Sampling methods: no design,baited,other traps

Sample size: 259 individuals

Years: 2009, 2010

Days: 14

Nets or traps: 18

Net or trap nights: 252

Sampling comments: "Specimens were monthly collected from May, 2009 to April, 2010. Three sampling sites were established in each fragment with a distance of at least 200 m from the nearest edge in order to minimize the edge effects... and at least 400 m from each other. Each of the nine sites was monitored between 07:00 and 17:00 hours on a single day monthly, with a total sampling effort of 1,080 h. A passive collecting method (trapping) was employed using six types of artificial fragrance as baits-eucalyptol, eugenol, vanillin, methyl salicylate, benzyl acetate, and β- ionone. Eighteen traps were set at each fragment, from a height of 1.5 m above the ground. The traps were made with 2-l plastic soda bottles with three short, inverted funnels inside. A pendulum with a swab of cotton wool soaked in fragrance was fixed in the cap of the basal bottle"
