What Are Social Insects Telling Us About Aging?, Joel D. Parker
Joel D Parker
Abstract: Research on aging in social insects has progressed much more than has been generally acknowledged. Here I review what I think are the four greatest contributions of social insect work to the field of aging research with the hope of highlighting the truly exciting discoveries being made. These include the reversal of the fecundity / lifespan and size / lifespan trade-offs due to the evolution of sociality, that social environment can reverse the effects of aging, the contribution of social insect work to the overturning of the free radical theory of aging, and the discovery of vitellogenin as an …

A study was conducted to investigate the effects of sucrose and kinetin on the post harvest quality and vase life of Bougainvillea bracts at different storage temperature. Bougainvillea bracts and flower (Bougainvillea glabra) of the same age and size were used in the experiments. Fresh bracts were continuously treated with 200 mg/l sucrose, 200mg/l kinetin and control (water) at 10 degrees C, 20 degrees C and 28 +/- 1 degrees C. It was observed that sucrose treated bracts exhibited the longest vase life compared to the control and kinetin treatments at different temperatures. The higher temperature has promoted water uptake, …
