Solution(By Examveda Team)

The pest which attacks both in the field and storage of pulses is Pulse beetle.
The most important insects damaging pulses in field and storage are referred to as bruchids or pulse beetles.
Adult pulse beetles, being very weak and having a short life, cannot move in grain mass and are restricted to top 15 cm layer. Even the adults emerging out of the infected material cannot move in the intergranular space and could die before mating. Movement of adult pulse beetle can be prevented by placing a 7 - 10 cm layer of dry sand at the top of grain mass.
