Fig. 6 Change in the generation index (GI) of P. solenopsis in India at current (1950–2000) (a) and future (SRES A1B
scenario 2050) (b) climatic conditions simulated using interpolated minimum and maximum temperature data from
worldclim database. The index represents mean number of generations; a P solenopsis population can produce within a
year under current (a) and future (b) climatic conditions
Fig. 5 Establishment and distribution of P. solenopsis in India at current (1950–2000) (a) and future (SRES A1B
scenario 2050) (b) climatic conditions simulated using interpolated minimum and maximum temperature data from
worldclim database. P. solenopsis is rarely established in the geographical regions on a map where the index value is
lower than 0.8
