Keiferia lycopersicella

Keiferia lycopersicella, commonly known as the Tomato Pinworm, is a species of moth in the family Gelechiidae. It is native to North America and is considered a significant pest of tomato crops.

Description

The adult Keiferia lycopersicella is a small, gray moth with a wingspan of approximately 8-10mm. The larvae are yellowish-white with a brown head and can reach up to 8mm in length. The pupae are brown and approximately 5mm long.

Life Cycle

The life cycle of Keiferia lycopersicella consists of four stages: egg, larva, pupa, and adult. The female moth lays her eggs on the underside of tomato leaves. The larvae hatch and feed on the leaves, stems, and fruit of the tomato plant, causing significant damage. The larvae then pupate in the soil or on the plant itself. The adult moths emerge and the cycle begins again.

Distribution and Habitat

Keiferia lycopersicella is native to North America, but has been introduced to other parts of the world, including Europe and Asia. It is commonly found in tomato fields and greenhouses.

Pest Status

As a pest, Keiferia lycopersicella can cause significant damage to tomato crops. The larvae feed on the leaves, stems, and fruit of the tomato plant, causing defoliation and fruit damage. This can result in significant yield loss for farmers.

Control

Control of Keiferia lycopersicella involves a combination of cultural practices, biological control, and chemical control. Cultural practices include crop rotation and sanitation. Biological control involves the use of natural enemies, such as parasitic wasps. Chemical control involves the use of insecticides.
