Testing the Ability of Ips Typographus L. Females to Develop New Maternal Galleries in Lab Conditions

Abstract

We report the preliminary results regarding the capacity of Ips typographus females to develop new maternal galleries in controlled conditions of temperature, humidity, and 24L:0D and 16L:8D photoperiod. Despite the fact that the number of entries was higher on the logs permanently exposed to light, other parameters, such as the success in the development of new maternal galleries, the length of the maternal galleries, and the density of the maternal galleries with eggs, were higher in the case of 16L:8D photoperiodic regime, but no significant differences were found.
