Abstract/Contents:Insect traps baited with synthetic sex pheromones can be used to monitor adult insect populations in turfgrass. If the threshold number of captured adult insects which corresponds to damaging populations of larvae can be determined, then this type of population monitoring can be used to determine that an insect pest problem is imminent. Appropriate control measures can then be taken. The first step in developing this system is identification of the chemicals that insects use as sex pheromones. Identification of sex pheromones for bluegrass webworm, sod webworm, and northern and southern masked chafers is described. The most effective attractant for the bluegrass webworm consists of 95% (Z)-11-hexadecenal and 5% (Z)-9-hexadecenal. Sticky traps baited with this blend captured up to 82 moths per trap per night in a residential backyard. (Z)-9-tetradecenyl acetate and (Z)-9-tetradecenol have been identified as sex attractants for the sod webworm. At least one additional component must be involved. Efforts to identify the full pheromone blend for this species will continue in the coming field season. Using a bioassay system, chromatographic fractions that attract male masked chafer beetles have been isolated.
