Short-winged mole cricket

Systematic position: The short-winged mole cricket (Scapteriscus abbreviatus) belongs to the order Orthoptera and the family Gryllotalpidae. It is a specialized soil-dwelling insect recognized as a significant pest, particularly in regions where environmental conditions support its reproductive cycle and digging activity.

Host plants: This pest predominantly infests turfgrass, including golf courses, athletic fields, and residential lawns. Furthermore, it causes substantial economic damage to various agricultural and ornamental plants. It targets the roots of vegetables such as tomatoes, peppers, potatoes, and various seedlings, leading to reduced crop yields.

Biology and life cycle: The life cycle encompasses egg, nymph, and adult stages. As the name suggests, adults have abbreviated wings, which restricts their dispersal capabilities compared to other species of mole crickets. They prefer moist soil environments to construct their underground chambers, where the females guard the eggs until hatching occurs.

Nature of damage and pest status: The damage is primarily caused by the tunneling behavior of the crickets. By moving through the top layers of soil, they sever root systems and disrupt the contact between roots and soil particles. This results in the browning and eventual death of turfgrass, as well as the wilting and loss of young plants in agricultural fields.

Protection measures: Integrated pest management (IPM) is essential for effective control. This includes regular mechanical cultivation of the soil to disturb cricket tunnels and nesting sites. Chemical control involves the strategic application of granular insecticides or toxic baits containing active ingredients like fipronil, specifically timed during periods of high nymphal activity.
