The bark beetle, Hypocryphalus mangiferae has been consistently found in Pakistan on mango trees suffering sudden death disease. In this study we estimated the efficiency of different monitoring techniques, dispersal activity and dispersal distance of H. mangiferae. The response of the beetle towards coloured sticky traps and ethanol baited traps was almost negligible whereas, the tree-log traps proved to be the most efficient monitoring methods in the orchards. The peak dispersal activity in terms of number of holes was observed in the month of May by using tree-log traps. The activity of H mangiferae was positively related with temperature and negatively related with relative humidity. The dispersal distance of bark beetle was measured with the help of tree log traps on 6 different distances. The maximum attraction was recorded at 5 meters from the source tree which gradually decreased up to 60 meters. Based on these findings, we conclude that monitoring dispersal activity with tree log traps can be an appropriate part of integrated management of mango bark beetles.
