula, Rhizopus, Aspergillus, Alternaria, Nigrospora, Fusarium, Curvularia and Helminthospore. Simultaneously, a systematic survey of post-harvest diseases of mango storehouses and fruit market was undertaken at weekly intervals for two consecutive years. The investigation showed that there were some relationship between the airspora of storage houses and the prevalence of fruit rots. Firstly there were some fungi, which were extensively prevalent both in the air and on spoiled fruits, e.g. Cladosporium, Penicillium, Curvularia, Fusarium, Helminthosporium, Nigrospora and Aspergillus. Secondly, those fungi which were more prevalent in the air but caused few rots e.g. Alternaria, Fusarium, Pseudotorula and Curvularia. Thirdly, the fungi that were less prevalent in the air but caused considerable fruit rot e.g. Aspergillus niger, Colletotrichum gleosporioides, Botrydiplodia theobromae and Botrytis cinera. Eleven fungi were isolated from spoiled mango fruits and found to be associated with post-harvest diseases of mango causing both quantitative and qualitative losses.
