Quck answer
The potato bug, also known as the Colorado potato beetle, is a notorious pest that feeds on potato plants and other crops. It is difficult to control due to its resistance to many insecticides and ability to reproduce quickly. The larvae of the potato bug can cause significant damage to crops, leading to reduced yields and economic losses for farmers. Integrated pest management strategies, such as crop rotation and biological control, are effective methods for managing potato bug populations. However, continued research and development of new control methods are necessary to combat this super pest.
Wild animals
The Colorado potato bug, also known as the potato beetle, has been a menace to farmers and gardeners alike for the past two centuries. Despite the use of various chemicals and pesticides, this insect continues to thrive and cause widespread damage to crops around the world.
It is a universal truth that every living organism on Earth has its own set of problems. For instance, wolves prey on elk, while English ivy can strangle trees. Similarly, humans create problems for all other beings on the planet. The Colorado potato bug is a significant problem for humans because it feeds on the same crops that we rely on for food. This pest was first observed by European explorers in the early 1800s, and by the end of the century, it had destroyed fields of potato, eggplant, tomato, and pepper across North America and Europe. Today, this insect can be found in Asia as well, making it a global pest.
Potato Bugs Love Nightshade Plants
The Colorado potato bug is not just any ordinary pest; it is an iconic pest of modern agriculture. According to entomologist R.A. Casagrande, “This insect resulted in the first large-scale use of insecticides on an agricultural crop…influencing generations of agriculturists to depend upon this unilateral approach for managing this pest and others.”
Despite all our efforts, the potato bug has defied nearly every chemical and pesticide that we have developed to destroy it. Even substances as toxic as DDT have failed to eliminate this pest. Scientists believe that the insect’s tolerance to toxins in nightshade plants, which it consumes regularly, has made it resistant to many chemicals and pesticides.
The adult Colorado potato bug is about the size of a grown-up human’s pinky fingernail. It has a humped, hard shell with 10 orange and black vertical stripes running from head to tail. The larvae, on the other hand, look different, with a plump, red body and black spots on their sides.
Potato bugs feed on all parts of a plant, even burrowing underground in early spring to reach the parts that have yet to emerge. For home gardeners, handpicking the adult insects from plants early in the growing season can be an effective control measure. Later on, spraying insecticide or covering the plants with fine netting may help keep them at bay. Commercial producers, on the other hand, rely on a variety of insecticides and must rotate modes of action to prevent or delay the development of insecticide resistance. Additionally, farmers have found that rotating fields can reduce the risk of a potato bug infestation.
Potato Bug Life Stages
Potato bugs spend their winter under the soil, about 4 to 10 inches (10 to 25 centimeters) deep. In the spring, they emerge and start feeding on new crops or solanaceous weeds.
Female potato bugs emerge and mate, laying their bright orange eggs in clusters on the undersides of solanaceous plant leaves. A female can lay more than 500 eggs in the first month of spring. The eggs hatch in four to nine days, depending on the temperature, and the larvae start feeding on the leaves.
“Initially, the young larvae feed near where they hatch, but they spread out as they grow,” explains Bessin. “The larvae go through four growth stages in two to four weeks before dropping to the soil to pupate. The next generation of adults emerges in five to 10 days, and the cycle repeats for the next generation.”
Depending on the climate, multiple generations of potato bugs can occur in a single season. In Kentucky, where Bessin lives, two generations of potato bugs can emerge in one year.

Do not mistake the Colorado potato beetle for the false potato beetle, which has beige and black stripes and feeds on nightshades but not those in your garden.
FAQ
1. What exactly is a potato bug?
A potato bug is a type of insect that is also known as a Jerusalem cricket or a child of the earth. It is typically found in the western United States and Mexico. They are large, brownish-orange, and have a distinctive appearance that makes them easily recognizable.
2. Why are potato bugs considered super pests?
Potato bugs are considered super pests because they are incredibly difficult to control. They can cause significant damage to crops, gardens, and lawns, and once they infest an area, it can be challenging to get rid of them. They are also resistant to many types of pesticides and can survive in a variety of different environments.
3. How do potato bugs cause damage?
Potato bugs cause damage by feeding on the roots and stems of plants. This can cause the plants to wilt, turn yellow, and eventually die. They can also damage crops by feeding on the tubers of potatoes, which can reduce the yield and quality of the crop.
4. What are some natural ways to control potato bugs?
There are several natural ways to control potato bugs, including using diatomaceous earth, neem oil, or a garlic spray. These substances work by repelling the bugs or by interfering with their ability to feed on plants. Additionally, planting certain types of plants, such as marigolds or nasturtiums, can help to deter potato bugs.
5. What are some chemical methods to control potato bugs?
Chemical methods to control potato bugs include using pesticides such as carbaryl, chlorpyrifos, or imidacloprid. However, these chemicals can be harmful to humans and other animals, and may also have negative effects on the environment. It is important to use these chemicals carefully and only as a last resort.
6. How can I prevent potato bugs from infesting my garden?
To prevent potato bugs from infesting your garden, it is important to keep the area clean and free of debris. Additionally, you can plant certain types of plants that repel potato bugs or use natural methods of control, such as diatomaceous earth or neem oil. It is also important to rotate crops and avoid planting potatoes in the same area year after year.
7. Are potato bugs harmful to humans?
Potato bugs are not harmful to humans and do not bite or sting. However, they can be intimidating because of their large size and unusual appearance. It is important to handle them carefully and avoid touching them if possible.
8. Can potato bugs be kept as pets?
Some people do keep potato bugs as pets, but they require a specialized habitat and diet. They are not recommended as pets for most people because of their aggressive behavior and the difficulty of caring for them properly.
9. How long do potato bugs live?
Potato bugs have a relatively short lifespan of about one year. They spend most of their lives underground, where they feed on plant roots and other organic matter. They emerge from the soil in the late summer or early fall to mate and lay eggs.
10. Are potato bugs endangered?
Potato bugs are not considered endangered, but they are a protected species in some states. They play an important role in the ecosystem by breaking down organic matter and helping to aerate the soil. However, they can also be a nuisance for farmers and gardeners, which is why it is important to control their populations carefully.
