Curtiss et al. Net Effect Dataset, 2023

<strong>ABSTRACT:</strong> Orchard shade netting is commonly used in Washington State to protect apples from sunburn. Shade netting may also act as a physical barrier to colonization by pest insects and may interfere with the dispersal of pest insects and those intentionally released under netted orchards. Sterile <em>Cydia pomonella</em> (L.) were released into commercial apple orchards with shade net to compare their dispersion under nets 2.4 m high, 6.1 m high, and in orchards without nets. Recapture of released sterile <em>C. pomonella</em> was suppressed by both tested net heights compared to open orchards. Population aggregation increased as net height and tree canopy became closer. Sterile <em>C. pomonella</em> were recaptured at all trap distances in orchard plots with both net heights and in open orchards indicating that their direction of dispersion was random. The compatibility of the sterile insect technique for <em>C. pomonella</em> and protective netting is discussed.摘要：果园遮阳网在华盛顿州被广泛用于防护苹果免受日灼危害。遮阳网可作为阻隔害虫定殖的物理屏障，同时能干扰害虫以及网棚下人工释放个体的扩散行为。本研究将不育苹果蠹蛾（*Cydia pomonella* (L.)）释放于设置遮阳网的商业化苹果园，对比其在2.4米高、6.1米高遮阳网及无网果园中的扩散情况。相较于无网果园，两种测试高度的遮阳网均抑制了释放的不育苹果蠹蛾的重捕回收率。种群聚集程度随遮阳网高度与果树冠层间距的缩小而升高。在两种高度遮阳网果园及无网果园的所有诱捕距离点均重捕到不育苹果蠹蛾，表明其扩散方向呈随机分布特征。本研究还探讨了苹果蠹蛾不育昆虫技术与防护遮阳网的兼容性。
