Abstract: In order to determine the starvation tolerances and boring behaviors of newly hatched Lasioderma serricorne larvae, their starvation tolerances at different temperatures were analyzed. In addition, their penetration rates through four packaging materials(non-woven cloth, aluminum foil, composite film, and kraft paper)were also investigated. The results showed that: 1)Temperature had significant effects on the starvation tolerances of the newly hatched larvae. The higher the ambient temperature, the worse the starvation tolerances of L. serricorne larvae would be. At 15 or 20 ℃, the newly hatched larvae could survive over 14 days without food, and all the larvae died within 24 h at 45 ℃ without food. 2) L. serricorne larvae could not enter into sound kraft paper, composite film, aluminum foil and non-woven packaging materials, however they could bore through those packaging materials with small holes(> 0.40 mm in diameter). Therefore, the packaging materials should be kept sound to prevent the harm done by L. serricorne in practice.
