当食草螨在其群体中遇到捕食螨时，它们从殖民地分散到另一片叶子上以逃避捕食者。然而，替代补丁可能已经被其他食草动物竞争对手使用。我们研究了草食螨是否改变其传播的替代补丁，无论是同种，或豇豆蚜虫，或常见的地老虎，当他们认为挥发物从补丁侵扰的竞争对手。植食性螨减少了与普通地老虎的交替叶斑的扩散，从而在叶斑中诱导对自身的抗性。我们证实，减少扩散将是一个响应叶挥发物诱导的常见地老虎。
When herbivorous mites encounter with predatory mites in their colony, they disperse from the colony to an alternative leaf patch to escape from the predators. However, the alternative patch may have been used by other herbivore competitors. We studied whether the herbivorous mites change their dispersal to the alternative patch with either conspecifics, or cowpea aphids, or common cutworms when they perceived volatiles from the patch infested by the competitors. The herbivorous mites reduced the dispersal to the alternative leaf patch with common cutworms that induced resistance to themselves in the leaf patch. We confirmed that the reduced dispersal would be a response to leaf volatiles induced by common cutworms.
