Marble bug (Halyomorpha halys Stal.) — this pest causes significant damage to agricultural crops, especially wheat, as well as fruit, vegetable, and leguminous plants. This insect has a characteristic brown or yellow-brown coloration with marble-like spots on the back and head, as well as rings on its antennae. The marble bug is a polyphagous pest, meaning it can feed on various plants, including green shoots, stems, leaves, fruits, and even weeds, leading to reduced yields and decreased product quality.
Damage caused by the marble bug appears as punctures on leaves, fruits, and bark, resulting in necrotic areas, bumps, and discoloration. In addition to direct damage, this pest acts as a vector for phytoplasma and other diseases, making it particularly dangerous for agricultural fields. The bug's activity increases during warm seasons, and it overwinters in specific locations, which facilitates its spread.
Control measures for the marble bug include a combination of mechanical, biological, and chemical methods. Effective insecticides based on bifenthrin and gamma-cyhalothrin, as well as pheromone traps, are commonly used. Phytosanitary inspection during the importation of goods is also important to prevent the pest's spread to new areas. Timely detection and a comprehensive approach to controlling the marble bug help reduce its negative impact on yields and maintain the quality of agricultural products.
