Diet breadth modulates preference - performance relationships in a phytophagous insect community

Abstract In most phytophagous insects, larvae are less mobile than adults and their fitness depends on the plant chosen by their mother. To maximize fitness, adult preference and larval performance should thus be correlated. This correlation is not always apparent and seems to increase with the leve...
