What Are The Little Bugs on My Edamame Plant

Updated: October 31, 2022

If you’re growing edamame in your garden and notice small bugs crawling on the leaves, you may be wondering what they are and if they pose a threat to your plants. The good news is that many of the bugs you’ll see on your edamame plants are actually beneficial insects that help keep pests at bay. However, there are a few pesky critters that can cause damage to your plants if left unchecked. In this article, we’ll take a closer look at the little bugs on your edamame plant and what you can do to keep them under control.

Beneficial Insects

Before we dive into the problematic bugs, let’s talk about the beneficial insects you’re likely to see on your edamame plant. These tiny creatures are your garden’s natural pest control squad, and they help keep harmful insects from munching on your plants.

Ladybugs

Ladybugs are perhaps the most well-known beneficial insect. These cute little beetles feed on aphids, mites, and other soft-bodied insects that can damage your plants. You’ll often see ladybugs congregating around a colony of aphids, happily chowing down.

Lacewings

Lacewings are another beneficial insect commonly found in gardens. These delicate-looking insects have lacy wings (hence their name) and feed on aphids, mealybugs, and other soft-bodied insects.

Parasitic Wasps

Parasitic wasps may sound scary, but they’re actually harmless to humans and incredibly helpful in the garden. These tiny wasps lay their eggs inside pest insects, like caterpillars or aphids. When the eggs hatch, the young wasps feed on the pest from the inside out, eventually killing it. This may sound gruesome, but it’s an effective way to control pest populations without using harmful chemicals.

Problematic Bugs

While beneficial insects can help keep pests under control, there are a few types of insects that can cause real damage to your edamame plants.

Bean Leaf Beetles

Bean leaf beetles are a common pest of soybeans, including edamame. These beetles are about 1/4 inch long and have a distinctive coloring of yellow and black or red and black. They feed on the leaves of the plant, leaving behind small holes and chewed-up edges.

Stink Bugs

Stink bugs are another pest that can cause damage to your edamame plants. These shield-shaped bugs feed on the pods of the plant, causing them to become deformed and stunted. They also release a foul odor when disturbed, hence their name.

Japanese Beetles

Japanese beetles are a destructive pest that feeds on the leaves, flowers, and fruit of many plants, including edamame. These beetles are about 1/2 inch long and have a metallic green body with coppery wings. They skeletonize the leaves of the plant, leaving behind only the veins.

Control Methods

So what can you do to keep these pesky bugs from damaging your edamame plants? Here are a few control methods to consider:

Hand-Picking

If you only have a few pests on your plants, you can try hand-picking them off. This may not be the most pleasant task, but it’s an effective way to control small populations.

Insecticidal Soap

Insecticidal soap is a safe and effective way to control many types of garden pests, including aphids, mites, and bean leaf beetles. You can buy insecticidal soap at your local garden center or make your own by mixing dish soap with water.

Neem Oil

Neem oil is another natural insecticide that’s effective against many types of pests. It works by disrupting the insect’s hormonal system, eventually causing it to die. Mix neem oil with water and spray it on your plants to control pests.

Row Covers

Row covers are a physical barrier that can prevent pests from reaching your plants. Cover your edamame plants with row covers before the pests arrive to keep them at bay.

FAQ

Can I eat edamame that has been treated with insecticide?

No, it’s not safe to eat edamame that has been treated with insecticide. Make sure to follow all instructions on any insecticides you use and wait the recommended amount of time before harvesting your edamame.

How can I attract beneficial insects to my garden?

Planting a diverse range of plants in your garden can help attract beneficial insects. Flowers like marigolds, zinnias, and sunflowers are particularly attractive to ladybugs and other beneficials.

Should I remove beneficial insects from my garden?

No! Beneficial insects are an important part of your garden’s ecosystem and help keep pest populations in check. Don’t remove them unless you have a serious pest problem that needs to be addressed.

Can I use chemical pesticides on my edamame plants?

While chemical pesticides can be effective at controlling pests, they can also harm beneficial insects and pollinators. Try natural methods first before resorting to chemical pesticides. If you do use them, make sure to follow all instructions carefully and dispose of any unused chemicals properly.

In conclusion, the little bugs on your edamame plant may seem like cause for concern, but many of them are actually helpful in the garden. By understanding which bugs are beneficial and which ones can cause damage, you can take steps to keep your edamame plants healthy and pest-free. Happy gardening!
