The principal components of climate change are increased temperature and atmospheric carbon dioxide
(CO2
) concentrations. Since climate change is believed to be more certain now, it is time for researchers to
develop management strategies to cope with increased incidence of insect pests as a result of climate change.
Of the several environmental factors temperature extremes play critical role in influencing the population of
insect pests. Our experience indicated that there is a ‘shift’ in the pest status of several key species in recent
periods, though these shifts may not be solely attributable to climate change. In the present situation, one
can expect significant changes in the growth, development and population dynamics of various insect pests.
The duration of the insect life cycle is altered under increased temperature and elevated CO2 concentrations
resulting in variable number of generations per year. Under elevated CO2
higher consumption of foliage
by leaf chewing insects with extended larval duration is observed in many studies. Published data reveals
that some pests become more serious while others may decline. Evaluating the impact of climate change
on insect pests is a very complex exercise and requires greater understanding of interactive factors. A more
critical database on biotic stresses and their relationship with drivers of climate change is required for
evolving adaptation strategies by farmers.
