Development of basic data for prediction of population dynamics and risk of attack of spotted wing drosophila (Drosophila suzukii) on fruit and grape, Subproject 3
Project
Project code: 2815HS021
Contract period: 01.01.2016
- 31.12.2018
Budget: 260,147 Euro
Purpose of research: Applied research
The main objective is to describe the development cycle of the spotted wing drosophila, Drosophila suzukii from egg to adult flies. The influence of the main meteorological factors (temperature, rel. humidity, precipitation, wind speed, etc.) as well as the influence on reproductive biology and behavior affected by the habitat plants, host plants and fruits should be investigated and described functional. These studies are intended to create a model for describing the population dynamics and the infection risk of the fruits and potential host plants. The results are both for organic and for conventional orchards and vineyards of importance On the basis of phenological models that predict the ripening of the fruits of potential host plants, the attractiveness of host fruits has to be described in terms of degree of ripeness (color, surface quality, sugar content, pH, etc.). By a dynamic population model the number of generations of D. suzukii can be calculated in combination with the duration of fruit development, starting from its attractive stage to maturation for each host plant. Per growing season a multiplication factor will be determined per host plants passage and therefore a risk factor for the infection of the next ripe crop. After the appearance of the female flies from winter habitat as start point for the first cycle of propagation in the spring the population development per region depending on appearance of host fruit will be is described until the end of the growing season.
