Abstract:
The experiment was conducted in the central laboratory of Sher-e-Bangla Agricultural
University (SAU), Dhaka – 1207, Bangladesh during the period from July 2017 to June
2018 to study the succession of insect pests in stored groundnut and their control. Six
treatments such as T

= Red chili powder @ 1.0
= Turmeric powder @ 1.0
= Coriander seed powder @ 1.0 g/200 g seed of groundnut and T
Control (untreated) were used in this experiment. Treated and untreated containers were
kept open in laboratory for natural infestation of insect pests. Two insect pests namely
dried fruit beetle (Carpophilus hemipterous) and red flour beetle (Tribolium castaneum)
were found to attack in stored groundnut seeds. Dried fruit beetle population was higher
upto 315 days after storage. Sevin 85 SP provided the best protection against these pests
in storage compared plant materials. Among the four plant materials, neem leaf powder
gave better results for protection of groundnut seed in storage compared to other three
plant materials.
