What Is Potato Bug & How To Identify Them

The name Potato bug itself is a little misleading. This is mainly applied to 2 types of bugs. Here, we use different names to help you identify correctly.

Colorado Beetles (Leptinotarsa ​​Decemlineata) and Jerusalem Cricket (Stenopelmatus Fuscus) can quickly infest the garden. In addition, they cause damage to valuable vegetable plants.

These two insect pests are named after the diet they like. They like to eat various plants in the park including different potato parts such as leaves, roots, and tubers. That’s why they called Potato bugs.

Colorado Beetles

As the name showed, this pest was first discovered in 1859 partying on potato plants in Colorado. Then, they spread throughout the United States of America quickly.

Now, the birth of Colorado potatoes was found in Alaska, Hawaii, Asia, and Europe. They become a serious pest for the commercial vegetable industry and home gardeners.

These potato bugs usually overwinter underground. Talking about their life cycle, usually starting in spring once the egg has been placed.

Female beetles lay eggs around 30 orange eggs and attach them to the bottom leaves with their yellow sticky excretion. They take 14 days to hatch. Once the bug hatches, they chew on plants.

In addition, larvae continued to grow for about 2 weeks and turned into pupa. Throughout their lives, the birth of females lay up to 900 eggs. In general, this pest appears around the same time, plants begin to surface.

The process may take around 30 days between pupae that transform into adults and eggs. This is very dependent on the local weather. A cooler climate can definitely block 2 more weeks.

Which is not mature to be an adult later on. After that, they mate and produced more eggs. Within one year, there will be three generations of Colorado potato beetles.

Jerusalem Crickets

Regardless of their name, they are not actual crickets. These potato pests are included in the order of insect equally orthoptera and Stenopelmatidae.

Unlike real mole crickets, this pest is not chirping. They created his hissing sound using their back legs in the middle of the body to repel the predator.

During the mating period, Jerusalem Crickets sang songs like grasshoppers. They beat their bodies to the surface, creating a unique drum sound to attract the attention of the mate partners.

Interestingly, crickets Jerusalem women usually eat their mates after completing the mating process. Next, the eggs will be placed in shallow soil holes.

  • Older larvae pink to salmon-colored with a blackhead.
  • All larvae have two rows of dark spots on each side of their bodies.
  • Old larvae are responsible for 75 percent of the damage to feeding.
  • Potatoes can usually tolerate defoliation up to 30 percent when they are in the vegetative stage.
  • They are far more sensitive when tubers start to bulk and they can only tolerate about 10 percent defoliation.
  • Bulking tubers begin immediately after flowering, making this time important for beetle management.

Potato bug bite

Both potato bugs are not dangerous, but the cricket Jerusalem can give people painful bites when restless. That’s the reason you don’t have to disturb them. Let the pest escape.
