Oak lace bug – Corythucha arcuata (Say, 1832) (Hemiptera: Tingidae) is a North American species that has been introduced to Europe and Asia, where it became a serious oak pest. As little is known about its behavior, we conducted a study in which we tested the preference and performance of the oak lace bug for different oak species and the influence of powdery mildew and CO2 on the behavior of the oak lace bug. Four of the most represented oak species in Serbia (Hungarian, pedunculate, sessile, and Turkey oak) were used for testing the preference and performance of the oak lace bug, and the influence of oak powdery mildew on the behavior of the oak lace bug. The influence of CO2 on the behavior of the oak lace bug was tested on pedunculate oak. The results of this study have shown that there are differences in preference and performance of the oak lace bug between the analyzed oak species; there are significant differences in the oak lace bug host preference in the laboratory and in field conditions; Hungarian oak is most threatened by the oak lace bug, as the oak lace bug performs best on this species and preferers this species in field conditions; the oak powdery mildew and oak lace bug are in an antagonistic relationship; and that the changes in the leaves caused by the expected increase in CO2 concentration in the future will probably not influence the feeding behavior of the oak lace bug adults.

影响橡树花边虫（半翅目：Tingidae）行为的因素：喂养偏好并不意味着更好的表现？

橡树花边虫 – Corythucha arcuata (Say, 1832)（半翅目：Tingidae）是一种北美物种，已被引入欧洲和亚洲，在那里它成为一种严重的橡树害虫。由于对其行为知之甚少，我们进行了一项研究，测试了橡木花边虫对不同橡树品种的偏好和性能，以及白粉病和二氧化碳对橡木花边虫行为的影响。塞尔维亚最有代表性的四种橡木（匈牙利橡木、有花梗橡木、无梗橡木和土耳其橡木）被用于测试橡木花边虫的偏好和性能，以及橡木白粉病对橡木花边虫行为的影响。在有花梗的橡木上测试了二氧化碳对橡木花边虫行为的影响。这项研究的结果表明，所分析的橡木品种之间对橡木花边虫的偏好和表现存在差异；在实验室和田间条件下，橡木花边虫的宿主偏好存在显着差异；匈牙利橡木最容易受到橡木花边虫的威胁，因为橡木花边虫在该物种上表现最好，并且在野外条件下更喜欢该物种；橡树白粉病和橡树花边虫是对立的关系；并且未来预期的二氧化碳浓度增加引起的叶子变化可能不会影响橡树花边虫成虫的摄食行为。匈牙利橡木最容易受到橡木花边虫的威胁，因为橡木花边虫在该物种上表现最好，并且在野外条件下更喜欢该物种；橡树白粉病和橡树花边虫是对立的关系；并且未来预期的二氧化碳浓度增加引起的叶子变化可能不会影响橡树花边虫成虫的摄食行为。匈牙利橡木最容易受到橡木花边虫的威胁，因为橡木花边虫在该物种上表现最好，并且在野外条件下更喜欢该物种；橡树白粉病和橡树花边虫是对立的关系；并且未来预期的二氧化碳浓度增加引起的叶子变化可能不会影响橡树花边虫成虫的摄食行为。
