Abstract: Impacts of climate change may affect population performance directly or indirectly through mediated effects on their mutualists. Recently, my colleagues and I showed that the stink bugs species Nezara viridula, Acrosternum hilare, Murgantia histrionica harbor a dominant caecum-associated symbiont. We detected the symbionts presence in the gastric caecum through PCR (Polymerase chain reaction) by using specific primers and monitored the demographic parameters of the insects rearing them at 25 and 30°C. High temperature (30ºC) eliminated the caeca-associated symbionts of A. hilare and M. histrionica. Mortality of A. hilare was substantially higher at 30°C in the first generation, however M. histrionica only started to show higher mortality at 30°C during second generation. Here I present the data of Prado et al. (2010) which showed that host fitness was potentially mediated by symbiont loss at 30°C, and that climate changes can have influence on the host's development, ecology, and geographic localization. |
