The behavior of the cockroach Diploptera punctata parasitized with the acanthocephalan Moniliformis moniliformis was examined for parasite-induced alterations. No significant difference in behavior was found between parasitized and unparasitized animals in the following behavioral tests: (1) choice of white/black, horizontal/vertical substrate under light and dark conditions; (2) temporal and directional response to a bright light source; (3) choice between light and dark (photophilia); and (4) activity (time spent moving, distance, and velocity). A comparison of uninfected animals under 2 light conditions showed that light affected the activity of uninfected animals and their response to substrate. Diploptera punctata is the first nondomestic cockroach to be examined for behavioral responses to Moniliformis infection. This is the first report of an arthropod in which acanthocephalan infection has failed to alter behavior under at least some common test conditions.
研究了感染棘头虫念珠棘头虫的斑点折翅蠊的行为，以观察寄生虫引起的变化。在以下行为测试中，未发现受感染和未受感染动物在行为上有显著差异：（1）在明暗条件下对白色/黑色、水平/垂直基质的选择；（2）对明亮光源的时间和方向反应；（3）在光和暗之间的选择（趋光性）；（4）活动（移动时间、距离和速度）。对两种光照条件下未感染动物的比较表明，光照会影响未感染动物的活动及其对基质的反应。斑点折翅蠊是第一种被研究对念珠棘头虫感染行为反应的非家养蟑螂。这是关于节肢动物的第一份报告，其中棘头虫感染在至少一些常见测试条件下未能改变行为。
