An instrument for measuring the resistance of the leaf and culm of forage and crop plants to cutting and chewing insects
Journal of Economic Entomology 61 (4), 1114-1115
Abstract: An instrument devised to test the resistance of growing plants to feeding by chewing insects and oviposition puncture, is described. Out of 18 spp. of grass tested, Agropyron trichophorum, A. dasystachyum and Stipa viridula were significantly tougher. Bioassay showed that 4th-instar hoppers of Melanoplus sanguinipes least preferred the latter two species as food plants and most preferred the former, indicating that factors other than leaf toughness are involved in host plant selection.
