  • insect invasions, lessons from biological control of weeds;
  • theory of invasions, for spatial and temporal fluctuations of arthropods;
  • population establishment, a stochastic process;
  • stochasticity, Allee effects, and number of individuals released;
  • Allee effect, population growth rate reduction at low densities;
  • biotic interactions affecting insect dynamics;
  • competitive interactions, one control organism preying on another;
  • top-down effects of natural enemies on herbivore demography;
  • herbivores and resources, mechanism and feed back to plants;
  • biological control systems, invasion, spread and dispersal
