What eats the tops of potato plants?
Several leaf-eating worms — which are typically the larval stage of moths and butterflies — will feed on potato plants, leaving the top portion looking as if something has bitten it. Cutworms and armyworms, for example, are two such leaf-eating caterpillars measuring about 2 inches long that can infest your garden.
What eats holes in potato vine?
Usually less that 1/10 inch long, the adult beetles infest sweet potato vines in spring, chewing tiny holes in their new leaves, reports the University of California Statewide Integrated Pest Management Program. Although the leaf damage is seldom serious, damage from the beetles' root-feeding larvae might follow.
How do you get rid of aphids on sweet potato vines?
You can often control aphids by wiping or spraying the leaves of the plant with a mild solution of water and a few drops of dish soap. Soapy water should be reapplied every 2-3 days for 2 weeks.

What is going on? A: Small holes in early summer, in the leaves of any vegetable, are the hallmark of flea beetles. These beetles are about the size of fleas and they hop like fleas, so they usually remain invisible to gardeners. Fortunately, their appetites match their physical size.
How do you keep worms from eating sweet potatoes?
Worm Management The best way to manage them is to not plant sweet potatoes in infected soil. Wireworms are more likely to occur in soil that previously had clover or alfalfa crops. You can detect the presence of wireworms using bait made from carrots, pieces of potato and untreated corn.

How long does it take for potato bugs to hatch?
Female potato bugs lay orange-yellow eggs in clusters on the underside of the leaves on the host plants. Those eggs hatch in 4-15 days, depending on the external temperature. Then, those little larvae start to feed on the foliage for the next month.
What insects are in my garden?
Insects such as ladybugs, spined soldier bugs, lacewings, and nematodes feed on the eggs and the early larval stages. Nematodes attack the immature stages that develop in the soil.
Can potato bugs fly?
Overwintering beetles hibernate in the soil or garden debris until they emergy in the spring. At this point, the beetles cannot fly because they don’t have enough energy and must walk in the beds to find suitable host plants.
How do weevils affect sweet potato plants?
The sweet potato weevil is a serious pest in the field and in storage. Even low numbers of larvae reduce sweet potato quality and marketable yield. The adult weevil feeds on all parts of the plant but reproduces only in the stems and roots. Sweet potato weevils are most numerous close to the soil surface. Eggs are laid in the roots or stems in holes (one per hole) eaten out by the females. Following egg lay, the holes are covered by a grayish mass that hardens to form protective caps over developing eggs. Depending on environmental conditions, incubation of eggs varies from four to 56 days. Larval development occurs inside the root and can range from 12 to 154 days. Pupation occurs within the sweet potato, and this stage lasts for five to 11 days. Newly emerged adults wait one to three days before leaving the root. Adults mate soon after emergence from the root but egg laying does not occur for four to seven days. The injury from the weevil is from adults and larvae. The adult feeds on the root, puncturing numerous small holes and laying eggs in these punctures. Larvae tunnel throughout the root. All stages of the weevil can be found in the root. Larvae also tunnel through the vine next to the soil. Larvae found in the vine usually come from eggs deposited in the plant production bed. Sweet potatoes infested with weevils are not only unsightly, but they taste bitter.
What insects are in the sweet potato root?
The sweet potato root can be injured by several soil insects including: the sweet potato weevil, rootworms, wireworms, white grubs, whitefringed beetles and flea beetles. The sweet potato weevil larva is the only insect that tunnels throughout the root. Other soil insects feed on the surface of the developing root.
How to kill root worms in Louisiana?
Because this species has several generations per year, a wide host range and is very mobile as adults, it is one of the most difficult soil insect pests to control. Repeated cultivation of the fields in the spring will help remove alternate food sources and expose the larvae to birds and other predators. A preplant soil insecticide (Mocap, Lorsban) will kill rootworms in the soil and provide residual control for four to six weeks after application. Adult beetles moving into the field will lay eggs, and resulting rootworms will injure the roots once these soil insecticides break down. At this point, if adults exceed threshold levels, resort to foliar applications to prevent rootworm injury. Depending on environmental conditions, the insecticide used and the coverage obtained with the spray application, a foliar-applied insecticide may kill beetles for anywhere from one day to one week. Adult beetles can be monitored with sweep nets. Two banded cucumber beetles per 100 sweeps indicate the need to spray on a seven-day interval. With higher numbers of the beetle, reduce the spray interval to five days. These beetles are highly mobile. They may move into a field in large numbers and make management difficult.
What do armyworms eat?
These armyworms have a broad host range, feeding on many plants including several vegetable and field crops as well as weeds.
What are wireworms in sweet potatoes?
Several species of wireworms seriously injure sweet potatoes. Adults , known as click beetles, do not feed on the crop but oviposit on the soil near the crop, weeds or other vegetation. Wireworms have a very broad host range and will feed on weeds in the fields. Larvae produce small, round shallow feeding holes on the root surface. The original holes are usually less than 1/4 inch deep, but may be considerably deepened by later growth of the sweet potato root. The life cycle varies from species with two generations per year to species with life cycles lasting two to three years.
What is the name of the worm that injures sweet potato roots?
