Listronotus bonariensis
This small, greyish-black weevil is a major pest of turfgrass, particularly in cool-season species like perennial ryegrass and bentgrass. The larvae burrow into the base of stems, killing tillers and causing patchy turf damage. Adult weevils also feed on leaves, exacerbating stress on the grass. Infestations often start in spring, with damage peaking in summer. Monitoring and insecticidal treatments can help manage outbreaks.
