Abstract:
From past three years (i.e. 2018) lepidopteran pest Fall armyworm Spodoptra frugiperda (J.E. Smith) became severe on maize crop in India which was earlier reported in Africa for the first time on late 2016. The distribution and abundance of Fall Armyworm are largely influenced by the relationship between development rate which is dependent and temperature which is independent. A change in temperature influences the developmental rate of insects as development of insects occurs within a specific temperature. Temperature also influences the duration of life cycle and ultimately the survival rate and mortality. The experiment was conducted on “Effect of temperature on the development of Fall Armyworm- Spodoptera frugiperda (J.E. Smith) under laboratory condition” Agricultural Entomology Section, College of Agriculture, Pune, during the year of 2020-21. The influence of temperature was studied at the temperature range of 18, 22, 26, 30, 32 ⁰C ±2 ⁰C and 65 ± 10% relative humidity with a 14:10 h (L: D) in BOD incubator.
