Results
The total number of generations that can be completed by C. serratus in a year in India was
visualized using ArcGIS for current (baseline worldclim climate data for the year 2000) and
future projections based on the ensemble of eight GCMs (year 2050) (Fig. 1). The generation
indices are directly correlated with the abundance and potential infestation of C. serratus under
stored conditions. Ensemble model has predicted 3-3.46 generations of C. serratus in a year in
a major part of India. The Himalayan region area and its ranges from north to north-eastern
regions are predicted to have 1-2.14 generations in a year under current climatic conditions.
Under future climate change scenarios (2050), maximum regions of India, except Northern
Himalayan and top of north-eastern states, are predicted with more than three generations of
C. serratus in a year. In the present study, the model outputs represent only the potential
population growth parameters for C. serratus in a given agro-ecological region. Thus, it needs
to be cautiously interpreted while predicting stored dynamics and abundance of C. serratus
population, where abiotic and biotic factors other than temperature do come to play the role in
regulating pest population dynamics. The present results indicate that temperature is vital in
influencing the growth and life table parameters of C. serratus and this pest incidence is likely
to be higher in the future climate change periods in India.
