Q: My pumpkin and squash vines started to wilt. I investigated the plants and found a white grub inside the vine. Do you know what it is and how to prevent it next year? I think some of the vines are going to survive, so that is good news.
A: Good work on finding the larvae of the squash vine borer. There are four life cycle stages to the squash vine borer: egg, larva, pupa, and adult. The adults are clearwing moths that fly in the daytime resembling a wasp.
