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常用于保护苹果免受日灼损伤。遮阳网同时可作为物理屏障，阻止害虫昆虫定殖，并干扰害虫以及遮网果园中有意释放的昆虫的扩散行为。研究人员将不育苹果蠹蛾（*Cydia pomonella* (L.)）释放至设置遮阳网的商品苹果园中，对比其在2.4米高、6.1米高遮阳网下以及无网果园中的扩散情况。与开阔果园相比，两种测试网高处理下，释放的不育苹果蠹蛾的重捕率均受到抑制。当网高与果树冠层愈发接近时，种群聚集度随之升高。在两种网高处理的果园样地以及开阔果园的所有诱捕距离下，均能重捕到不育苹果蠹蛾，表明其扩散方向呈随机分布。本文还探讨了苹果蠹蛾不育昆虫技术与防护遮阳网的兼容性。
