2.3 Assessment of Population density of A. pongamiae
The galled leaves collected from the field were cut in to
six pieces with a sharp blade and individual piece was
subjected to observation under LEICA optical microscope
and the number of different stages of the gall mite were
counted and recorded (Fig.2). In order to correlate the
impact of physical factors like the temperature, RH and
rain fall on the population density of the mite and the % of
damage induced, Pearson correlation was followed.
