5 flies per trap
per day before the period of this study (MARNDR 2014).
At each site, transects of 25 groups of three traps
(one clean, one dirty, and one experimental) were established for each trap
session, lasting three days (two nights; n = 150 trap
When saturation occurs, the number of insects in a trap
does not accurately represent the number of entries into the trap
, resulting in an underestimate of the population.
Now for the technical part--putting a trap
in the ground in such a way that it convinces an animal to step on the small trigger pan.
Key words: Honeybee, Apis mellifera, Pollen, pollen trap
, honey yield, Sarsoon.
RSPB covert surveillance cameras monitored the trap
belonging to a shoot in south west Northumberland and found the trap
operator had failed to attend the trap
at any point during the filming.
Pressure surges due to sudden steam valve openings and improper piping or trap
misapplication, which in addition to malfunction can result in water hammer, are some of the main reasons for failure resulting in either it leaking or the trap
However, because our experimental design differed in offering a choice between two treatments at the same location and a decontaminated trap
and a new trap
free of the odor of disinfectant or previously captured animals, we expected that our experimental design would best be able to illuminate any difference in preference and would demonstrate whether small mammals did choose disinfectant-free traps
must also bear a metal tag with the owner's name, town and registration number, which is assigned to a trapper for life.
Don DeMaria, a decorated veteran of the fish trap
battles, compared replacing longlines with fish traps
to "trying to cure small pox with anthrax.
Whether the failure is caused by a crushed ball-float or a broken linkage, a closed trap
can fill with condensate and eventually flood a portion of the steam system.
The catches of deliberately lost traps
were monitored and estimates of the number of trap
losses and causes of trap
losses were obtained through surveys of commercial fishermen.
Using a similar technique to sample several habitats over time, Duffey (1956) applied a tacky adhesive to the tops of canes to trap
Overall mean capture rates (total captures/100 adjusted trap
nights) by habitat were greater (P [less than or equal to] 0.
ABSTRACT: We sampled the small mammal community inhabiting semi-deciduous forest fragments in Mato Grosso, Brazil, using 4 different types of traps
, Tomahawk, Sherman, snap, and pitfall, in order to evaluate the efficiency of different trap
types in sampling efforts.
