We manipulated field densities of the leaf-mining insect Cameraria sp. nov. (Lepidop- tera: Gracillariidae) by caging them on branches of Quercus emoryi in central Arizona to test for intraspecific competition. High density cages (n = 7 replicates) had mean larval densities about 3 times those of low-density cages (n = 3 replicates). Our results demonstrate intraspecific competition in the form of density-dependent larval mortality. While mortality for leaf miners co-occurring on leaves was… CONTINUE READING
