| Popis: | Environmental variation can have profound and direct effects on fitness, fecundity, and host symbiont interactions. Replication rates of microbes within arthropod hosts, for example, are correlated with incubation temperature but less is known about the influence of host-symbiont dynamics on environmental preference. Hence, we conducted thermal preference (Tp) assays and tested if infection status and genetic variation in endosymbiont bacteriumWolbachiaaffected temperature choice ofDrosophila melanogaster. We demonstrate that isogenic flies infected withWolbachiapreferred lower temperatures compared to uninfectedDrosophila. Moreover,Tpvaried with respect to three investigatedWolbachiavariants (wMel,wMelCS andwMelPop). While uninfected individuals preferred 24.4°C, we found significant shifts of - 1.2°C inwMel- and −4°C in flies infected either withwMelCS orwMelPop. We, therefore, postulate thatWolbachia-associatedTpvariation within a host species might represent a behavioral accommodation to host-symbiont interactions and trigger behavioral self-medication and bacterial titer regulation by the host. |
