| Abstract | ||||
| Climate change and global warming are of great concern to agriculture worldwide and are among the most discussed issues in today’s society. Climate parameters such as increased temperatures, rising atmospheric CO2 levels, and changing precipitation patterns have significant impacts on agricultural production and on agricultural insect pests. Changes in climate can affect insect pests in several ways. As a result, there is a serious risk of crop economic losses, as well as a challenge to human food security. As a major driver of pest population dynamics, climate change will require adaptive management strategies to deal with the changing status of pests. Several priorities can be identified for future research on the effects of climatic changes on agricultural insect pests. The popoulation abundance of the two-spotted spider mite, Tetranychus urticae infesting Phaseolus vulgaris L plants in upper Egypt was studied during spring plantations of 2015 and 2016 season. The obtained results showed that, the spider mite population fluctuated in its density during the whole season of both studied years with a peak number occurrence the end of season (May 30), when plant age was 90 day-olds when temperature and relative humidity were in moderate levels. Also, the current study showed that, Phaseolus vulgaris L plants severely affected by the pest in addition to the few numbers of predators were observed during this season. The temperature and relative humidity, in addition to the plant age probably play an important role in the infestation other than the biotic factors (predators). Accordingly, further studies are required to set up and confirm the main factors affecting the population of this pest. This study is useful for determining the timing of the control program for the two-spotted spider mite, Tetranychus urticae infesting Phaseolus vulgaris L plants during spring plantations. | ||||
