杂食性是指动物从两个或两个以上的营养级捕食生物的一种食性。杂食性物种在捕食者-猎物相互作用、食物网动态和生态系统功能中起着重要作用。虽然蟋蟀物种被认为是杂食动物，但对其食性的定量调查尚未进行。因此，我们比较了在肉食动物和草食动物的饮食中饲养的带腿地蟋蟀Dianemobius nigrofasciatus（Matsumura）（直翅目：Trigonidididae）的发育时间，体型和死亡率。此外，为了检查蟋蟀是否可以通过食物选择来平衡它们的营养状况，我们设置了两个额外的饮食处理，其中包括同时或轮流提供的食肉动物和食草动物的饮食。肉食性饲料处理的死亡率高于其他饲料处理。这一结果表明，黑线姬鼠是一种“草食动物”，也从植物材料以外的资源获得营养。虽然发育时间没有显着差异的饮食治疗，蟋蟀的身体大小，同时提供两种饮食是显着大于蟋蟀提供的饮食，无论是食肉动物或食草动物。这些结果表明，适量的肉食性饲养有利于蟋蟀的生长发育，并表明蟋蟀能自行平衡营养。
Omnivory is a feeding habit in which animals prey on organisms from two or more trophic levels. Omnivorous species play important roles in predator–prey interactions, food web dynamics, and ecosystem functions. Although cricket species have been considered omnivores, quantified investigations of their feeding habits have not been carried out. Therefore, we compared the developmental time, body size and mortality rate of the band‐legged ground cricket,Dianemobius nigrofasciatus(Matsumura) (Orthoptera: Trigonidiidae) reared on diets meant for carnivores and herbivores. Furthermore, to examine whether the crickets can balance their nutritional conditions through their food choices, we set up two additional diet treatments, which comprised diets for carnivores and herbivores provided simultaneously or by rotation. The mortality rate of the carnivore diet treatment was higher than that of the other diet treatments. This result suggests thatD. nigrofasciatusis a “herbivore” that also obtains nutrients from resources other than plant materials. Although developmental time did not significantly differ among the dietary treatments, the body size of the crickets that were provided both diets simultaneously was significantly larger than that of the crickets provided with only the diets for either carnivores or herbivores. These results suggest that an appropriate amount of carnivorous feeding is advantageous for the development of the cricket, and indicates that crickets can balance nutrition on their own.
