Controlling the interaction of insect populations with their host plants has recently received renewed attention in the light of pest control. One way to modify the interaction of insects with their host plants in a non‐chemical way is through influence of their de/attachment. Insect detachment has been observed for textured biological and structured artificial surfaces with morphologies ranging from nano‐ to micrometers (0.3–1.5 µm). Here, the formation of design surfaces is investigated through plasma‐induced polymerization of acrylates. This produces pronounced surface wrinkles that are tunable by the manufacturing process. For certain parameters, the wrinkles resemble those of the adaxial side of rubber tree (Hevea brasiliensis) leaves, a natural example of particularly low friction. Traction force measurements on the bio‐inspired surfaces show significantly impacted insect attachment compared to flat surfaces of silica and polymeric materials, opening a pathway to the controlled manufacture of bio‐inspired slippery surfaces for insects that could potentially find use in advanced materials such as wall coatings.

聚合诱导的起皱的表面，具有受控的地形，作为科罗拉多马铃薯甲虫的光滑表面
鉴于害虫控制，控制昆虫种群与其寄主植物的相互作用最近受到了新的关注。以非化学方式改变昆虫与其寄主植物相互作用的一种方法是通过其脱附作用。已经观察到具有纹理的生物和结构化人工表面的昆虫脱离，其形态范围从纳米到微米（0.3–1.5 µm）。在这里，通过等离子引发丙烯酸酯聚合来研究设计表面的形成。这会产生明显的表面皱纹，该皱纹可通过制造过程进行调整。对于某些参数，皱纹类似于橡胶树（巴西橡胶树）的背面）树叶，这是摩擦力极低的自然例子。与二氧化硅和聚合物材料的平坦表面相比，在生物启发表面上的牵引力测量显示，昆虫附着受到了显着影响，这为受控制造昆虫生物启发的光滑表面开辟了一条途径，该昆虫可能会在高级材料（如墙壁）中使用涂料。
