Obiettivo METHODS WILL BE DEVELOPED TO : - SUPPRESS ATTACK AND REPRODUCTION OF BARK BEETLES IN CONIFER STEMS AND LOGS BY THE USE OF PHEROMONE AND OTHER SUBSTANCES, BY TRAPPING AND OTHER METHODS, - REDUCE THE ATTRACTIVENESS OF CONIFER STEMS TO BARK BEETLES, - IMPROVE THE EFFECTIVENESS OF BARK BEETLE TRAPS. ATTENTION WILL BE PAID TO THE DEVELOPMENT OF METHODS FOR ESTIMATING BARK BEETLE POPULATIONS. THE STUDIES WILL PRIMARILY CONCERN NORWAY SPRUCE (PICEA ABIES), WITH SCOTS PINE (PINUS SYLVESTRIS) GIVEN SECONDARY CONSIDERATION. INSECT SPECIES TO BE INCLUDED IN THE STUDY IN SWEDEN ARE: IPS TYPOGRAPHUS, PITYOGENES CALCOGRAPHUS, TRYPODENDRON LINEATUM, TOMICUS PINIPERDA AND TOMICUS MINOR. IN GERMANY ALSO IPS CEMBRAE AND IPS AMITINUS WILL BE STUDIED. THE RESEARCH TO BE CARRIED OUT IN SWEDEN UNDER THIS CONTRACT INCLUDES THE FOLLOWING: PREPARATION OF PHEROMONES, ENANTIOMERS, PHEROMONES, ANALOGUES, AND OTHER SUBSTANCES INCLUDING NEW SYNTHESES. CONTINUED DEVELOPMENT OF DETERRENT SUBSTANCES. STUDIES ON FORMULATIONS AND DESIGN OF DISPENSERS. LABORATORY BIOASSAYS OF SUBSTANCES WITH POTENTIAL BIOLOGICAL ACTIVITY. STUDIES ON BEHAVIOUR AND ORIENTATION OF BARK BEETLES IN THE LABORATORY AND THE FIELD. FIELD EXPERIMENTS ON ATTRACTION OF BARK BEETLES TO TRAPS BAITED WITH VARIOUS PHEROMONE MIXTURES (INCLUDING ENANTIOMERS AND ANALOGUES) AND HOST SUBSTANCES. FIELD EXPERIMENTS USING SUBSTANCES TO DETER BARK BEETLES FROM ATTACKING CONIFER STEMS AND WOOD. FIELD EXPERIMENTS INTEGRATING DETERRENCE AND ATTRACTANCE. STUDIES ON MONITORING BARK BEETLE POPULATIONS.
