| Abstract/Contents: | "Turf scientists from across the country are collaborating in the Northeast Regional Hatch Project 1025 to study the management of two important pests of annual bluegrass, anthracnose disease and annual bluegrass weevil (ABW). This article reviews ABW's biology, and points include: The annual bluegrass weevil, Listronotus maculicollis, (formerly called Hyperodes), principally feeds as larvae on annual bluegrass. With 2-3 generations per year, this weevil can build to astonishing populations (small patches may reach 800 larvae per square foot) that can stress or kill annual bluegrass in greens and fairways. The wide-spread use of pyrethroid insecticides has left many courses with adult weevils that are now virtually impossible to kill with any pyrethroid. Superintendents should be aware that the physiological changes due to pyrethroid resistance may also make some other insecticides less effective. When pyrethroid-resistant annual bluegrass weevil adults are exposed to piperonyl butoxide, their susceptibility to pyrethroids is restored. Among the non-pyrethroid products being confirmed as effective against ABW are trichlorfon (Dylox®), spinosad (Conserve®), chlorantraniliprole (Acelepryn®), and indoxacarb (Provaunt®). A study conducted over a three-year period on untreated fairways of three golf courses in New Jersey demonstrated that two species of entomopathogenic nematodes (Steinernema carpocapsae and Heterorhabditis bacteriophora) regularly infect ABW stages from the third larval instar through newly hatched adults. The low susceptibility of adults even under ideal laboratory conditions suggests that entomopathogenic nematodes are not likely to replace preventive chemical pesticides for adult control." |
