| Abstract/Contents: | Discusses control of the annual bluegrass weevil (Listronotus maculicollis) (ABW). States that it "is a highly destructive pest of well maintained, short turfgrass in the northeastern United States...[and] turfgrass managers rely heavily upon the use of chemical pesticides to manage weevil populations from reaching damaging levels." Mentions previous testing of instecticidal compounds for their efficacy against ABW stating that "efficacy tests published between 1993 and 2003...[show] that pyrethroids were the most effective insecticides with no significant difference among the different compounds (bifenthrin, 93%; cyfluthrin, 87%; Deltamethrin, 84%; lambdacyhalothrin, 97%; overall average, 90%)." Also states that "to achieve the best ABW control rates, it is...recommended to apply pyrethroids against the overwintered adults between full bloom of forsythia and full bloom of flowering dogwood." Results indicate that "less hazardous chemistry appears to lack the efficacy and consistency to replace pyrethroid applications." States that a compound from the insecticide class, "the antranilic diamides, has shown great promise in recent trials with 80/95/84% control when applied in April/early May/late May." Also discusses the use of pesticide alternatives to control ABW. States that "entomopathogenic nematodes (EPN) have provided good to excellent control of various other weevil pests such as citrus weevils in citrus, black vine weevil in ornamentals, and billbugs in turfgrass. EPN also have the potential to provide control or more than one pest generation." Mentions 2005 testing of "EPNs that naturally infect annual bluegrass weevil." States that "soil samples were collected from historically ABW infested sites on 11 golf courses in 5 counties in New Jersey. Seven of the sites had ABW present in the samples and two of the sites contained larvae infected by EPNs. EPN-infected stages were late-instar larvae or pupae." Results include "98% were infected by Heterorhabditis sp. (probably bacteriophora) and 2% by Steinernema sp. (probably carpocapsae). EPNs were dected in the soil of 29% of all samples with 34% of isolates being Heterorhabditis sp...and 66% Steinernema sp." Also mentions a study monitoring "seasonal dynamics of ABW and native EPN" stating that "the course did not apply pesticides in the fairways to control ABW and consequently, large numbers of larvae and infected individuals were found in several areas across the course. Transects were established on three fairways in order to describe the relative abundance and distribution of ABW and endemic EPNs, as well as interactions between the two." Also states that "the ecology and spatial distributions of endemic EPN are poorly understood and epizootic outbreaks are rarely documented, however, such information could prove useful in the selection of biocontrol agents and development of future management plans." |
