Baited and unbaited
minnow traps were occasionally deployed opportunistically for 12 to 24 h.
Traps were unbaited
and coated with a 50% dilution of Fluon[R] that previously had been shown to be as effective at catching A.
All nets deployed in the lower reach were unbaited
, while all nets deployed in the upper reaches were baited with AquaMax [TM] Grower 600 for carnivorous species (Purina Mills Inc., Brentwood, MO; Stone, 2005).
In the forest, a trap baited with CO2 gas (250 cc per min) caught more flies than a similar, unbaited
I also occasionally place an unbaited
camera near a heavy creek crossing or well-used funnel, but I stay away from any likely sanctuaries and bedding areas.
Bait method (i.e., baited trap, unbaited
trap) was dummy coded (i.e., the categorical variable bait method was converted to a continuous variable by assigning values of 0 for baited trap deployments and values of 1 for unbaited
trap deployments) and the continuous variable was included as a covariate in the models to control for its possible influence on values of MeanCount.
subfasciatus than unbaited
control traps (Nakashima et al., 1994).
A total of 10 unbaited
traps were distributed unsystematically in the "murundus" (Ponce & Nunes-da-Cunha, 1993; Por, 1995), termite earth mounds that are not submerged in the flood period in the "cambarazal".
We placed unbaited
traps at least 2 m from the nearest point where an animal could cross the field detection sensor at a height of 20-30 cm above ground.
(2011) demonstrated that unbaited
cameras along trails were a feasible alternative to using baited cameras and that baited cameras failed to provide sex ratio and recruitment estimates that matched estimates from randomly placed unbaited
The Lindgren, Intercept, and window traps were baited with ethanol, while the purple sticky traps were left unbaited
One day, I stared at their obvious trails through the grass and garden and wondered whether plain, unbaited
mousetraps would catch them.
