“…Environmental conditions affected thermoregulation of bees ( Sakagami et al 1983 ). The activities of T. laeviceps on the strawberry flower of this study (2.73 flowers/3 min) was lower than in strawberry (3.4 flowers/min) ( Harahap 2013 ) and 4.4 flowers/min on teak in Thailand ( Tangmitcharoen et al 2006 ). The peak activity of T. laeviceps in the current study (10.00 a.m. to 02.00 p.m.) was similar reported in North Vietnam ( Chinh et al 2005 ).…”

Stingless bees (Apidae: Meliponini) are distributed in tropical and subtropical areas in the world. Stingless bees are potential pollinator to increase yield of various crops species. We measured the pollination effectiveness of stingless bees, i.e., Tetragonula laeviceps in strawberry (Fragaria x annanassa) and Heterotrigona itama in melon (Cucumis melo) in the greenhouse. Pollination effectiveness of stingless bees were measured based on their visiting activities, i.e., foraging rate and flower handling time using focal sampling method. Measurements of fruit set consist of the number of fruits per plant, the number of normal and abnormal fruits, and the size and weight of fruits. Results showed that visiting activity of T. laeviceps in strawberry flowers ranged 2.33–2.73 flowers/3 min, while H. itama in melon flowers ranged 1.77–7.12 flower/3 min. Peak activities of H. itama in melon (7.12 flowers/3 min) occurred at 09.00 a.m.–10.00 a.m., while T. laeviceps in strawberry (2.73 flowers/3 min) occurred at 11.00 a.m.–12.00 a.m. Pollination by T. laeviceps increased 78.9% of fruit formation and reduced 16.7% of abnormal fruits of strawberry. In melon, ratio between female and male flowers was 0.03. The number of fruits produced in melon with T. itama (6.1 fruits/plant) was higher than in open field (2.6 fruits/plant) and control plants (no pollination) (0.2 fruits/plant). Pollination by H. itama increased fruit formation of melon.

“…flowers might allows the flowervisiting insects to land on the flowers, collecting the nectar at the base of the petals without contacting the anthers and stigma (illegitimate visits). This behaviour was reported for the small bodies' bee, as compared to their large size counterparts (Tangmitcharoen et al, 2006). The difference in time spent between the flowervisiting insects could be due to the depleted pollen grains in the already exploited flowers (Silva et al, 2013).…”

Many ornamental plants are aseasonal, providing continuous food supply which leads to survival of many flower-visiting insects. Although the flower-visiting insects are always perceived as pollinators, not all visitation actually resulted in pollination of the flowers. Thus, this study aimed to identify the flower-visiting insects of a common ornamental plant, Rosa spp., and to determine their potential role as pollinators from their foraging behaviour at the flowers. Data collection was conducted in Jasin, Melaka, in 2021. A camera was set up approximately 0.5 meter from the full bloom flower, throughout its anthesis period. From the video footage, the parameters recorded were visitation frequency, visitation type (legitimate and illegitimate visitation) and the time spent at the flower. As a result, 253 visitations were recorded by six insect taxa; four from the order Hymenoptera, and one each from the order Lepidoptera and Diptera. A hymenopteran bee, Halictidae sp. was found to show the highest visitation frequency. Only three species; Halictidae sp., Heterotrigona itama and Amegilla sp. showed legitimate visits. For the time spent (mean ± SE), Halictidae sp. (30.08 ± 4.87 minute) recorded significantly longer time as compared to other visitors (H = 13.78, df = 4, p < 0.01). Based on the visitation rate, time spent and visitation type, Halictidae sp. showed the highest potential as pollinator for Rosa spp., followed by H. itama and Amegilla sp. It is important to understand the contributions of the ornamental plants such as Rosa spp. as food source to these insects for conservation of these pollinating agents. Not only these flowers help in the survival of pollinating agents throughout the years, these pollinating agents also contribute to the survival of the flowering plants by facilitating the pollination process of the flowers they visited.

“…Bertholletia excelsa é uma espécie de planta com sistema reprodutivo auto-incompatível (Maués 2002), sendo, portanto, efi cientemente polinizada somente se seus polinizadores visitarem outros indivíduos na população (Goulson 1999, Singer & Koehler 2003, Richardison 2004, Tangmitcharoen et al 2006. Desse modo, é intrigante considerar que as abelhas sem ferrão, embora estejam afetando a atividade de forrageio dos polinizadores em questão, possam também, até certo ponto, contribuir para a polinização cruzada da castanheira.…”

-This paper presents an analysis of the foraging behavior and interactions of Xylocopa frontalis Olivier (Apidae: Xylocopini) and Eulaema mocsaryi (Friese) (Apidae: Euglossini) in the presence of stingless bees (Apidae: Meliponini) in fl owers of Bertholletia excelsa, the Brazilian nut. The palynological load carried by both species was also examined. This study was conducted in the farm Aruanã, Itacoatiara/ Amazonas state, Brazil, during the fl owering peak of B. excelsa. The visitation by the main pollinators X. frontalis and E. mocsaryi were infl uenced by the presence and activities of stingless bees in the fl owers of B. excelsa. Meliponini bees did not have any effect on the visits and collection of fl oral resources by X. frontalis, while negatively affecting the number of visits by E. mocsaryi. The stingless bees presented a variety of strategies to get access to pollen grains of B. excelsa, grouped into two categories: opportunism -Frieseomelitta trichocerata Moure, Tetragona goettei (Friese), and Tetragona kaieteurensis (Schwarz), and stealing -Trigona branneri Cockerell, Trigona fuscipennis Friese, and Trigona guianae Cockerell. The palynological analysis from X. frontalis showed that the bee collected pollen in a few species of plants, but mainly on B. excelsa. The pollen grains of B. excelsa were poorly represented in the pollen shipments of E. mocsaryi, due to its large trophic niche in the locality.KEY WORDS: Foraging strategy, interspecifi c relation, pollen stealing, Central Amazonia, Brazil Muitas espécies de plantas protegem suas recompensas fl orais em estruturas complexas que infl uenciam a tomada de decisão de um organismo em visitar ou não suas fl ores (Goulson 1999).
