An interaction between a specialized seed predator moth and its dioecious host plant shifting from parasitism to mutualism

Article Abstract:

A relationship between a seed predator, the geometrid moth Perizoma affinitatum, and the dioecious plant Silene dioica, is described to study the early stages of evolution towards mutualism. A high pollinating ability and limited seed consumption by the predator was found and discussed in relation to fitness models of P. affinitatum and S. dioica.

Effects of nutrient availability on biomass allocation as well as constitutive and rapid induced herbivore resistance in poplar

Article Abstract:

The effects of nutrient availability on expression of constitutive resistance of poplar to gypsy moth (Lymantria dispar) and whitemarked tussock moth (Orgyia leucostigma) are examined. The effects of nutrient availability on expression of rapid induced resistance (RIR) are also described.

Body size distributions of large Costa Rican dry forest moths and the underlying relationship between plant and pollinator morphology

Article Abstract:

The species' body size distributions in two assemblages of large Costa Rican moths are examined. It is concluded that neither adult Sphingidae or Saturniidae exhibit the classic log right-skewed pattern.
