Identification and damage
Atomaria is a small brownish-brown beetle, about 1.5 mm long, harmful to the chard in the early stages of development. In fact, it makes circular erosions at the level of the collar of the seedlings about 1 mm below the ground level, the seedlings collapse and there is a failure; more rarely it performs leaf erosions.
Linsetto winters as an adult and is 2-3 generations a year.

The fight against Atomaria is carried out, together with other beet greens, through the geo-disinfestations carried out during sowing.
