Abstract

ABSTRACT Piesmopoda obliquifasciella (Hamps) has been recorded damaging Cassia fistula severely at Peshawar. A survey was carried out to determine the number of sample per tree for accurate and precise damage assessment. A maximum of 39.06 &plusmn 6.10 and minimum of 25.88 &plusmn 2.58 percent damage was recorded at 2-3.5 and 4-5 meters tree height, respectively. On western, eastern, and northern side of crown, difference in damage at the two tree heights was significant (P< 0.05), while it was insignificant on southern side. Similarly, the overall damage on the four directions differed significantly. The highest (36.49%) and the lowest (31.88%) overall damage was recorded on western followed by eastern (34.96%, 31.81%), southern (30.93%, 29.67%) and northern (30.29%, 28.95%) sides.
