abstract = {For many adult nectar-feeding parasitoids food and moisture
are essential for survival in the field. Early in the
season, when floral nectar is not yet available in cotton,
extrafloral nectar (EFN) is already present on young cotton
plants. 2 The parasitoid Microplitis croceipes (Cresson) can
use EFN cotton plants as an only food source. The longevity
and reproduction of EFN-fed female wasps was comparable to
wasps fed with honey and water provided on nectariless (NL)
cotton plants, and was significantly higher compared with
wasps kept on NL plants with no additional food source. 3
Wasps that were given preflight experiences on EFN cotton
plants choose EFN cotton over NL cotton plants in two choice
experiments in the flight tunnel. The parasitoids are more
willing to search on an EFN plant at their second and third
encounter with a plant previously visited, compared with an
NL cotton plant. 4 Wasps can locate EFN from short distances
by its odour alone, and find it almost as fast as honey, but
much faster than odourless sucrose, which is only found
randomly. Experience with EFN increased the retention
ability of parasitoids on a flower model.},
