捕食者可以通过杀死食草动物间接减少食草动物。此外,捕食风险也会影响食草动物的摄食率和摄食位置。食草动物应该避开目前被捕食者占据的植物。因此,较少的食草动物,预计对植物轴承新鲜的捕食线索。我们研究了是否木蟋蟀,Nemobius sylvestrisBosc(直翅目:蟋蟀科),避免植物轴承的化学线索苗圃网蜘蛛,Pisaura mirabilisClerck(蜘蛛目:Pisauridae),或红木蚂蚁,红蚂蚁。(膜翅目:蚁科)。我们进行了一系列的行为实验,在这些实验中,蟋蟀可以选择一株有蜘蛛或蚂蚁线索的植物与一株对照植物,一株有蜘蛛线索的植物与一株有蚂蚁线索的植物,或者两株对照植物。对于所有植物,我们量化了叶片损伤以及蟋蟀的位置和重量变化。蟋蟀避开有蜘蛛信号的植物。相比之下,蚂蚁的线索并没有显着阻止蟋蟀。植物间的取食格局反映了蟋蟀对植物的选择。然而,净草食动物不受捕食者线索的存在。因此,我们的研究结果表明,蜘蛛线索影响觅食的位置,而不是草食动物的总量。
Predators can indirectly reduce herbivory by killing herbivores. In addition, predation risk can influence the feeding rate and feeding location of herbivores. Herbivores are expected to avoid plants currently occupied by a predator. Consequently, less herbivory is expected on plants bearing fresh predator cues. We examined whether wood crickets,Nemobius sylvestrisBosc (Orthoptera: Gryllidae), avoided plants bearing the chemical cues of nursery web spiders,Pisaura mirabilisClerck (Araneae: Pisauridae), or red wood ants,Formica rufaL. (Hymenoptera: Formicidae). We conducted a series of behavioural experiments, in which crickets had the choice between a plant with spider or ant cues vs. a control plant, a plant with spider cues vs. a plant with ant cues, or two control plants. For all plants, we quantified leaf damage and the position and weight change in the crickets. Crickets avoided plants with spider cues. In contrast, ant cues did not significantly deter crickets. The herbivory pattern among the plants reflected the plant choice of the crickets. However, net herbivory was not affected by the presence of predator cues. Thus, our results suggest that spider cues affect feeding location rather than the total amount of herbivory.
