Sometimes you need to refer the the help page for panel.<type of
plot>, in this case:
?panel.bwplot
... so the answer is now staring you in the face:
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos, pch="|")

Using the example in bwplot again, and a fair amount of fruitless
experimentation with the theory that one could do anything useful with
scales=list(at= list(<something>)), I finally ended up trying ,
labels=c( ) per Sarkar's Lattice book, producing this:
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos,
scales=list(x=list(
labels=c("A","","","D","","F","","")
)))
