Adoxophyes honmaiYasuda（鳞翅目：Tortricidae）是日本茶树的严重害虫。幼虫为害广泛分布于整个茶园，但其产卵和取食方式尚不清楚。因此，本研究的目的是确定 A 叶龄的产卵偏好。 honmaias 与后代的表现有关。嫩叶和老叶的二选实验表明：A.本麦雌性成虫更喜欢在靠近老叶的区域而不是嫩叶处产卵。因此，老茶叶中的挥发物似乎充当引诱剂并刺激产卵。相比之下，超过70%的新生幼虫在实验开始24小时后就以幼叶为食，并且持续以幼叶为食的幼虫的发育高于以老叶为食的幼虫。孵化后，新生儿可能会移动到幼叶处开始进食。最后，我们得出结论，叶龄不仅影响母体昆虫寻找合适产卵栖息地的能力，而且还影响其后代的发育。
Adoxophyes honmaiYasuda (Lepidoptera: Tortricidae) is a serious pest of tea plants in Japan. Damage caused by larvae is widely distributed throughout tea plantations, but the modes of oviposition and offspring feeding are still unclear. Therefore, the objective of the present study was to determine oviposition preference for leaf age inA. honmaias related to performance of offspring. Two-choice experiments between young and old leaves showed thatA. honmaifemale adults preferred to oviposit on the area close to old leaves rather than young leaves. Therefore, volatiles from old tea leaves appear to act as attractants and stimulate oviposition. In contrast, more than 70 % of neonates fed on young leaves 24 h after starting the experiments, and development of larvae that continuously fed on young leaves was higher than larvae that fed on old leaves. After hatching, neonates likely move to the young leaves to start feeding. Finally, we conclude that leaf age affects not only maternal insect ability to find suitable habitats for oviposition, but also affects the development of their offspring.
