If you're referring to the blank entries in the row next to elemol, that is most likely because it was not evaluated for anything other than repellency. If you're referring to an absence of more detailed experimental procedures, that is because the table is a summary of a summary of the primary literature. Apologies if I am telling you something that you already know.

The original research (primary literature) on elemol that is referenced in the table was contained in a 1990 dissertation by B. Kraus : Untersuchungen zur olfaktorischen Orientierung von Varroa jacobsoni Oud. und deren Störung durch ätherische Öle, Dissertation, Goethe-Universität, Frankfurt, Fachbereich Biologie, 1990. (I think this translates as "Studies on the olfactory system of Varroa jacobsoni (Oud.) and its interference by essential oils" Goethe University, Frankfurt, Department of Biology). I have not looked for this dissertation. Someone at WVU likely has a copy, though. Here is the abstract of the dissertation:
"In laboratory tests, 21 of 32 oils tested were repellent to mites; citronella oil (C) had the greatest effect, followed by lavender oil. Only oil of cloves was attractive to mites, and one of its constituents, eugenol, was also attractive. The lowest effective concentration for 5 oils tested was 0.1% (in 10 g wax); this was not toxic to bees. The repellent effect of C to mites was reduced by marjoram oil or cinnamon oil. When oils were incorporated in the midrib of comb in mating hives, bees were unaffected. With marjoram oil (M), the number of mites in brood cells was reduced by 45%, and with oil of cloves by 31%. M also disturbed the orientation of mites. In tests of the effect on mites of honey bee alarm pheromones, the sting apparatus and individual constituents, especially 1-octanol, were repellent. Mites were hardly attracted by bees 5 mm away, but they could distinguish between nurse bees and pollen foragers. Adult bees seemed to be as attractive as larvae."
Note: Although the dissertation refers to V. jacobsoni, it is likely that the results also apply to V. destructor http://www.ncbi.nlm.nih.gov/pubmed/11108385
