Abstract

In laboratory experiments we investigated hunting behavior towards insects in Phodopus sungorus (Pallas 1773), P. campbelli (Thomas 1905), Allocricetulus eversmanni (Brandt 1859) and A. curtatus (Allen 1925). In these species purposeful inter-relations with insects in the "predator-prey" manner have been revealed and described in details. In all species investigated the patterns of hunting are comparable with those of specialised predator hamsters. In a quarter of all cases hamsters start attacks from seizure the prey with paws, which is considering more evolutionary progressive than capturing with teeth. The dwarf hamster P. sungorus demonstrates the most simple pattern of hunting, whereas in other species some features of specialization have been revealed, such as different forms of manipulation activity. A. curtatus displays the most swift and effective attacks towards insects. We speculate that the obligatory innate patterns of hunting in both Allocricetulus species are connected with more specialised predatory behavior of members of this more evolutionary young group as compared to members of the genus Phodopus, with their optional hunting patterns which need experience to be completed.
