Hundreds of insect species are nowadays reared under laboratory conditions. Rearing of insects always implicates the risk of diseases, among which microbial infections are the most frequent and difficult problems. Although there are effective prophylactic treatments, the side effects of applied antibiotics are not well understood. We examined the effect of prophylactic antibiotic treatment on the overwintering success of wood tiger moth (Parasemia plantaginis) larvae, and the postdiapause effect on their life-history traits. Four weeks before hibernation larvae were treated with a widely used antibiotic (fumagillin). We monitored moths’ survival and life-history traits during the following 10 mo, and compared them to those of untreated control larvae. Prophylactic antibiotic treatment had no effect on survival but we show effects on some life-history traits by decreasing the developmental time of treated larvae. However, we also revealed relevant negative effects, as antibiotic treated individuals show a decreased number of laid eggs and also furthermore a suppressed immunocompetence. These results implicate, that a prophylactic medication can also lead to negative effects on lifehistory traits and reproductive success, which should be seriously taken in consideration when applying a prophylactic treatment to laboratory reared insect populations. ...

Medicative diet : the importance of diet and prophylactic treatment on survival and immunity of polyphagous Arctia plantaginis (Arctiidae) larvae Dickel, Franziska (University of Jyväskylä, 2018)Diet is one of the major factors directly and indirectly influencing insect’s life history traits and risk of getting infected. Additionally the insect’s fitness is severely affected by the broad diversity of parasites ...
Evolutionary rescue at different rates of environmental change is affected by trade‐offs between short‐term performance and long‐term survival Liukkonen, Martta; Kronholm, Ilkka; Ketola, Tarmo (Wiley-Blackwell, 2021)As climate change accelerates and habitats free from anthropogenic impacts diminish, populations are forced to migrate or to adapt quickly. Evolutionary rescue (ER) is a phenomenon, in which a population is able to avoid ...
