Abstract:Male Telrallychus urticae Koch are attracted strongly to quiescent deutonymphs and will remain until emergence of the adult female, when mating occurs. In laboratory bioassays, males were attracted to 1.5 µ liters of crude ether extract of quiescent deutonymphs containing 0.01 deutonymphs per ml of solvent. Male attraction varied over the range of concentrations tested. Strongest attraction occurred at 1.0 deutonymph equivalents per ml with decreased attraction at the higher and lower concentrations. Tests were conducted on detached hop leaf discs placed upon moist absorbent cotton. A clump of moistened finely ground polyvinylpyrrolidone powder served as the best of several tested substrates for the crude extract. Male attraction was measured as a percent of responses to treated sites and corrected for occasional visits to untreated check sites. Male response averaged 37.2% (range 0-73.6%) for 1.5 µ liters of extract per test site. Further refinement in bioassay procedure s necessary to aid in the identification of the attractant.
