Abstract

Tetragonula laeviceps was one of the most stingless bees that spread almost throughout Indonesia and produced honey and propolis. Nutmeg is one of the native plants of Indonesia, can be used by stingless bees. The aim of this study was to know the activity of Tetragonula laeviceps in monoculture and polyculture nutmeg plantation. The method used in this research is observation for outgoing and return activity, and t-test used to determine the activity. The result showed that the activity start at 6 am until 5 pm, and the peak activities are at 10 – 12 am. T-test shows the difference activities (P < 0,05) with the score 36,5 ± 20,9 bees/5 minutes at monoculture plantation and 24,88 ± 8,96 bees/ 5 minutes at polyculture plantation. The feed availability and the distance between the hive and plants are thought to influence the activities of bees in both location. External activities of Stingless bees are forage nectar, pollen and resin. Other activities are disposing of trash, driving out disabled bees from the hives, and protecting the hive from enemy attacks.

Abstract

Changes in foraging behavior of stingless bees are caused by their introduction to new environments with varying biotic and abiotic factors. These bees struggle to adapt due to the shift from their original range. Biotic factors, particularly food source abundance, are crucial for their survival. Limited resources and reduced competition can decrease hive pollen, affecting larval nutrition and adult morphological growth. This study examines the physical effects of introducing stingless bees from Sulawesi to Jawa, Indonesia, using PCA to analyze 35 morphological traits and a haemocytometer to calculate pollen load. Morphometry was performed on ten separate colonies and ten different individual worker bees. Research findings indicate that the most significant size changes were observed in the forewing and hindwing lengths of worker bees at the introduction site. The smaller body size in the new environment indicates less available food in the nest. The lower pollen collection in the new environment compared to their natural habitat confirms this. The decline in pollen load is attributed to biotic factors like competition and food availability. When stingless bees become non-native, they face competition with existing species, including natives. Abiotic factors do not significantly influence the reduction in worker bees' foraging activity in the new environment. Changes in environmental factors significantly influenced the morphometric measurements of worker bees, following their introduction to lowland areas.
