Abstract
The present paper reviewed the researches of how they have affected agricultural pests in the territory of Mexico. It emphasizes that traditional climate models are not “predict” non-linear systems and are necessary to resort to the construction of scenarios for study. Some climate change models applied to Mexico used for this purpose obtained significant results. It showed that to better understand the ecology of pests and their hosts, it is necessary to further research the correlations between them and improve climate modeling and its consequences, to prioritize risks and improve the reliability of predictions and scenarios in the future.
Highlights
From a climatic point of view-agricultural, variations on the precipitation that falls over the year or several years can cause droughts, the importance of this phenomenon is evident in the cultivation of the plants and agricultural production, but that can contribute to the emergence of plant disaster, due to their effects on the development and behavior of the causative organisms of pests
Year 2011; Source: DGSV-Mexico. conditions for tested positive to the disease Candidatus Liberibacter asiaticus (HLB), as evidenced by the fact that the year 2009, presented climate anomalies associated with the phenomenon of “El Niño”, like the year 2002 that was recorded for the first time in Campeche Diaphorina citri, both years were characterized by the presence of the phenomenon of “El Niño”, so let’s say that the biological development and normal range of survival is favored, made to match cases: plague of Central American locust (Schistocerca piceifrons piceifrons Walker), Mediterranean fruit fly (Ceratitis capitata) and pink mealybug (Maconellicoccus hirsutus) and other pests [20] (Figure 2)
After observing the results obtained, we can say that most of the plagues of national priority are located in the ecological zones of the warm-humid forests and to a lesser extent in the warm-dry, in the areas of climate Aw0, related to the above, for example the vector Diaphorina citri and bacteria Candidatus Liberaribacter (HLB) which carries this psyllid has been set forth in the aforementioned sub-humid hot climates (Aw0)
Summary
From a climatic point of view-agricultural, variations on the precipitation that falls over the year or several years can cause droughts, the importance of this phenomenon is evident in the cultivation of the plants and agricultural production, but that can contribute to the emergence of plant disaster, due to their effects on the development and behavior of the causative organisms of pests. Of all the environmental factors, which exerts a greater effect on the development of insects is probably the temperature. This is mainly due to its significant impact on the biochemical processes, to be agencies poikilotherms, i.e. take the temperature of the environment [1].
