Anoplophora glabripennis is a serious pest of maple and other hardwoods. The insect has been introduced into the United States via wood packing materials, and programs are underway to eradicate populations in the New York City and Chicago areas. Studies on activity patterns of adult A. glabripennis were conducted on Populus in the field in Ningxia A.R., P.R. China, to provide basic information that could be useful in the design and development of survey and control measures. Groups of adult beetles were observed several times daily, and data on various aspects of the beetle’s behavior were noted (e.g., sex of beetle, type of activity, substrate, height off of ground). In some cases, beetles were marked, allowing positions of individual insects to be tracked from observation to observation. At all times of day, the majority of observed beetles (70 to >90%) were resting. In general, percentages of beetles on boles and large stems were low (20% or less) in the early morning, but increased to around 40% during the rest of the day. Patterns of activity during the course of the day showed some other apparent patterns, but these appeared to be related more to environmental conditions than to diurnal behavioral rhythms. Marked beetles left the study area slowly; approximately 50% of marked beetles were observed the second day after release, but few marked beetles were found after six days.
