2 of my scallop squash plants have died, and when I pulled them up, I noticed that the very base of them stem was soft. I pulled it open and the inside looked like sawdust. Inside the one plan were 3 little black beetles. In the other plant was a whit grub (quite small and thin) with a black head.
Do you think these are the culprits for the dead squash plants? Can anyone give me a hand in identifying them?
Thanks a lot!
