Evolution of host choice in parasitoids marking pheromones superparasitism and patch leaving

The parasitoids are a rich source of ideas in ecology and evolutionary biology; everyone should be excited by them! The examples considered in the text are literally only the tip of the iceberg. Some of my other favorite topics include the evolution of pheromones used to mark hosts after oviposition (Roitberg et a/. 1984, Roitberg and Prokopy 1987, Roitberg and Lalonde 1991); whether parasitoids feed on a host (to make more eggs) or lay an egg in it (de Bach 1943, Edwards 1954, Bartlett 1964, Jervis and Kidd 1986, Walter 1988, Rosenheim and Rosen 1992, Heimpel et a/. 1994, Heimpel and Rosenheim 1995, Heimpel and Collier 1996, McGregor 1997, Giron et a/. 2002); whether parasitoids (or tephritid fruit flies) lay an egg in a host that has already been attacked (which they can tell because of the marking pheromone, for example) or, rather, ignore superparasitism of such hosts (Pritchard 1969, Hubbard and Cook 1978, Hubbard et a/. 1987, van Alphen et a/. 1987, van Alphen and Visser 1990, van Randen and Roitberg 1996); whether parasitoids will search for oviposition sites or food sites (to find both carbohydrate, to run the operation, and protein, to make more eggs if they are synovigenic) (Lewis and Takasu 1990, Waeckers 1994, Heimpel et a/. 1997, Olson et a/. 2000); what happens to parasitoids in the field (Janssen et a/. 1988, Janssen 1989); information as a state variable (Roitberg 1990, Haccou et a/. 1991, Hemerik et a/. 2002); the effects of intraspecific competition between ovipositing females, making the oviposition behavior a dynamic game (Visser and Rosenheim 1998); the effects of hyperparasitism (parasitoids of parasitoids) on oviposition behavior (Mackauer and Voekl 1993); the role of sex ratio in population dynamics (Hassell et a/. 1983) and behavior (Olson and Andow 1997); and patch-leaving behavior (Hemerik et a/. 1993, Rosenheim and Mangel 1994, Vos et a/. 1998, Wajnberg et a/. 2000, van Alphen et a/. 2003). Stochastic dynamic programming provides a natural means for making predictions about the interactions of age, egg complement and behavior. These predictions are also imminently testable (Cook and Hubbard 1977, Hubbard and Cook 1978, Marris et a/. 1986, Rosenheim and Rosen 1992, Fletcher et a/. 1994, Heimpel et a/. 1996, Rosenheim and Heimpel 1998, Vos and Hemerik 2003).
