Device and system for monitoring the risk of pest infestation in a grain storage environment

An insect trap device in a cereal storage environment including a slender hollow body having:

• a medial portion including a plurality of openings opening into an internal volume of said medial portion defining a capture zone of said insects, and further including a guide held at a central position within the medial portion;
• a lower portion wherein the internal volume defines a trapping zone of said insects, said medial portion and said lower portion being connected by a non-return opening system,
• the insect trap device comprising an on-board electronic module comprising:
• a) at least one detection sensor disposed in the trapping zone, configured to capture at least one item of information representative of an infestation risk in said trapping zone and generate at least one risk data item containing said at least one item of information;
• b) wireless transmission means configured to transmit said at least one risk data item to an offset electronic entity;
• and
• c) at least one cable that runs through the guide, providing an electronic link between the at least one detection sensor and the other components of the on-board electronic module.
