Abstract

ORIG CZ

V originále

The dietary specialization in a woodlouse-eating spider Dysdera hungarica Kulczynski (Araneae: Dysderidae) is studied using two types of laboratory experiments. In the first experiment, the rate of development of spiderlings reared on one of three diets: pure woodlice [composed of two species Oniscus asellus Linnaeus and Armadillidium vulgare (Latreille)]; pure flies ( Drosophila melanogaster Meigen); and a mixed woodlouse-fly diet, is studied. Spiders develop significantly faster on the woodlice-containing diets (i.e. pure woodlice and mixed diet) than on the fly diet. In the second experiment, the prey-choice for two woodlice species ( O. asellus and A. vulgare ) and a fly ( D. melanogaster ) is investigated. Dysdera hungarica spiders capture significantly more often flies than woodlice. These contrasting results reveal the different value of developmental and behavioural experiments.
