To know the population dynamics of potato aphids with the progress of time, data was collected from the potato field of Joydebpur. Yellow sticky traps and yellow water traps were set up in the potato field. The lowest aphid population was observed on December 19, 22 and January 03 in both traps. On the other hand, wingless aphids were counted randomly from potato leaf where the highest aphid population in January 09 and the lowest were found in February 13.
