...Similarly, while a combination of heat and drought may reduce the population of cereal aphids in southern Britain, if aphid predators are affected to an even greater degree, then the predicted reduction in aphids may be negated (Newman, 2005)....

...Overall, the results of this and subsequent work demonstrated that climate change would benefit the cereal production of developed countries more than the developing countries, even if cropping practices evolved to allow more than one rainfed crop per year (Fischer et al., 2002, 2005)....

...Changing climate has already affected the geographical distribution of some crop pests and pathogens [e.g. Puccinia graminis f.sp. tritici (stem rust) and Dickea dianthicola; Woods et al., 2005; Admassu et al., 2009; courtesy of DELl Cooke, SCRI....

...Another example of this type of model is the increased range of stem rust, and, in particular, the race known as Ug99 which has virulence towards the Sr31 resistance gene (1B/1R translocation) which is used extensively in wheat varieties across the world (Admassu et al., 2009)....
