<p align="justify"> Tetragonula laeviceps is a potential insect as pollinator agent of green bean and cucumber intercropping. The study was conducted on one planting season from January to March 2018, at Margabakti Village, Sukawangi, Sumedang. The observed harvest parameters include diameter, length, and weight of fruit. T. laeviceps taked 46 ± 22 seconds/flower to visit the green bean flowers and 8 seconds/flower to visit the cucumber flowers. The foraging speed of T. laeviceps was 1.15 flowers/minute on green bean flowers bunga buncis, and 2 flowers/minute on cucumber flowers. On observation of open pollination found species of dominant bee Apis cerana. Although open pollination resulted in higher efficiency in green beans (76%) and cucumber (71%), T. laeviceps bees can also help increase the efficiency of green bean pollination up to 54%. Visibility activity and pollination efficiency of T. laeviceps resulted in significant differences in the length of beans (16.74±1.16 cm), weight of beans (8.19 ± 1.76 cm), and cucumber length (12.3 ± 1.73 cm), in the other side of open pollination result are length of beans (15,34±1,31 cm), weight of beans (6,45±0,95 g), and cucumber length (10,86±1,1 cm). Then, it can be concluded that T. laeviceps can be used as an additional and potential pollinators on the cultivation of green bean and cucumber intercropping. <p align="justify">
