| In the temperate forests of Chile and Argentina the phytophagous moth Ormiscodes amphimone (F.) causes severe defoliation on the southern beech tree Nothofagus pumilio (Poepp. & Endl.) Krasser. The recent increase in defoliation frequency in some áreas appears to be influenced by a warmer climate. To evalúate the effects of temperature and the spatial heterogeneity of foliage quality on the performance and relative consumption rate of O. amphimone in northwestern Patagonia, Argentina we conducted a factorial experiment. Larval performance was measured as relative growth rate, developmental time, larval survival, and pupal weight. Larvae of O. amphimone were reared under two constant temperature regimes (15 °C and 20 °C) and fed with two N. pumilio... |
