Beet leaf miner mainly attacks spinach, beets, but also other plants of the Chenopodiaceae family (eg Amaranthus).
Scientific name: Pegomya hyoscyami
Other name: Spinach leaf miner
Greek name: Φυλλορύκτης των Τεύτλων
Grey, translucent areas appear on the leaves. Often between the epidermis of the upper and back surfaces of the leaf, larvae can be seen inside tunnels, feeding on the parenchyma. These tunnels later dry out and turn black.
The cotyledons are also affected, where the larvae open tunnels and may eventually cause the death of the seedlings.
The larvae are 6-8 mm long, whitish-yellow in color, without legs and lacking a head capsule.
The adults are 8 mm long, grey in color and have red eyes. They resemble the house fly.
The beet leaf miner insect is widespread in all beet producing areas. When infestation occurs in the early stages of the crop (up to the stage of 6-8 true leaves), control measures are indicated.
