Kháng sinh được kích thích đối với động vật ăn cỏ và nội dung thông tin của cuộc tấn công đầu mùa
Tóm tắt
Các mô hình hiện tại về sự phòng thủ của cây trước động vật ăn cỏ đều giả định rằng hành vi ăn lá là có thể dự đoán được. Tổn hại hiện tại phải cung cấp thông tin về khả năng tấn công trong tương lai. Chúng tôi đã kiểm tra giả định này bằng cách đo lường mối quan hệ giữa tổn hại đầu mùa và số lượng cuộc tấn công tiếp theo của sâu ăn lá bông, Bucculatrix thurberiella, lên cây bông dại, Gossypium thurberi, tại ba địa điểm ở sa mạc Sonoran. Tổn hại đầu mùa là một chỉ số tốt cho số lượng mỏ mới được tạo ra trong suốt mùa ở cây ở Florida Canyon. Kết quả này既不支持也不反对诱导抵抗，也不是诱导抵抗的结果。这是因为人们发现诱导的抵抗影响矿工的生存，但早期的破坏并不影响新矿的启动。在另外两个地点，早期损伤与未来攻击无关。这种可预测性差异可能与植物的诱导能力有关，因为佛罗里达峡谷是唯一在先前研究中提供诱导抵抗证据的位置。我们没有发现基于早季损伤的信息的有用性随季节的进展而降低的证据。在对植物所有枝条的攻击评估中，预测对一个检定植物的后期损害比仅评估检定植物更有效。由G. thurberiella造成的矿洞数量比由许多不同食草动物造成的咬合和刮擦更能预测随后的G. thurberiella 攻击。然而，一般的啃咬损害比更具体的采矿损害更能指示对G. thurberiella的诱导水平。尽管采矿损害是未来攻击的更好预测指标，植物可能对啃咬损害的反应更强烈。
