Field trapping trials were performed at Revingehed near Lake Krankesjön, at 20 different field trapping sites (replicates) identified only by numbers 1-20. Treatments compared comprised two different baits: Dienol (p-Mentha-1,3-dien-9-ol dissolved in isopropanol) and Control (isopropanol only). Table columns: Year, Set date, Emptying date, Ordinal date, Trap site, Treatment (Dienol or Control), Total catch, Catch males, Catch females. 2) Catch_data_ California_ Holopleura_marginata This is an Excel file containing the original field trapping data for Holopleura marginata and other species in California. Field trapping trials were performed at four different sites in northern California: 1) Slaughterhouse Ravine, Magalia, Butte Co. (Magalia), 2) Rattlesnake Creek at Forest Road 27N12 (Rattle), 3) Junction Forest Roads 27N06 and 27N12Y (Rd27), 4) Whispering Pines Pet Clinic property, Magalia, Butte Co. (Whisp). Treatments compared comprised four different bait types with active components dissolved in isopropanol: Dienol (p-Mentha-1,3-dien-9-ol), Alcohol (2-(4-methylphenyl)-1-propanol = p-cymen-9-ol), 1:1 blend of the former, and Control (isopropanol). Table columns: Site, Species code, Date, Ordinal date, Total catch, Dienol catch, Alcohol catch, 1:1 blend catch, Control catch, Catch Genus, Catch species, Notes.
