Polymorphism of 10 Beauveria bassiana strains, isolated from Ixodes ricinus in Moldova, was evaluated using traditional (morphological and cultural properties) and molecular (RAPD patterns and ITS sequences) methods. The isolates differed greatly in morphological and cultural features, such as color, consistence, and growth rate. Four RAPD-PCR markers were used to ...

Female Ixodes ricinus (ticks) are able to consume several times as much as their own weight in food. The body volume increases without the animal moulting. Special structural and material characteristics of the cuticular exoskeleton render this phenomenon possible. Only the alloscutum, which has a very pronounced lamellar structure, extends. ...
