Model based risk assessment of oak processionary moth in climate change. Subproject 3: Investigation of the influence of natural microbial antagonists of the oak processionary moth under different conditions in different regions of Germany (ModEPSKlim)
Project
Project code: 28WC409003, JKI-BI-08-1223
Contract period: 01.03.2016
- 30.09.2019
Budget: 39,664 Euro
Purpose of research: Applied research
In close cooperation with the subproject 2A, dealing with natural parasites, parasitoids and predators of the oak processionary moth (OPS), microbial antagonists including viruses of OPS will be examined in the JKI Institute for Biological Control. It is known that naturally occurring insect-specific pathogens contribute steadily for decimating insect calamities. Therefore, their impact on population densities of OPS under different climatic conditions in selected regions of Germany will be studied in this project. Various stages of development of the OPS will be considered. The data of infection rates and spectra of parasites and parasitoids (TP2A NW-FVA) and pathogens (TP2B, JKI) will be determined for this purpose, and at the same time, the influence of these antagonists of the OPS on its population dynamics will be examined. Furthermore, the virulence of the pathogens will be tested against various caterpillars’ developmental stages of OPS. In this study, the impact of natural antagonists on the population density of the oak processionary moth (EPS) under different climatic conditions will be conducted in selected regions of the federal states of Baden-Wuerttemberg, Bavaria, Lower Saxony, Saxony-Anhalt, Brandenburg and Schleswig-Holstein in collaboration with the subproject 2A. Therefore, approx. 100 larvae per selected area of investigation will be examined diagnostically per year. In six federal states, and 1-2 study plots each, this will be a total of 600-700 samples. In order to evaluate possible new biological control measures with insect pathogens, it is planned to evaluate the virulence of pathogens that will be diagnosed during the study, in laboratory and field trials against different developmental stages of EPS.
Microbial antagonists including viruses of the oak processionary moth (OPS) are examined in the JKI Institute for Biological Control. It is known that naturally occurring insect-specific pathogens contribute to the control of insect calamities. Therefore, their impact on population densities of OPS under different climatic conditions in selected regions of Germany will be studied in this project. Various stages of development of the OPS are considered. The final goal of the project is the development of an early warning system for effective OPS control.
