摘要：

The flowers of Opuntia basilaris and O. littoralis in southern California are visited commonly by beetles (Carpophilus, Trichochrous) and bees (especially anthophorids, megachilids, and halictids), but are pollinated mainly by the bees. This agrees with observations presented in the previous papers in this series for other cactus species in Arizona and Texas. The available evidence indicates that the large, diurnal, cup-shaped flowers in cacti of the American Southwest are primarily bee-pollinated. Our earlier view that these Opuntia flowers are also pollinated to a significant extent by nitidulid and melyrid beetles must be modified now in the light of further evidence. Some pollination probably is carried out by small beetles, but it probably represents only a small proportion of the total pollination. © 1979 Springer-Verlag.
