Oriental mole cricket

Systematic position. The Oriental mole cricket (Gryllotalpa orientalis) belongs to the order Orthoptera and the family Gryllotalpidae. It is a robust subterranean insect highly adapted to burrowing, commonly found in moist soils across Eastern Asia and other regions.

Crops and damage. This pest is a polyphage, meaning it feeds on a wide range of plants, including vegetables, cereals, and turf. It causes damage by chewing through roots and stems just below the soil surface, leading to the rapid wilting and eventual death of young seedlings and established plants alike.

Biology and life cycle. The life cycle consists of the egg, nymph, and adult stages. Mole crickets spend the majority of their lives underground, preferring fertile, moist soil environments. Adults hibernate deep within the soil during colder periods and become active in the spring when the soil warms, emerging to feed and mate.

Economic impact. The Oriental mole cricket is highly destructive due to its digging activity, which destroys root structures and disturbs soil aeration. In high-density infestations, it can lead to complete failure of crop stands, significantly reducing yields and impacting the profitability of vegetable plots and agricultural fields.

Control measures. Managing this pest requires an integrated pest management approach:

• Deep plowing or tilling to destroy underground tunnel networks.
• Use of poison baits containing insecticides placed near tunnel entrances.
• Application of soil-incorporated granules during the planting season.
• Trapping techniques using organic materials to attract and collect the crickets.
