We encounter the flea beetle insect mainly on beets. The larvae of the insect live below ground and attack plants in the underground part. The adult of the insect cause damage to the aboveground part of the plant.
Scientific name: Chaetocnema sp., Haltica sp.
Greek name: Άλτης ή ψυλλός
Because of the damage to the emerging seedlings, empty spaces appear in the field. Small round holes with a gray margin are caused in the cotyledons and the first true leaves to make them look like “sieve”.
The larvae of Flea beetle are about 4 mm long and white in color. The adults (beetles) are about 2 mm long and dark in color with a metallic sheen. The shells have a pattern of small dents like spots on them. They are jumping insects.
The larvae live below ground and damage plants underground. In contrast, damage to the aboveground part of the plant is caused by the adult. Infestation is favored by dry weather.
