Abstract
Seasonal abundance of C.dorsata beetle on mango trees and the influence of certain climatic factors on the occurrence of insect were studied during 1997 and 1998. The beetle occurred throughout the pe­riod from the 2nd half of March until the 1st half of October. Two peaks of beetle activity were recorded annually during the 1st half of May and the 2nd half of June 1997 and during the 1st half of April and the 1st half of August 1998. Statistical analysis showed significant correlation between the number of emerged beetles and each of Max. Temp., Min. Temp. and R.H.% during the 1st occurrence 1997, while the correlation was only significnt with Max. Temp. and Min. Temp. during the 2nd occurrence 1998. On the other hand, tested climatic factors not show any influence on the number of emerged beetles during the 2nd occurrence 1997 and the 1st occurrence 1998.
