Computerized moving-image analysis was used to determine movement behavior of adult German cockroaches among food, water, and harborage resource sites. Adults at different stages in the female reproductive cycle (nonmated females, mated nongravid females, and gravid females) and males were examined continually for 5 d under a photoperiod of 12:12 (L:D) h. Corresponding food and water consumption rates for these adult classes were also determined. Differences were evident among the female reproductive classes and males. Mated nongravid females were the most active overall, and consumed the most resources. Nonmated females were second to the mated nongravid females in consumption and were less active. Gravid females were the most inactive, spending the greatest time in the harborage and consuming the fewest resources. Males were second to females in the mated nongravid class regarding activity, but consumed significantly fewer resources than females in both the mated nongravid and nongravid females. Implications of these findings relating to the biology of these adult classes are discussed.
利用计算机化的运动图像分析来确定成年德国小蠊在食物、水和栖息资源位点之间的运动行为。在12:12（光照：黑暗）小时的光周期下，对处于雌性生殖周期不同阶段的成虫（未交配的雌性、已交配未受孕的雌性和受孕的雌性）以及雄性成虫持续观察5天。还测定了这些成虫类别的相应食物和水消耗率。雌性生殖类别和雄性之间存在明显差异。已交配未受孕的雌性总体上最活跃，消耗的资源最多。未交配的雌性在消耗量上仅次于已交配未受孕的雌性，且活跃度较低。受孕的雌性最不活跃，在栖息处花费的时间最长，消耗的资源最少。在活跃度方面，雄性仅次于已交配未受孕类别的雌性，但在已交配未受孕的雌性和未交配的雌性中，雄性消耗的资源明显少于雌性。讨论了这些发现与这些成虫类别的生物学特性相关的意义。
