Interpretive Summary: not required

Technical Abstract: Three corn fields were sampled continuously for 6- or 8-wks to determine the invasion patterns of the maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), infestation. The weekly samplings started when the kernel moisture level was about 30%. The weevil infestation levels varied significantly among the three fields. The key spatial pattern was shown by the edge effect of the fields on weevil distribution, while the key temporal pattern was demonstrated by the gradual dispersal of the weevils throughout the 6- or 8-wk sampling period. The ramifications of the findings for other research and farm practice were also discussed.
