We examined behavioral alterations in the brown cockroach, Periplaneta brunnea, infected with the acanthocephalan, Moniliformis moniliformis. The responses of infected and uninfected P. brunnea to light, substrate choice, and activity were compared. Infected brown cockroaches spent more time on white horizontal substrates under red and white light. Infected brown cockroaches also had a shorter freeze time than uninfected cockroaches after being presented with a light source. There was no difference in photophilia or activity of infected and uninfected brown cockroaches. These behavioral alterations in brown cockroaches were compared to those in Periplaneta americana, the American cockroach, infected with the same parasite. American and brown cockroaches differed in some responses to substrate, phototaxis, and activity.
我们研究了感染棘头虫——念珠棘头虫的棕色蟑螂（褐斑大蠊）的行为变化。比较了感染和未感染褐斑大蠊对光照、底物选择和活动的反应。感染的棕色蟑螂在红光和白光下在白色水平底物上花费的时间更多。在有光源出现后，感染的棕色蟑螂的静止时间也比未感染的蟑螂短。感染和未感染的棕色蟑螂在趋光性或活动方面没有差异。将棕色蟑螂的这些行为变化与感染相同寄生虫的美洲蟑螂（美国蟑螂）的行为变化进行了比较。美洲蟑螂和棕色蟑螂在对底物、趋光性和活动的一些反应上存在差异。
