Parasitic strategies based on behavioral manipulation of the arthropod host
Janovská, Kateřina ; Straka, Jakub (advisor) ; Votýpka, Jan (referee)
It is well known that parasites can alter the host's behaviour for their benefit or the benefit of their offspring. Arthropods often fall victim to these parasites. Although the parasites of Arthropods come from many different groups (e.g., helminths, insects, fungi, viruses, etc.), we can find some similarities in their strategies. The specific methods and processes of behavioural manipulation are unique to each parasite and depend on whether the arthropod is the parasite's final host or an intermediate host/vector. However, they often lead to the same goal, e.g., to be eaten by another host, to allow the parasite to reproduce or to protect the parasite's offspring. Whether these changes in the host's behaviour are a part of the parasite's life strategy or only a manifestation of an adaptive response of the host remains a question. This thesis discuss specific cases of behavioural manipulation in parasitized arthropods and the common motives parasites use in manipulation. Keywords: behaviour manipulation, Arthropods parasite, parasitoid, host's behaviour, host- parasite interaction, adaptive response
