Pangaeus

The genus Pangaeus belongs to the family Cydnidae (burrowing bugs), within the order Hemiptera. These insects are a specialized group of pests that live primarily in the soil, which is why they are commonly referred to as burrowing or ground bugs.

The range of crops attacked by these insects is quite broad. Pangaeus is frequently found in cereal grains, maize, sorghum, as well as several vegetable and melon crops. Damage occurs mainly during the early growth stages of plants, when they are most vulnerable to mechanical injury to their subterranean organs.

The biology and life cycle of the species are characterized by a close association with the soil environment. Adults and nymphs overwinter deep in the soil or under plant debris. In the spring, as soil temperatures rise, the bugs become active and begin to feed on roots and the base of young plant stems, extracting cell sap.

The damage pattern manifests as stunted plant growth, yellowing leaves, and often the complete death of seedlings. Injured root tissues provide an entry point for pathogens, which further weakens the crop. The pest is highly cryptic, so farmers often notice the issue only after observing patches of thin or dead crops.

• Strict adherence to crop rotation by excluding host species.
• Thorough soil cultivation to disrupt overwintering sites.
• Use of insecticidal seed treatments.
• Effective weed control to reduce refugia.
• Regular monitoring of population density via soil sampling.

Control strategies require an integrated approach combining agronomic and chemical practices. It is crucial to maintain high agronomic standards that promote rapid root system development, allowing plants to compensate for minor damage. In cases of high population density, the use of systemic insecticides during vegetation or as a seed treatment is justified.
