“…Although resin is essential to many aspects of stingless bee nest construction and defense, little is known about how stingless bees obtain this vital resource. Some information on resin foraging can be gleaned from studies on general foraging behavior [78][79][80][81], but there are few studies that examine resin foraging in stingless bees specifically (except see [24,62,65]).…”

Stingless bees (Meliponini) are highly social bees that are native to tropical and sub-tropical ecosystems. Resin use is vital to many aspects of stingless bee colony function. Stingless bees use resin to build essential nest structures, repel predators, and kill would-be invaders. Furthermore, resin-derived compounds have been found to enrich the cuticular chemical profiles of many stingless bee species, and resin may play an important role in shaping the microbial communities associated with stingless bees and their nests. Despite its importance for colony function, previous reviews of resin use by stingless bees are lacking. This topic grows increasingly urgent as changes in beekeeping and land use practices occur, potentially diminishing stingless bees’ ability to incorporate resin into the nest environment. In this article, we review existing literature on resin use by stingless bees and discuss potential areas of future research.

“…The density of bees in flowers was influenced by seasons, marked by the semiarid climate characteristic of the region, assuming an effect of temperature, sunshine, and precipitation on the foraging of individuals. The influence of climatic factors on the flow of external activity of bees has been addressed in different species, and there is evidence of positive modulation in foraging intensity with temperature and light intensity (Alves et al 2015; De Brui- jn and Sommeijer 1997; Palma et al 2008;Silva and Gimenes 2014). Under the conditions of this study, there was bee activity in the different seasons, but with a significant reduction in the colder seasons.…”

Background: Pollination is an ecosystem service of utmost importance for agriculture. In this context, the study aimed to evaluate the pollination service of naturally occurring bees and after densification with colonies of stingless bees (Nannotrigona testceicornis and Tetragonisca angustula) in commercial strawberry plantation. The study was carried out in the four seasons of the year and under two experimental conditions: natural pollination (NP) and pollination under bee densification. The supply of flowers and bee density were estimated. For bee densification, four boxes of colonies of Iraí bees and four of Jataí bees were placed near the strawberry plantation. Five treatments were established for each condition, considering NP and pollination with bee densification on different days from flower anthesis, ranging from the 1st to the 5th day. Fruits were harvested, quantified, and submitted to evaluations to determine biometry, degree of deformity, and percentage of fertilized achenes. Results: There was a higher density in summer compared to other seasons in both conditions evaluated. The weight was greater (20.19 g) when fruits were pollinated on the first day after floral anthesis under pollination conditions with bee densification. It was observed that free pollination provided fruits with greater a greater of deformation of flowers on the fourth and fifth day after anthesis. However, when bee density became higher, the greatest degree of deformity was observed only in fifth-day fruits. The densification with stingless bees provided a 50% increase in the number of bees present on strawberry plants in summer and also a 15% increase in fruit weight and the occurrence of a lower degree of fruit deformity. Conclusions: Density with stingless bees provided a 50% increase in the number of bees present on strawberry plant in the summer, with an improvement in fruit quality and aggregate commercial value, providing a 15% increase in fruit weight and a lower degree of deformity under the conditions of densification of Iraí (N. testceicornis) and Jataí (T. angustula) bees. Under the evaluated conditions, the introduction of stingless bee boxes in the summer is recommended.

Data on temperature and relative humidity were collected by using a mobile digital thermo-hygrometer and light intensity was recorded by using a portable lux meter (HI 97 500; digital light-gauge range: 0.1-199.9 Klux) at a distance of about 1,5 m from the ground [19].…”

Insect pollinators is one of the important factors in the cross-pollination of coffee flowers, which affects the coffee fruit set. However, there is still a limited understanding of how shade trees in the coffee ecosystem affect insect pollinators. The purpose of this study was to obtain information on the effect of climate variations at different shading levels in the coffee ecosystem to the population and diurnal activity of insect pollinators. The shade levels are categorized in three ways, namely high shade, low shade, and open shade. The observation was conducted at the time when the flower blooms with sample units a flower in two coffee branches. Insect pollinators that show feeding behavior in coffee flowers were recorded in the morning, while the diurnal activity of each species pollinator was observed in the morning, midday, and afternoon. The study showed five species of insects belonging to three families and two orders, Hymenoptera and Lepidoptera that showed feeding behavior on coffee flowers. Apis cerana and Apis mellifera were the dominant pollinators of coffee flowers. The difference in shade levels did not affect pollinator species to visit coffee flowers, but their population tends to decrease in the open shade, except Apis cerana. The peak of diurnal activity of insect pollinator recorded in the morning decreased at midday and showed an increase slightly in the afternoon until the end of the diurnal activity. An increase of temperature may significantly decrease the number of pollinators that visit coffee flowers, while humidity and light intensity showed no significant effect.
