Evidence for kairomones used by the egg parasitoid Anaphes victus (Hymenoptera: Mymaridae) when searching for its host

Because the detectability of host eggs is low, egg parasitoids rely on infochemicals other than those from the host egg itself, such as host plant synomones (Nordlund 1994; Meiners et al. 2000) and adult host kairomones (Nordlund et al. 1983; Nordlund 1994; Colazza et al. 1999; Meiners et al. 2000). Egg kairomones are used only in the final stages of host selection (Kainoh et al. 1982; Strand and Vinson 1982, 1983; Nordlund et al. 1987; Meiners et al. 2000; Takasu and Nordlund 2001).
