S. litura is a polyphagous pest on agri-horticultural systems and reported to feed on more than 120 species
of host plants. The lower and upper threshold temperatures of 10.5° and 37°C and thermal degree unit requirement
for egg-egg development for S. litura (551.20 per generation) obtained from literature was used for modeling.
Based on thermal requirements, risk maps indicating the potential number of generations of S. litura per year
was calculated for different parts of India for current and 2030 (for A2 scenario obtained from CliMond) using
CLIMEX. Subsequently, the maps were incorporated into DIVA-GIS software for suitable contrast colour
codes corresponding to number of generations.
In the current climatic conditions, most of the northern and north eastern states are expected to have less
than 9 generations/yr (Fig 1). Central India is projected to have 9-10 generations/yr and parts of Tamil Nadu,
Andhra Pradesh and Kerala are predicted to have 11-12 generations/yr. Under climate change scenario (2030)
an overall increase of 1-2 generations is expected. More than 12 generations are expected in parts of Andhra
Pradesh and Tamil Nadu. Though in these regions extreme temperature will hinder its development, the pest is
still expected to complete 12 generations during favourable months.
