Kamikaze Bees - Why Does The Swarm Commit Suicide?

Dah beberapa minggu sekumpulan lebah (5-10 ekor) datang masuk rumah (masuk dapur to be exact), pusing-pusing kat lampu beberapa kali, pestu jatuh mati. Tiap-tiap hari saya kena sapu, kalo tidak memang berterabur la kat lantai. Kalo tak sapu, tak pasal-pasal terpijak plak nanti. :P

Ni hasil sapuan 6 May 2014, bilangan paling banyak yang bunuh diri setakat ini - 11 ekor. Abaikan helaian rambut yang interframe. :P

Persoalannya kat sini, kenapa lebah-lebah ni bunuh diri?

Saya cuba google, dan ini jawapan yang paling logik saya dapat.

"Bees commit suicide - but it is more a self euthenasia thing. If they know they are injured or won't make it back to the hive they will sting themselves." ~ answered by Liam, Eltham

"The stinging honey bee worker commits suicide when her sting is torn out, but this saves her kin. She is not ‘making an escape from outrageous fortune’ (like Shakespeare’s Hamlet), but making the best of it – not fearful of what dreams may come, but hopeful for what genes may come. However socially constrained her life may have been, her last action makes her own clear statement: long live the kin!" ~ by beelogics.com

Colony Collapse Disorder (CCD) is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear. This behavior is a form of extreme altruism in honey bees that involves a worker committing altruistic suicide if they become cognizant of some sort of decrease in their own health and vitality, whether by fungal infection, CO2 exposure, or hydroxyurea consumption. In order to reduce the chance of transmitting a possible pathogen to their colony, bees (as well as other social insects such as ants) will abandon their normal social function and remove themselves from the colony. The paper was able to control for the potential alternative explanations of the experimental treatments of host manipulation, disorientation, and lack of mental function (possible side-effects of the various treatments) and support their hypothesis that this behavior was actually adaptive! ~ by abbotlab.wordpress.com
