Abstract EN
Talh trees (Acacia gerrardii Benth.) are acacias that are native to the arid and semiarid Africa and west Asia.
We investigated the flowering biology, pod set and flower visitors of Talh and discussed the role of these visitors in pollen transfer.
The Talh trees blossomed laterally on the nodes of one-year-old twigs.
Each node produced 21 flower buds seasonally.
Each flower bud opened to a flower head (FH) of 60 florets.
The bagged FHs podded significantly (p 6 0.05) less than did the unbagged FHs.
The FHs were visited by 31 insect species (25 genera, 16 families and 5 orders).
The major taxa were honeybees, megachilids, butterflies, ants, beetles and thrips.
Each of honeybees, megachilids and beetles showed a significant (p 6 0.05) hourly pattern, while each of butterflies, ants and thrips had no hourly pattern (p> 0.05).
Furthermore, some birds and mammals touched the Talh FHs.
Talh trees evolved a mass flowering behavior to face preand post-flowering obstacles.
Megachilids seemed to play the major effort of zoophily because of their relatively high numbers of individuals and species and their effective movement behavior on the FH surface.
Nevertheless, honeybees and other insects and vertebrate taxa also contributed to the pollen transfer.
These results greatly contribute to our understanding of the pollination ecology of acacias, especially Arabian acacias.
