AbstractThe effects of host and non-host plant odours on the foraging responses of the banana weevil, Cosmopolites sordidus (Germar), were investigated in the laboratory through arena and olfactometer bioassays. Contrary to previous reports that banana rhizome and pseudostem were the most attractive parts to the weevil, dead leaves were most preferred. Comparison of dead banana leaves with dead leaves of other plants showed that attractant odours were present in yam, cocoyam and dead grasses but absent in cocoa and soybean leaves. Complete leaf senescence while the leaf was attached to the mother plant proved necessary for the development of the dead-leaf-based odours but the involvement of microbial organisms could not be demonstrated. It is possible that dead-leaf-based attractants could be used in combination with microbials such as entomogenous fungi and nematodes in integrated management of C. sordidus.

Egg Parasitoids

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).
