Wpływ zmian klimatu na owady i roztocze związane z roślinami
Effect of climate change on insects and mites living on plants
Languages of publication
There is an essential evidence that climate is changing, both globally and locally, and the recent changes, in mean temperature in particular. are greater than the fluctuations normal over the last few centuries. Life-cycle timing in different insects depends on a wide variety of responses to both abiotic and biotic factors. Temperature directly affects development, survival range and abundance of arthropods. Species with a large geographical range are less affected, The main effect of temperature in temperate regions is to influence winter survival, Insect and mite herbivores and their intensity of herbivory increases with rising temperature at constant latitude. Photoperiod is the dominant cue for the seasonal synchrony of host plant and herbivore. A significant variation is observed in an effect of elevated CO2 on arthropods. Atmospheric CO2 concentrations have direct effects on plant primary and secondary metabolism. Insect herbivores show a number of distinct life-history strategies to exploit plants with different growth forms, which will be differentially affected by climate warming.
