Jatropha curcas
L. is a tropical tree belonging to the Euphorbiaceae family with oil-rich seeds that are currently
used as a source of biodisel. A better knowledge of the reproductive ecology is imperative for yield optimisation
and invasiveness risk assessment. Insight in the diversity and movement of potential pollinators, forms an
important aspect of the needed knowledge. In this paper, we report on
J. curcas flower visitors observed in two
Southern African countries, Zambia and Malawi. A total of 41 insects and 2 Arachnida in Zambia and 29 insect
species in Malawi visited
J. curcas flowers. Diptera and Hymenoptera were the largest groups. The most
abundant insect visitors were
Apis mellifera
and
Chrysomya chloropyga
.
Apis mellifera visited more inflorescences
within short periods than
C. chloropyga, and showed a frequent appearance in both sites. Therefore,
Apis
mellifera seems to be more important in the pollination process of
J. curcas in the Southern African region.
