“…Among the Asian honey bee taxa, A. cerana is a medium-sized honey bee (11.46± 0.091 to 12.74± 0.070 mm (Baskaran and Thiyagesan, 2013), smaller than the giant Asian honey bees A. dorsata and the Himalayan honey bee A. laboriosa Smith (Hymenoptera: Apidae)), larger than the dwarf Asian honey bees (A. florea). Apis cerana indica is the only Apis that has been domesticated in India (Ramachandran, 1939).…”

Ecosystems are rapidly urbanizing at the global and regional scales, particularly in the tropics, which has deleterious effect on hymenopteran pollinators. Based on the literature spanning multiple disciplines including ecology, pollination, agriculture, agroecology and entomology, this review deliberates on the pollinators and their global decline. Also, it turns the focus on honey bees and their role in agroecosystem. Relevant information from melissopalynology is brought together and the gaps and directions of future research on conservation and management of honey bees in tropical peninsular India are discussed. Focus is on the two species of the hived native Apis cerana indica F., and Tetragonula iridipennis Smith (Hymenoptera: Apidae), as these play a major role in transforming existing agricultural landscapes into agroecosystems, benefitting the farmers and maintaining ecological balance in tropical peninsular India. This review brings to the fore the fact that there is a tangible gap in reports and long-term studies of many native pollinators and in particular the two hived honey bees. Most studies present in a thorough manner visual observations of pollinators (bees) on plants but rarely combine them with quantifying the resources gathered from the plants, especially pollen. This combined approach is especially important to understand the hymenopteran pollinators from the purview of the pollination service they provide. It can be concluded that there is a pressing requirement for long-term observations along these lines with quantifiable pollen and vegetation data to arrive at meaningful plant-pollinator networks that are essential for conservation and management of the native Asiatic honey bees as pollinators.

“…The marked frames in each colony were gently taken out of the hive, and then, the gridded Mylar® sheet was juxtaposed over the surface of the bee-covered frame, and the number of grids with bees was counted and recorded. A conversion factor of two was used to calculate the bee population from the number of grids documented with bees in the evaluated frames; since the Indian bee's mean body length is 11.68 mm (Baskaran and Thiyagesan 2013), two Indian bees may occupy a single grid (cm 2 ). The frame strength (number of frames with bees) in each experimental hive was documented, and by multiplying it with the frame bee population documented, the total adult bee population per colony was arrived (Fig.…”

Colony decline has been a global challenge in recent years among the honey bee population, and no exception is Apis cerana indica F., a widely domesticated bee in India. Of the many reasons and factors suggested behind the issue, the use of insecticides is also the most linked. Insecticide residues in honey and pollen endanger honey bees and humans above a specific concentration, thus warranting our establishment of their critical daily pesticide residue exposure levels. This study developed a simple multi-residue method for analyzing neonicotinoids in honey, pollen, and bees using liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). This method had better linearity (0.005 to 0.5 µg mL− 1), the limit of detection (LOD) (0.002–0.008 µg g− 1), the limit of quantification (LOQ) (0.025 µg g− 1) and recovery (70 to 120%) for the five neonicotinoid analytes. A survey among farm colonies and a controlled field experiment detected neonicotinoid residues (0.025 to 0.456 µg g− 1) in bee products. Field experiments in sunflowers indicated that foraging neonicotinoid-contaminated food increased bee mortality in the descending order of clothianidin > thiamethoxam > imidacloprid > thiacloprid. Neonicotinoids influenced bees' foraging behavior, resulting in lower colony growth measurements (food, brood area, and bee population). Poor-quality seed sets and decreased yield in sunflower due to neonicotinoid-exposed bee colonies' poor field performance. The dietary risk evaluation of neonicotinoid residues in bees and bee products showed moderate to high risk (hazard quotient > 5) for brood and foragers and less than 1 for humans, indicating unacceptable risk to Indian bee colonies but tolerable by humans. Neonicotinoid effects must be further investigated through risk analysis in order to ensure native bees safety while following crop protection activities.
