2024年美赛模拟题——斑点灯笼蝇（Spotted Lanternflies）

题目介绍

If you spot a lantern fly... 

Spotted lanternflies(Lycorma delicatula) are insects from Asia that are quickly spreading in North America and have a growing negative effect on agricultural production, Since their arrival to the USA about ten years ago, they have now spread to at least 16 states(PA, NY,NJ, MD,MI, OH, IN, WV, VA, NC, DE, CT, RI, MA, KY, TN). These insects are particularly dangerous for grapevines, which is becoming a major concern for many vineyards and wineries present in NY State. Spotted lanternflies feast on plant’s sap and remove so much of it that the vine has far lower chances of surviving the cold temperatures. Even if a seriously affected vine survives, it is much less likely to produce any grapes next season. Qu
