Formatted abstract
A pollination and seed production study of Mikania micrantha Kunth was undertaken in Viti Levu, Fiji to determine the impact of rainfall upon the reproductive potential of this weed. Twenty-one insect taxa belonging to 17 families visited the field sites during the three days of study. Out of the total individual visitors (n = 1255), the order Diptera was the most abundant (38%), followed by Hymenoptera (34%), Lepidoptera (27%) and Coleoptera (0.5%). In the Hymenoptera, the honeybee (Apis mellifera L.) was the most abundant visitor (58% of all Hymenoptera visits) and was observed to have the longest foraging time than any other floral visitors. Wet weather reduced the number of floral visits by all taxonomic groups and thus influenced the production of filled seed. There was a greater proportion of filled seed produced by mikania plants per m2 in the moderate rainfall region (61%) than in high rainfall region (51%). There was an average of about 94,500 viable seed m-2 produced in both regions. Rainfall has an important role to play in the filling of seed of mikania but seems to have no effect upon overall seed production.
