Project
Project code: 22012918
Contract period: 01.05.2019

Budget: 499,778 Euro
Purpose of research: Applied research
VerbIps at a Glance • Verbenone is an important pheromone of spruce bark beetle (Ips typographus) with an anti-aggregating effect. • SPLAT®Verb is an innovative dispenser-pheromone-formulation for the regulated use of the otherwise highly volatile verbenone in the field. • The project aims to develop of a pheromone-based method for an environmentally friendly integrated bark-beetle management in outbreak situations. • The basic suitability of SPLAT®Verb against bark beetle aggregation and -infestation, the range, duration and required quantities are checked, and the application for area protection is examined and the application options are to be investigated. Therefore, the project deals with the following questions: 1. What is the effectiveness of SPLAT®Verb in forests? The effectiveness of SPLAT®Verb will be tested in various silvicultural situations, the quantities of SPLAT®Verb to be applied to obtain a sufficient effectiveness are to be determined. 2. At what distance and for how long does SPLAT®Verb show sufficient effect? It should be tested whether the effect lasts sufficiently long over a growing season, or whether SPLAT®Verb has to be applied several times in one year. 3. Which release of verbenone is necessary to trigger behavioural reactions of beetles of different of sex or age? he project will determine (i) which concentrations of the verbenone are necessary to achieve an anti-aggregating effect and (ii) whether different thresholds exist for beetles of different age and for the two sexes. 4. Are there interactions between host-born substances and verbenone? Systematic measurements of the atmosphere near the trapping trees in combination with the evaluation of brood pattern lead to correlations between verbenone, breeding success and host-born substances. 5. Can SPLAT®Verb achieve a wide-area effect on approx. one hectare of a spruce forest? It is important to evaluate the use of SPLAT®Verb for the protection of whole stands.
