Enumeration of pollinators and floral visitors of some common weeds with notes on pollen characteristics
2018
Barrion-Dupo, A.L.A.
Inflorescences of six common weeds each representing its plant family, namely: Amaranthus spinosus L. (Amaranthaceae), Tridax procumbens L. (Asteraceae), Coccinia grandis (L.) Voigt (Cucurbitaceae), Euphorbia hirta L. (Euphorbiaceae), Oxalis corniculata L. (Oxalidaceae), and Lantana camara L. (Verbenaceae), were sampled. Data on the morphology of these flowers were compiled and pollen grains were extracted through the Feagri and Iversen's Acetolysis Procedure. In addition, floral visitors and pollinators were identified. Arthropod visitors and pollinators of these common weeds were mostly managed pollinators like Apis mellifera L. and Tetragonula biroi (Friese). Meanwhile, pierid and hesperiid butterflies comprised the lepidopteran floral visitors. New host plant records for these butterflies are reported from among these weeds.
