The results based on certain biological aspects showed that plum branches were the more attractiveness to Scolytus amygdali Guér beetles, while the pear branches were the least attractiveness. The beetles rearing on plum constructed the longest egg gallery, deposited the highest number of eggs and gave the highest number of progeny, while the reared on pear built the shortest length of egg gallery, laid the least number of eggs and produced the least progeny. The longest duration of generation occurred for the beetles reared on apple branches, while that reared on pear and plum appeared the shortest duration. On the other hand, the beetles reared on peach appeared the longest period of adult emergence, while the shortest period occurred on apple branches.
