The present invention relates to a method for monitoring crops during storage comprising storing the crops at different locations being geographically remote from each other, at each geographical location (1), covering the crops with at least one cover (6-1, 6-2, 6-3) which has a protective activity against harmful organisms, at each geographical location, arranging at least one trap (8, 9) for the harmful organisms at least inside the cover, said trap is adapted to capture the harmful organisms such that the caught harmful organisms can be counted, at each geographical location, transferring a first set of characteristics of the trap to a local computer (10) device of said geographical location, said first set of characteristics include for each trap at least the current number of harmful organisms caught by said trap, wherein at least one of the characteristics of the first set of characteristics is transferred by an optical, a wireless and/or an electronic interface from the trap to the local computer device, transferring a second set characteristics of the trap from the local computer device to a central computer device via a network, said transferred second set of characteristics include for each trap at least the number of harmful organisms caught by the respective trap and a location characteristic of the trap, and at the central computer device, analyzing the characteristics of the trap that have been transferred from the local computer devices. Furthermore, the invention relates to a system for carrying out this method and the use of this system for monitoring tobacco, dried fruit, nuts and/or cocoa.La présente invention porte sur un procédé pour surveiller des cultures pendant le stockage, lequel procédé met en œuvre le stockage des cultures en différents emplacements qui sont géographiquement distincts les uns des autres, et, en chaque emplacement géographique (1), le recouvrement des cultures avec au moins une couverture (6-1, 6-2, 6-3) qui a une activit
