Tarnished Plant Bug

A Comprehensive Guide to Identification, Damage, and Control

Tarnished plant bugs (TPBs) are a common pest of many plants, including vegetables, fruits, and ornamental plants. These bugs are small, about 1/4 inch long, and have a distinctive pattern of green and brownish-black markings on their wings. They are also known as lygus bugs or tarnished bugs.

Identification

To identify TPBs, look for the distinctive green and brownish-black markings on their wings. They may also be seen crawling or flying around plants, or they may be found in the crevices of leaves or buds.

Damage

TPBs cause damage to plants by piercing the plant tissue and sucking out the sap. This feeding can cause leaves to become distorted, stunted, or discolored, and it can also cause flowers or fruit to become deformed or drop prematurely. In addition, TPBs can transmit plant diseases, which can further harm plants.

TPBs are most active during the spring and summer months and are attracted to plants that are actively growing and producing new growth. They prefer to feed on the youngest, most tender parts of the plant, such as buds, shoots, and flower petals.

Natural Control Methods

  1. Encourage Natural Predators – One of the most effective ways to control TPBs is to encourage natural predators, such as ladybugs, lacewings, and predatory stinkbugs, to your garden. These insects will feed on TPBs and help to reduce their population. Planting native flowers and providing habitat for these beneficial insects can help to attract them to your garden.

  2. Neem Oil – Neem oil is a natural insecticide that can be effective against TPBs. It works by disrupting the insect’s hormonal balance and preventing it from feeding and reproducing. To use neem oil, mix it with water according to the package directions and spray it on the affected plants.

  3. Insecticidal Soap – Insecticidal soap is another natural option that can be effective against TPBs. It works by suffocating the insects and disrupting their cell membranes. To use insecticidal soap, mix it with water according to the package directions and spray it on the affected plants.

  4. Companion Planting – Planting companion plants that are known to repel TPBs can be a helpful strategy. Some plants that may be effective include marigolds, catnip, and tansy.

  5. Row Covers – Using row covers to physically block TPBs from accessing your plants can be effective, especially in the early spring when TPBs are most active. Row covers should be removed once the plants begin to flower to allow for pollination.

  6. Cultural Practices – Maintaining healthy plants through proper watering, fertilization, and pruning can help to reduce the damage caused by TPBs. Removing plant debris and weeds from the garden can also help to reduce the insect’s habitat.

Pest Management

If natural methods of control are not effective, chemical pesticides can be used as a last resort. It is important to choose a pesticide that is labeled for use against TPBs and to follow the application instructions carefully. Pesticides should be used sparingly and only as a last resort, as they can harm beneficial insects and pollinators.
