Abstract: The data acquisition film medium is a gridwork of lines applied to read the distribution and population of insects captured on sticky material on a substrate. The data acquisition gridwork of lines may be applied to the substrate under the sticky material or may be applied to a separate transparent data acquisition film which is applied over the sticky material and insects captured thereon after use of the substrate with its sticky material. The separate transparent data acquisition medium may be in panels to cover the sticky material on capture glueboards, on either one side or both sides of the glueboard, may be in bag form for receiving the glueboards, may be on a roll with tear-off edge, may be wrapped around a single-sided or double-sided glueboard, or may be a long length of film to apply onto a long length of substrate carrying sticky material in an advancing manner in an insect light trap.
