Knife, Pot, Tent, and Fishing Rod (assuming is comes with line and hooks/tackle.)

Tarp is probably more versatile than the tent. But if the insects are bad, having the reprieve of an enclosed shelter is appealing. Edit: The more I think about it, the tent is far more versatile than the tarp. As it can still be used as a tarp to collect water. It also likely comes with cordage and stakes. So its kind-of a no-brainer.
