[Syrphidae] Efficiency of trapping methods for flower flies

[christian thompson]

Sorry, but I am lazy today

Beyond Jennifer Owen's landmark study of the flower flies in her garden
(1991*) are there any other good long term studies that report the
efficiency of various trapping methods to sample the flower fly fauna?
As I remember it, Jennifer was able over the first 15 years to recover
about 70% of the fauna and able to get most of that in the first 3
years.

And are there any good studies on comparison between methods like pan
traps versus malaise traps.

THANKS

 
*And yes, I do remember that Francis published an up-date on Jennifer's
work.
