Honey bees – with a tiny brain the size of a sesame seed – can solve amazingly difficult problems (esp navigational challenges). Here is some research that suggests when young bees are stressed and sent out to labor too early – bee colonies collapse.
With their greater understanding of the collapse process, the authors are now exploring possible strategies to improve colony resilience including rescue packages for sick colonies, and new sensors to detect colonies at risk of failure.

Honey bee colony death rates are unsustainably high. While many stressors have been identified that contribute to this problem, we do not know why colonies transition so rapidly from a state of apparent health to failure. It is well known that individual bees react to nutritional and pathogen stresses by foraging precociously: our study explains how colony failure arises from the social responses of individual bees to stress. We used radio tracking to monitor performance of bees and found that workers who begin foraging prematurely perform very poorly. This compounds the stresses on the colony and accelerates failure. We suggest how colonies at risk can be identified early, and the most effective interventions to prevent failure.

Colony Collapes Disorder
Colony collapse disorder causes significant economic losses because many agricultural crops (although no staple foods) worldwide are pollinated by western honey bees. According to the Agriculture and Consumer Protection Department of the Food and Agriculture Organization of the United Nations, the worth of global crops with honeybee’s pollination was estimated to be close to $200 billion in 2005. Shortages of bees in the US have increased the cost to farmers renting them for pollination services by up to 20%. (ref Wikipedia
Arguably the insect suffering involved here is in and of it self bad enough – though people listen when they hear about Colony Collapse Disorder – or how the loss of bee colonies effects peoples food supply lines (leading to more suffering). I’d be interested to know what Brian Tomasik and David Pearce thinks about this.
