Responses of Invertebrate Herbivores to Stinging Trichomes of Urtica dioica and Laportea canadensis

摘要: We investigated whether stinging trichomes of two plant species, Urtica dioica and Laportea canadensis, are effective defenses against four species invertebrate herbivores (Vanessa atalanta, Popillia japonica, Chortophaga viridifasciata Anguispira alternata). Feeding was compared on leaf pieces contrasting trichome density, in petri-dish feeding trials. In addition, a test snail movement over hairy shaved L. canadensis stems carried out. no case there significant evidence that deter or interfere with by these herbivores. Factors body size behavior allow them to feed little interference from nettle stings. Stinging known be mammalian herbivores, well-suited deterrence large grazers. therefore hypothesize has evolved as defense herbivory.
