Minor black bugs on tomato plants may not seem like much of a problem, but they can quickly become serious if left unattended. These pests probably belong to a family of insects called flea beetles. Controlling them can be done in several ways, though a pesticide may be necessary.

In addition to aphids and flea beetles, several pests often attack tomatoes.

  • Anthracnose is an infection spread by aphids that feed on tomatoes. 
  • This pinhead-sized insect can also transmit the virus to your tomato plant. You can identify different types of aphids based on their color (black, pale green, and pink).
  • Yellow and curled leaves are the symptoms.

What are the best ways to control aphids? Wear gardening gloves after wiping black bugs with string streams of water or with your hands. The use of horticultural oils is considered effective in controlling pests.

Additionally, you can grow companion plants that repel insects and aphids. Of course, you can grow your army of aphids to combat them. Your garden is protected from black bugs by insects like lady beetles and soldier beetles.

Taking specific steps will increase your tomato harvest, but ignoring them will result in fewer tomatoes.

  • Steel cylindrical cones are ideal for supporting tomato plants. The cage provides support while elevating branches and leaves. It also prevents blossom ends from rotting.
  • Plant herbs such as basil, cabbage, marigolds, and nasturtiums to keep aphids and flea beetles away from tomato plants.
  • Pull weeds surrounding your tomato plant to keep them from feeding on aphids or black bugs.
  • Using gardening gloves, you can pick up giant insects, but spraying natural pesticides will eliminate small, black insects.

Aphids are tiny insects about a pinhead and have colors ranging from white to pink, pale green to black. Aphid infestations cause plants to wilt, curl, and turn yellow. Aphids, which feed on tomatoes, cause sooty mold when they sap from the plants and secrete honeydew. 

Soldier beetles, lady beetles, syrphid flies, and lacewing larvae are beneficial insects controlling aphids. You can easily remove aphids on leaves by spraying them with water or rinsing them with a wet cloth.

Applying a bar of insecticidal soap will also be beneficial, but it requires thorough coverage of the foliage, and it may require multiple applications. Aphid eggs can be overwintered with horticultural oils.

Significance

In general, these bugs are a threat to tomato plants because of the damage they cause. In addition to defoliating plants, the beetles could expose them to blight and disease, fatal.

Usually, black or brown flea beetles are less than half an inch long. Even tenths of an inch can make a difference.

Even if a beetle was as giant as a tomato plant, it could not cause much damage to it, but they are often found in groups.

Prevention/Solution

Beetles will quickly leave a site if they cannot find nourishment. Nevertheless, if there are other food sources nearby, they might stay. It may discourage tomato beetles from establishing a colony by delaying tomato planting.

A permethrin-based insecticide, carbaryl-based insecticide, spinosad-based insecticide, or bifenthrin-based insecticide can effectively destroy populations. These treatments should be repeated weekly to prevent the problem from returning, especially young plants.

A winter’s worth of shelter in the soil is usually sought by adult beetles, emerging again when temperatures reach 50 degrees.

There can be as many as three generations of beetles in a growing season, and they multiply continuously.

Time Frame

Generally, flea beetles are between black and brown, with a length of less than half an inch; some are even smaller than that, even smaller than a tenth of an inch. Several beetles can infest a single plant. If disturbed, the beetles can jump an impressive distance using their well-developed hind legs.

Adult beetles emerge from the soil when the temperature reaches about 50 degrees. These insects seek food immediately after emerging and continue their life cycle.

The beetles can produce up to three generations in a growing season, multiplying each time. Some beetles produce many generations each year in locations with extended growing seasons.

Summary

Now you know all about minor black bugs on tomato plants. Aphids are tiny, winged, or wingless insects that feed on plants’ leaves or clusters of leaves throughout vegetation. Aphids are sometimes challenging to see, but if ants are present, they are usually present. (Aphids leave honeydew behind that ants like to feed on.)

Aphids are sap-sucking insects that cause plants to weaken and stunt their growth. With a Thumb Control Watering Nozzle, you can use a heavy stream to knock off aphids from tomatoes. Follow up by spraying soapy water on the plants.

What Are The Effects Of Aphids On Tomato Plants?

Despite high numbers of aphids, tomato plants don’t suffer yield losses. However, the plant may become stunted when leaves curl due to severe infestations. Fruits may be scalded by increased sun exposure if the leaf area is decreased. Some plant viruses are transmitted by aphids as well.
