Observations on the Attack Caused by Eurygaster Spp. On Cereal Crops in the Moldova-Romania Area

The assessment of the damage caused by the Eurygaster spp. genus in wheat crops was carried out during the period 2020-2024, analyzing their impact on grain quality. In 2020, a significant attack was recorded in the localities of Comarna, Prisăcani and Dolhești, where most of the grains were affected, and the frequency of infestation varied between 0.1-1% and 3.1-4%. In 2021, the attack was more extensive, with a large number of grains affected, and the localities of Prisăcani and Dolhești recorded severe infestations, with over 80% of the production affected in the categories 2.1-3% and 3.1-4%. In 2022, a positive trend was observed in some areas, with a decrease in the intensity of the attack, especially in the localities of Comarna and Răducăneni. In 2023, the attack continued, but was less severe than in previous years, with a significant decrease in affected grains in the higher infestation categories. In 2024, a low level of infestation was recorded in most localities, with a decrease in severe attacks. The data suggest increased efficiency of control measures and less favorable conditions for pest development. However, the constant presence of attacks highlights the need for continued protection measures to limit the economic impact on wheat producers.
