Consequences of new findings of climate change with relatively warmer nights on the wheat-cereal aphid-predator interaction in computer simulations
Archives of Phytopathology and Plant Protection 31 (4), 363-367
Abstract: Computer simulations with GTLAUS 3.7 were performed to investigate the influence of different cases of increasing temperatures on the tritrophic wheat - cereal aphid - predator interaction. Two cases of a temperature increase were defined: (1) homogenous increase by adding 3°C, and (2) comparable increase with relatively wanner nights. Both cases of increasing temperatures with similar daily average values resulted in a significant reduction of aphid infestation, but this reduction was smaller in scenarios with relatively higher night temperatures. But the results indicate only relatively small differences deriving from this particularly high night temperatures.
