Borers are common in fruit trees and can do a lot of damage in a short period of time. Their existence is noticeable by the frass that is pushed out from the tree wood as the borer is entering.
Iris borer (Macronoctua onusta) is a pinkish caterpillar with rows of black spots on their sides. When full grown, it is about 2 inches long. The larvae emerge from the ground in April or early May when iris leaves are about 4-6 inches tall.

Borers, insects that develop underneath the bark of woody plants, attack many shade and ornamental trees. Most borers attack trees weakened by drought, mechanical injury, recent transplants, poor soils or root systems.
The borer tunnels through stems, disrupting the flow of water and nutrients. Damage first appears as sudden wilting of a long runner or an entire plant, even though the plants may be well watered.

Prevention is the best way to avoid problems, but it is sometimes difficult to keep these borers out, especially if organic methods are used. However, once the problem occurs it is possible to save the pumpkin.

Cane borers can be prevented by sealing the canes after pruning. Some rosarians use orange shellac, Elmer's[R] Glue or a cane sealer designed specifically for roses that's applied from a tube, like lipstick.
Cane borers are tiny caterpillar-like larvae that enter rose canes through tiny wounds and pruned stems, and then proceed to set up housekeeping. On occasion, they may enter the by actively boring into the cases.

Peach Tree Borers. The peach tree borer is the larval stage of a moth. The larvae bore into peach or plum trees close to the ground level. Heavily infested trees may be girdled, which will kill the trees.
Squash Vine Borer is also a major problem. This insect pest bores into the vine, usually near the tap root. Left unchecked, it eats right through the vine. Once it gets inside, the only way to kill it is to surgically remove it.

The cane borer makes itself known by a sudden wilting near the tops of new canes, where the adult beetle lays its eggs. If undisturbed, the larvae will travel down the cane, kill it, and infect others.
Recently introduced by accident in shipping materials and the like, insects such as Asian longhorned beetle, emerald ash borer, and hemlock woolly adelgid have already killed millions of trees and threaten many more.
The foremost insect pests targeting bearded iris are iris borers and aphids. Iris borers are best controlled through cultivation. Trimming away infested areas of the plant and removing dead foliage each fall can help reduce borer infestations.
Keep the soil moist the first year after planting, as drought-stressed trees can fall victim to borers. These pests are caterpillars that bore holes into the trunk, which "bleed" a sticky sap.

away from your crops as long as plants are completely covered and the edges are securely pinned to the ground. They’ll block aphids, potato beetles, Japanese beetles, grasshoppers, leaf miners, cabbage worms, root maggots, and some vine borers.
Few diseases bother the plant but Iris borers can eat up the roots. Cut away any rhizome that looks diseased or rotten, let it dry out of the ground for a day or two then replant the healthy root and fan.
Another problem is borer. Keep an eye out for the tell-tale dark holes on the stems, which sometimes weep if water is getting in, and the accumulation of white frass, which is actually fine "sawdust" that has been excreted by the grub.
Temperatures over 90F can cause buds and blossoms to drop; the condition is more serious if humidity is low also.
