Insects That Eat Potatoes. Several insects are guilty of attacking potato plants and tubers. Pest infestations can be identified by the type of damage done and by direct observation of insects.

    Paper or books that have holes, missing corners and skinned areas are signs that paper-eating insects are present. Evidence of paper-eating insects includes empty egg cases, skin casings shed by larvae, dead insects and a powdery, sawdust-like substance on bookshelves or near damaged paper. Paper-eating insects are. Pests were out in force, he says, feeding on foliage or pods. The rogue pests caused aborted pods, and in some cases allowed viruses to take hold. Both, Craigmyle says, reduce yield potential. Types of insects When it comes to soybeans there are three main types of insects — foliage feeders, pod feeders and stem feeders.

Aphids can be problematic pests in wheat. There are several species of aphids in wheat fields. These include the English grain aphid and the bird-cherry oat aphid. Different species have different life cycles. Aphids do little direct damage to wheat plants but can be problematic due to transmission of viruses.

Wood boring insects are seen as pests due to the damage they create in both urban and rural areas. Within an urban environment wood boring insects can cause a huge amount of damage to residential properties.

While in agricultural and rural settings, wood boring insects are responsible for damaging crops, particularly fruit and forest trees. Introduce predatory insects that feed on spider mites, such as lady beetles, praying mantises and assassin bugs.

Or try this remedy from Garden Writers Association Hall of Famers Doc and Katy Abraham, authors of The Green Thumb Garden Handbook: mix 1/2 cup buttermilk and 4 cups of wheat flour with 5 gallons of water.

Hosts of the common stalk borer include such crops as corn, fruits, other vegetables, and flowers. The larvae feed on leaves or burrow into the stem of the plant making the plant appear wilted or deformed with visible holes on the leaves and stems.

Wheel bug. At inches in length, the wheel bug is one of the largest terrestrial true bugs in North America.

The most noticeable physical characteristic of the insect. Cut ventilation holes in the lid, and cover these with fine mesh screen (fasten with a glue gun). Put a 2-centimeter layer of clean soil in the bottom of the container, and cover the soil with a 2-centimeter mixture of crushed cornflakes, cornmeal, three or four 1-centimeter-thick slices of potato or squash, used birdseed, and/or wheat bran/chaff.

Plus, it keeps killing insect pests and protecting for up to three months. Sevin ® Insect Killer in ready-to-use, ready-to-spray and concentrate liquid forms also treats more than types of lawn and garden pests, including damaging moths and beetles.

The wheat stem maggot passes the winter in the larval stage, in the lower parts of the stems of wheat and other hosts. They pupate in the spring and the adults emerge in May. Eggs are laid singly on the leaves near the stem.

These eggs hatch into green colored maggots which feed inside the stem of the upper most joint of the host plant. At first glance, these tiny, black bugs look like poppy seeds to the naked eye. All it takes, however, is magnifying glass to see these insects clearly.

The larvae, on hatching, burrow into the stem, pupate, and soon mature, the adults emerging in the latter part of.infested with each pest was recorded.

The percentage of parasitized wheat stem sawfly larvae also was noted. The wheat stem sawfly, wheat stem maggot, and Hessian fly were the most commonly encountered pests, recorded in nearly every county.

Wheat stem sawfly density was twice that of wheat stem maggot (7% vs %) in infested fields.
