The article is indeed weak in detail and appears as a PR piece.
It talks about a hybrid bee (Apis melifera) that has resistance to varroa mites. It does not explain how they achieve this resistance and just hints that maybe it is due to the longer legs of this hybrid. Or, they produce more propolis than other bees.
While the article is titled about colony collapse, it talks about a hybrid that is somehow less susceptible to mites. Does not mention neonicotinoids, which mainly cause the colony collapse.
