Testing the Preferences of Ipidae for Various Pines in the Forest District of Dumitresti

Abstract

The current paper describes the results obtained while comparing the preferences of the bark beetles for three different species of pines. This experiment was performed for the first time in our country and was made in the Forest District of Dumitreşti where the bark beetles are constantly present. Thus we found new data linked to the dynamics of the flight, the success of the attacks, the preference of bark beetles for a certain host, the variation of the attack density, the variation of the average length of the egg galleries for each host and species of Ipidae.
