Another "Mistake Jump" of Bee Collapse Colony Research?

A car driver hit another car and asked by a police.
"Why you don't hit the brake when you see another car in front of you?" ask the Policeman.
"I have read the traffic rules, there no order to brake in this circumstances."

Honey bees play a critical role in agriculture. The most important role honey bees play is actually not honey production, but pollination. The value of crops that require pollination by honey bees, in the United States alone, is estimated to be around $24 billion each year and commercial bee pollination was valued around $10 billion annually.

Honey bee colony losses are not uncommon, however, this sort of disappearance is unprecedented. This honey bee colony loss is due to uncharacteristic bee behavior: bees are failing to return to the hive. Research found no evidence to suggest that pesticides or bacterial infection are the primary cause of CCD (colony Collapse Disorder).

So, if the root cause is the navigation system, why we not focusing in the bee navigation first? If the anomaly of bee navigation revealed, we can understand weather the collapse is biologically or environmentally. Then, we can continue the research depend on the previous result.

But, as we have not reveal the process of collapse colony, scientists try to explain the collapse with DNA, Bacteria, Virus, pollution, etc. Most of their research result will fail to explain the process of collapse colony. Mostly, their truth is like the truth of the driver in the prologue of this article.

Another wasting time and money.
