Application of phenology models for Climate Services Organic Eprints
Felber, Raphael; Stöckli, Sibylle; Calanca, Pierluigi.
Global warming is expected to accelerate the development of plants and insects leading to earlier occurrence of phenological stages than under today’s climate. This can alter the exposure of plants to extreme climate events and further change the synchrony between host plants and pest insects. Assessing the implications of earlier development for the exposure to risks is necessary to inform adaptation. In this contribution we present an analysis of potential impacts of climate change on (i) the risk of early frost in apple orchards and damages to apple fruits due to critically high temperatures, (ii) the time of apple picking, and (iii) the potential of damages caused by the codling moth (Cydia pomonella L.), for three different apple cultivars in...

Assessing climate change impacts on fruit plant and pest phenology and their synchrony: the case of apple and codling moth Organic Eprints
Felber, Raphael; Stöckli, Sibylle; Calanca, Pierluigi.
Temperature is a main climatic driver of plant phenology and the dominant abiotic factor directly affecting insect pests. Global warming is therefore expected to accelerate the development of plants and insects alike. In the case of multivoltine pest species, it was shown that higher temperatures lead to the appearance of additional generations toward the end of the warm season (Stöckli et al., 2012), which also has implications for pest management. The same effect was shown for the timing of flowering termination of apple trees (Stöckli and Samietz, 2015), the time when a pest can attack a fruit. In practice, however, much would depend on whether plant and pest phenology remain synchronized or not. Focusing on Switzerland, in this contribution we...
