Relațiile dintre culturile agricole și organismele dăunătoare în condițiile schimbărilor climatice

Voloșciuc, Leonid
The analysis of the evolution of the degree of development of disease pathogens and harmful arthropods was carried out, which demonstrates that the losses of agricultural production caused by harmful organisms (25-30%) have a permanent increasing trend. Experimentally approved scenarios and models (CSIRO Mk2, HadCM2 and ECHAM4) regarding the consequences of climate change allow predicting the penetration and selection of varieties with an increased degree of damage, widening the area of spread, increasing the virulence and aggressiveness of pathogen species, increasing the number of generations, which will cause increased harvest losses of agricultural crops. In recent decades, many papers have been published on the analysis of the impact of global climate change factors on the development and harmfulness of pests. The changes are due both to the direct influence of climatic factors on the harmful organisms, and to indirect effects through changes in the metabolism of the host plants. In order to avoid or re-duce the negative impact of harmful organisms in the conditions of climate change, it is proposed to develop and implement alternative means of combating of pests with the wide use of biological methods of plant protection.
