List readers who want to follow up on Allen Dick's recent posting as to the
use of grease in the control of tracheal mites may want to look at:
Diana Sammataro, Susan Cobey, Brian H. Smith and Glen R. Needham,
"Controlling Tracheal Mites..In Honey Bees..With Vegetable Oil," _J of
Economic Entomology_, 87, (4): 910-16 (1994).
The abstract reads in part:
"Field experiments ...between 1991 and 1993 demonstrated that treating
colonies of honey bees...continuously with vegetable oil depressed
populations of tracheal mites....Oil patties were made from a combination of
solid vegetable oil (shortening) and white sugar, with or without the
addition of [Terramycin]."
References cited in this article include at least two other directly
relevant papers.

I recently read that DR Deleplane co-authored a paper concerning the use of
grease patties for "T" mite control in summer. He recommends a mixing 2
parts Crisco or other vegetable shortening to 1 part powdered sugar. Press
into patties between waxed paper and insert over the brood nest. Make sure
that the shortening is 100% vegatable oil and not animal fat. Measurements
are by weight. Granulated sugar can also be used if you prefer.
I will try to get a copy of the article and post it to the list. Also if
possible I will try to get a cop of the paper at the seminar next week and
post it to the list
