Abstract : Small-scale trials were carried out in India in 1983 to determine the effectiveness of ethylene dibromide for fumigating Alphanso mangoes for export. The test insects were larvae of Dacus dorsalis. Fumigation with the compound at dosages of 20, 28 and 36 g/m³ gave 100% mortality of D. dorsalis after an exposure period of 2 h. However, the higher dosages accelerated ripening of the fruits and thus affected their keeping quality. None of the dosages showed any adverse effects on fruit flavour. On the basis of the results, the lowest dosage (20 g/m³) of ethylene dibromide is recommended for fumigation against D. dorsalis.
