“…Stingless bee responses to insecticides broadly vary, with evidence of avoidance or repellence [32,33,91,92], exclusion of foragers exposed to insecticides [93], not avoiding individuals from their colony treated with insecticide [94] and not rejecting resources containing insecticides [95]. Demonstrations of stingless bee responses to imidacloprid are limited, and we are only aware of two other studies that tested a response of a stingless bee to imidacloprid.…”

“…We then considered basing concentrations on known toxicities for the species; however, at the time of the experiments there were no published toxicities for any Tetragonula species for either insecticide. Finally, we decided to use studies of other bee species and scaled concentrations to body size [23,33,75] (electronic supplementary material, appendix 1). We chose oral exposure over contact exposure because oral exposure is the most likely route of exposure for bees [76].…”

“…The authors attribute their results to bees exposed to LC 10 attempting to consume as little sugar as possible as a behavioural defence mechanism to avoid imidacloprid intoxication, whereas bees exposed to LC 20 may have experienced physiological stress, and sucrose consumption may have been necessary for them to meet energy requirements for metabolic pathways and detoxifying capabilities [32]. In contrast , the stingless bee Tetragonula laeviceps chose honey over both honey containing the insecticides alpha-cypermethrin and spinetoram and the insecticides alone in a Y-tube olfactometer dual choice aroma assay [33]. Given the equivocal results and paucity of studies, further research into insecticide preference/avoidance in stingless bees in particular is warranted.…”

Insecticides and climate change are among the multiple stressors that bees face, but little is known about their synergistic effects, especially for non- Apis bee species. In laboratory experiments, we tested whether the stingless bee Tetragonula hockingsi avoids insecticide in sucrose solutions and how T. hockingsi responds to insecticide and heat stress combined. We found that T. hockingsi neither preferred nor avoided sucrose solutions with either low (2.5 × 10 −4 ng µl −1 imidacloprid or 1.0 × 10 −4 ng µl −1 fipronil) or high (2.5 × 10 −3 ng µl −1 imidacloprid or 1.0 × 10 −3 ng µl −1 fipronil) insecticide concentrations when offered alongside sucrose without insecticide. In our combined stress experiment, the smallest dose of imidacloprid (7.5 × 10 −4 ng) did not significantly affect thermal tolerance (CT max ). However, CT max significantly reduced by 0.8°C (±0.16 SE) and by 0.5°C (±0.16 SE) when bees were fed as little as 7.5 × 10 −3 ng of imidacloprid or 3.0 × 10 −4 ng of fipronil, respectively, and as much as 1.5°C (±0.16 SE) and 1.2°C (±0.16 SE) when bees were fed 7.5 × 10 −2 ng of imidacloprid or 3.0 × 10 −2 ng of fipronil, respectively. Predictions of temperature increase, and increased insecticide use in the tropics suggest that T. hockingsi will be at increased risk of the effects of both stressors in the future.

“…The average bee yield depends on the harvest and ranges from 10 to 20 kg of honey per year. The average Pole consumes from 0.3 to 0.4 kg of honey per year and to produce 1 kg of honey, bees must visit 5.7 million flowers (Mubin et al, 2022). Usually, one bee can visit from 50 to 1000 flowers in 1 year (Sultanova et al, 2019).…”

One of the oldest examples of the existence of beekeeping is the murals from the Araña Cave in Spain, which show people collecting honey from the nest of untamed bees. In ancient times, honey was used as a medicine and also to embalm corpses. During Greek feasts, it was an indispensable part of the menu. However, the greatest boom in beekeeping took place in ancient Rome, where hives made of straw and clay were found, dating back to 900 B.C. (Kritsky, 2017). The Egyptians placed a vessel filled with a "golden drink" in the tombs of the pharaohs, which showed that it was indeed considered something special. In the beginning, people discovered that honey collected by bees can be found in the hollows of trees. They climbed these trees, taking the honey from the bees-the result of their hard work. Then, they started to breed bees, building their nests in the hollows of old trees, the so-called beehives. Shortly thereafter, they noticed that you can only relocate the part of the tree to the field where the hollow is located, and then you will not have to climb to ensure you have constant access to this valuable product. Over time, people, thinking

Pesticides are chemicals or biological agents that farmers commonly use to control pests. Consequently, pesticides may contaminate agricultural products after application and also contaminate other commodities because of their high persistence. This research determined the pesticide contamination of two active ingredients, imidacloprid, and deltamethrin, in honey obtained from four beekeeping in Java. The honey samples of as much as 250g were collected from beekeeping of honeybee (Apis mellifera) in Blora-Central Java and Subang-West Java, also stingless bee (Tetragonula laeviceps) in Sumedang and Banten, West Java. Residue analysis was performed using the LC-MS/MS method in Saraswanti Indo Genetech, Bogor. The beekeeping location was around 500 to 1000 meters from cultivation plants, such as chili, shallot, and rice. Based on residue analysis results, the active ingredient was undetected, or the content of the detected active ingredient was below the limit of detection/LOD (<0.001 mg/kg of imidacloprid; <0.0039 mg/kg of deltamethrin). In addition, the LOD that can be detected was also underneath the maximum residue limit/MRL (0.05 mg/kg of imidacloprid; 0.03 mg/kg of deltamethrin). Therefore, honey from beekeeping was still secure for consumption. Even though all beekeeping locations were close to crops, the bees did not carry contaminated nectar from crops.
