General Information

:

The basic characteristics of the stored product insects, viz., affinity towards air, tendency to move towards aerated region, wander in the grain and active during dusk and dawn have been exploited in the development of the trap. The stored grain insects, like red flour beetle, saw toothed beetle, rice weevil, paddy moth, turmeric beetle, drug  beetle, pulse beetle, groundnut bruchid, dermestid beetles, flat grain beetles, etc  with the behaviour of wandering in the bulk grain, reach the insect trap. These insects enter the trap through the perforations and reach the stem of the trap. In the stem, as the insects cannot move upward and escape, they move towards the bottom and reach the pit fall placed at the bottom.
