The immigration of Rhyzopertha dominica (F.) into wheat stored on farm suggests that movement of this pest from outside sources, such as other farm bins on site, other farm locations, or wooded areas, may be important. However, the long range dispersal behavior of this pest is unknown. A mark-release-recapture study was done at the Konza Prairie, Kansas, in 2004 to determine flight distance of R. dominica in the field. Marked beetles reared in the laboratory were released in the center of a grid of 46 Lindgren traps placed in concentric circles out to 1 km, with traps placed in the north, northeast, east, southeast, south, southwest, west, and northwest directions. Beetles were recaptured up to a distance of 432±283 m, with minimum and maximum distances of 50 m and 1000 m within 3 days. Additional traps placed outside the grid indicated that beetles could be captured as far as 3.6 km. A 3.5% recapture rate of about 10,000 released beetles was achieved. Wind speed and solar radiation were critical environmental factors affecting flight activity, as shown by stepwise regression analysis. This study shows the potential dispersal distance of lesser grain borer needs to be considered in management of this pest.
