Abstract
The European spruce bark beetle is the most important damaging agent for Norway spruce. In the last decades, large abiotic disturbances and consequently bark beetles outbreaks in forests have been taken place. The ongoing climate change with more weather extremes, like drought and ice storms makes it muc more likely that this will happen more often in the future. In order to act against such an large scale outbreak, the source should be found as soon as possible. In Slovenia a monitoring system with pheromone traps exist which monitores the number of bark beetles and can see whether there will be an outbreak of bark beetles. However at this moment the monitoring system is inefficient and very costly. New types of traps, pheromones and better guidance in number of traps and location of traps would make the monitoring system more efficient and cost effective. This project will be divided into five work packages: 1) project management, 2) Modelling and computer application for optimizing the number and the location of the traps, 3) testing different pheromones and trap types for monitoring the bark beetle abundance, 4) dissimination of the project results and 5) proposals for legislations regarding bark beetles. From the proposed project the following results will be provided: To define criteria, deadlines and procedures for determinig the optimal number of control pheromone traps and their setting locations, taking into account local differences in geographical, climatic and cological characteristics of individual areas, To define criteria and procedures for determining the optimal number and locations of control settings; To compare the effectiveness of the different pheromones types (e.g. Pheroprax, ECOLURE, Typosan) on the catch of the European spruce bark beetle and of side catch, focusing especially on predators of the European spruce bark beetle in the areas affected by natural disasters, to compare the effectiveness of different trap types for the European spruce bark beetle with the same attractant (e.g. barrier trap, cross vein trap) and the side catch with focusing especially on predators of the European spruce bark beetle in the areas affected by natural disasters, to compare the efficiency of single, double and triple Theysohn trap on the caught number of the European spruce bark beetle, to create publicly available web applications for planning the number and setting locations of control traps and control settings for individual regulatory units of the Slovenian Forest Service (ZGS), to publish a publication that informs forest owners about the danger and damage caused by the European spruce bark beetle and to raise awareness about the meaning of traps setting, to organize workshops for forest owners in order to raise awareness about the danger and damage caused by the European spruce bark beetle and to raise awareness about the meaning of traps setting; and to review the forestry regulations and assess the adequacy of forest protection regulations (monitoring the occurrence of the European spruce bark beetlesin forests and warehouses, detection of their source, repressive measures and deadlines for implementation). From the proposed project the following results will be provided: Criteria, deadlines and procedures for determining the optimum number and the location of pheromone traps (elaborate). Criteria, deadlines, and procedures for determining the optimum number and the setting locations of the control settings. Model for determining the optimal number and the location of pheromone traps. Model for determining the optimum number and the location of control settings.

Significance for science
At the moment, the monitoring system for spruce bark beetles already exists for more the 20 years, but it has not adapted to the contemporary technology and there are many possibilities to make the system more efficient in order to react to bark beetle outbreaks in the future. This project would be therefore in different ways important for science and forestry in particular. An optimized monitoring system for catching spruce bark beetles in control pheromone traps (DS2) will provide more economical maintenance of the control pheromone trap system to monitor the abundance of spruce bark beetles, both in terms of time consumption and the consumption of financial and other assets. An optimized monitoring system for spruce populations with control pheromone traps and control settings (DS2) increases the reliability of forecasting the development of populations and the multiplication of spruce bark beetles. During the project the efficiency of different traps will be tested. The aim is to see which traps are best to catch european spruce bark beetle (Ips typographus) and possible natural enemies like predators and parasitoids. The outcome would give the trapping method which would give a good insight to the status of the population of the european spruce bark beetle. Beside that this project would also show the method which are least affecting the natural enemies of the european spruce bark beetle. In the last years several type of pheromones were developed for the European spruce bark beetle. At the moment it is not known which is the most cost effective. Therefore a comparison in catch between the pheromone types should be made and the efficiency of the pheromones should be tested. We would show which pheromone is best for the monitor bark beetles and in the same time does not affect the population pressure by natural enemies like predators and parasitoid.
Significance for the country
Norway spruce (Picea abies) is one of the most abundant species in Slovenia. This species is economically very important, it is basis of the majority of the wood processing industry in Europe. European spruce bark beetles attacks yearly huge quantities of Norway spruce and are therefore one of the most important pest of this tree species. Therefore good working pest management system is needed to reduce the destructive attacks of the bark beetles. One of the most crucial parts of pest management is the early detection of the bark beetle outbreaks. When a bark beetle outbreak is detected the slovenia Forest Service can fell the attacked tree and avoid that bark beetles will attack other healthy trees. This project is aiming to optimise the monitoring system for bark beetles and therefore reduce the damage by bark beetles. Installation and maintenance (replacement of pheromones, trap cleaning) represent a great cost. The methods used to monitor the abundance and development of spruce populations are not optimal. An optimized monitoring system for catching spruce bark beetles in pheromone traps (DS2) will reduce the costs of maintaining the control pheromone trap system in order to monitor the abundance of spruce bark, both in terms of time consumption and the consumption of financial and other assets. The proposed project will upgrade the electronic forest protection system in Slovenia, which is part of the Public Forestry Service, which is carried out by the Slovenia Forest Service and the Slovenian Forestry Institute. This will upgrade the social infrastructure for state administration. The Electronic Forest Protection System will be richer for two online interactive applications: (1) an online application for planning the number and locations of control traps; (2) web application for planning the number and locations of control settings. The reporting, prognostic-diagnostic service for forests will become richer for several prognostic models: (1) a model for determining the optimal number and location of the pheromone traps; (2) a model for determining the optimal number and locations for setting up control assignments.
