Abstract

Computed tomography was used to study the burrowing activity of larvae of Sitotroga cerealella Olivier, 1789 (Lepidoptera: Gelechiidae) in damaged maize grain. The randomly selected cobs were shelled, and the damaged maize grains were measured. The volumes and locations of cavities formed by larvae were mapped by means of a new computer-based three-dimensional imaging method. The use of new technologies have greatly improved and facilitated the detailed investigation of injured grain. The results provided additional data for biological information to covertly developing S. Cerealella. Significant volume destructions were observed only in the highly perforated grains (P = 0.032). The embryos of the infested grain were destroyed independent of the number of larvae. The emerged holes and the larval cavities were found to be linked by larval passages, which have been prepared directly before the pupation.
