1.Corythucha marmorata(半翅目：Tingidae)在其寄主植物黄花(Solidago Altissima)的小实验斑块中的数量比在同一地区的大斑块中更丰富。成虫和卵块在斑块边缘的茎上比在内部的茎上更丰富。笼养在边缘植物上的雌蜂比笼养在内部植物上的雌蜂产卵更多，暴露在裸露植物上的卵比在步幅中间的更快发育。对边的偏好会导致对面片大小的负“响应”，因为大面片总是比小面片具有更低的边比例。
1. Corythucha marmorata (Hemiptera: Tingidae) was more abundant in clusters of small experimental patches of its host plant, goldenrod (Solidago altissima), than in large patches covering the same area.2. Adults and egg masses were more abundant on stems on the edges of the patches than on those in the interior.3. Female C.marmorata caged on edge plants laid more eggs than females caged on interior plants, and eggs on exposed plants developed faster than those in the middle of a pacth.4. A preference for edges results in negative 'response' to patch size because large patches invariably have a lower proportion of edge than small patches.
