Ocimum basilicum belongs to family Lameaceae and is a summer, herbaceous annual plant, of tropical and warm areas, such as India, Africa and Southern Asia. The minimum temperature for the growth of sweet basil has been determined to be 10.9oC and maximum temperature is 29.1oC. Climate change is affecting medicinal and aromatic plants around the world and could ultimately lead to losses of some key species. Global warming enhance the CO2 assimilation in plant and increase the plant temperature and plant need more water and in lack of more water, the plant wilt up and get dried. Heavy shading strongly reduces total volatile oil content in fresh leaves. Monanthia globulifera, a phytophagous bug, damages this plant. Infestation of Monanthia globulifera on Ocimum basilicum lasts from April to October. Climate change increase the population of Monanthia globulifera and this bug will affect the plant for long time, which will result ultimately death of the plant.
