Squash vine borer
"Organic controls include wrapping the lower stem with nylon stockings or aluminum foil to prevent egg laying, which generally occurs within a couple inches from the point where the stem emerges from the soil. Row covers can be used up until bloom. An old gardener trick for vining squash and pumpkin is to cover the vine with earth at various points along its length, inducing rooting at several points, thereby continuing to feed the developing fruit despite the loss of the original stem. It may be noted that after the vine has taken root at multiple points, the infected portion of the plant can be cut off, along with another inch where the larvae is eating into healthy tissue, without significant damage to the plant. Once larvae are present within the stems control must be quick. Often the first noticed sign of the problem is wilting of the vine, and it is too late for control efforts at that point. Experienced gardeners watch the stems for signs of frass protruding from small holes, which is a giveaway to the presence of the larva inside. Some gardeners carefully cut the stem along its axis and remove the caterpillar before it does too much damage. Others use a stiff wire, a needle, or a toothpick to kill the borer without too much damage."
