A Study of the Alydus tomentosus-Burkholderia Symbiont Interaction and Burkholderia Acquisition Open Access
Malik, Zayir Mohammed (2012)
Abstract
Alydus tomentosus, broad-headed bugs, house their symbiotic bacteria, Burkholderia, within their gut. While symbionts have been shown to confer positive benefits to the host in other broad-headed bug species, the effect of Burkholderia acquisition on A. tomentosus individuals remained unstudied. By monitoring the lifespans of multiple individuals, I show that A. tomentosus individuals that acquire Burkholderia survive at a higher rate than those that remain sterile. I also investigate the timing of bacterial acquisition. Through an experiment in which I expose A. tomentosus nymphs to Burkholderia during only one instar of their life, I demonstrate that A. tomentosus individuals are most likely to uptake their symbiont during their third instar. Finally, through a choice assay, I show that A. tomentosus do not actively seek out Burkholderia.
