This decline has caused cascading effects on the region's community structure and ecosystem stability. To improve the protection of native bees in the natural and agricultural landscape of the Qinling Mountains and its surrounding areas, we investigated 33 sampling sites within three habitats: forest, forest-agriculture ecotones, and farmland. Using a generalized linear mixing model, t-test, and other data analysis methods, we explored the impact of Apis mellifera on local pollinator bee richness, abundance, and the pollination network in different habitats in these regional areas. The results show that(1)Apis mellifera significantly negatively affects the abundance and richness of wild pollinator bees,while Apis cerana abundance is also affected by beekeeping conditions.(2)There are significant negative effects of Apis mellifera on the community structure of pollinator bees in the Qinling Mountains and its surrounding areas: the Shannon-Wiener diversity index, Pielou evenness index, and Margalef richness index of bee communities at sites with Apis mellifera influence were significantly lower than those at sites without Apis mellifera influence.(3)The underlying driver of this effect is the monopolization of flowering resources by Apis mellifera. This species tends to visit flowering plants with large nectar sources, which constitute a significant portion of the local plant community. By maintaining a dominant role in the bee-plant pollination network, Apis mellifera competitively displaces native pollinator bees, reducing their access to floral resources. This ultimately leads to a reduction in local bee-plant interactions, decreasing the complexity and stability of the pollination network. These findings highlight the need for targeted conservation efforts to protect native pollinator species and maintain the ecological balance in the Qinling Mountains.展开更多

[Method] Using sample area survey and netting method in the fixed points to investigate species and quantities of Asian sacred lotus, the species diversity of different locations was evaluated by diversity indices (H′), evenness indices (J) and dominant concentration indices (C). [Result] Apis mel ifera, Apis cerana cerana, Xylocopa (Koptortosoma) sinensis, Xylocopa (s.str.) valga and Xylocopa (Al oxylocopa) appendiculata, al of which belong to order Hy-menoptera were the main pol inators of lotus. Temperature was the main factor which influenced the foraging behaviors of flower-visiting insects. The daily activities of X. (s.str.) valga and X. (Al oxylocopa) appendiculata were bimodal, and that of A. mel-lifera, A. cerana cerana and X. (s.str.) valga were unimodal. The percentage of wild pol inators in Linxiang of Hunan Province and Xianning of Hubei Province were only 20.59% and 3.90% respectively, and there were six species of flower-visiting insects in Linxiang and three in Xianning. The percentages of wild pol inators in Shicheng of Jiangxi Province and the lotus garden in Huazhong Agricultural University were 55.61% and 90.40% respectively, and the flower-visiting insects belonged to 13 and 12 species respectively. The diversity index (H′) and evenness index (J) were listed here in a decreasing order: Shicheng of Jiangxi >lotus garden in Huazhong Agricul-tural University>Linxiang of Hunan >Xianning of Hubei. The sequence of dominant concentration indices (C) was Shicheng of Jiangxi <the lotus garden in Huazhong Agricultural University<Linxiang of Hunan<Xianning of Hubei. The diversity indices (H′), evenness indices (J) and dominant concentration indices (C) of each sample location were consistent. [Conclusion] The species and quantities of Asian sacred lotus vary in different ecological areas. The species and quantities of Linxiang in Hunan Province and Xianning in Hubei Province are rare. The increase of lotus production must depend on bee pol ination.展开更多

Observations were made on 340 flowers each year and divided in three treatments. The treatments included unlimited flowers access by all visitors; bagged flowers to deny all visits and limited visits by Apis mellifera adansonii only. The worker bees seasonal rhythm of activity, its foraging behaviour, its pollination efficiency, the fruiting rate, the number of seeds per fruit and the percentage of normal seeds were evaluated. Results show that this bee foraged G. hirsutum flowers throughout the whole blooming period. This bee species intensely harvested pollen and nectar. The mean foraging speed was 9.41 flowers per rain in 2009 and 8.41 flowers per min in 2010. The fruiting rate, the number of seeds per fruit and the percentage of normal seeds of unprotected flowers were significantly higher than those of flowers protected from insects. Through its pollination efficiency, Apis mellifera adansonii provoked a significant increment of the fruiting rate by 60.84% in 2009 and 36.48% in 2010, as well as the number of seeds per fruit by 94.16% in 2009 and 31.41% in 2010, and the percentage of normal seeds by 94.23% in 2009 and 33.49% in 2010. The installation ofA. m. adansonii colonies close to G. hirsutum fields could be recommended to increase fruit, seed and honey yields, and pollen production as a hive product in the region.展开更多

In 2009, residues were found in pollen samples from twelve locations (40%), in 2010, in samples from four locations (13.3%) and in 2011, in samples from three locations (10%). Altogether 15 different residues in pollen were found in 2009, two in year 2010 and five in 2011. Residues found in the pollen samples ranged from 0.001 mg/kg to 76 mg/kg. The highest number (twelve) of residues was found in pollen from the intensive fruit farming locations and from the intensive viticulture locations (eight). The residues were mostly from the fungicide group (69%). Insecticide residues (chlorpyrifos-ethyl, methoxyfenozide, thiacloprid) were found in the pollen samples from eight locations. Residues in the pollen did not statistically influence the development of the honeybee colonies or infestation rate of Nosema (Nosema spp.), or viruses ABPV (acute bee paralysis virus), SBV (sacbrood virus), DWV (deformed wing virus), and BQCV (black queen cell virus)).展开更多

Agricultural production sector does not fully recognize the economic value of honeybee pollination. Chinese beekeepers gain profits only from products such as honey, royal jelly and bee pollen. Because of the production mode that aims at gathering and producing more honey while neglecting the health care of bees and the quality of products; export enterprises lack guidance and knowledge in export inspection and quarantine and technical regulations, and thus, the average price of China's bee honey exports is much lower than that of other countries in the world. Meanwhile, in domestic market, given the sustained development of China's macro economy and increasing incomes of residents, people show increasing interests in the health care function of honey. Based on the survey data of honey market in Beijing, Hangzhou, Qingdao, Zhengzhou and Chengdu from 2012 to 2015, the paper analyzes the price feature of China's honey market and its formulation basis, and also compares prices of honey with the same quality in different markets. Moreover, the paper combines data from fixed observation places of honey products production, which is carried out by the economic research group of bee industry in 11 provinces, to discuss reasons for continuous honey price rising in domestic market. Lastly, the paper uses the honey as an example to analyze pricing strategy of agricultural products with health care functions. The paper hold the opinions that the keys to solve the problem that high quality agricultural material couldn't sell in high price and good and bad are mixed in the market, is to build up quality and price mechanism in the processing of raw material purchasing to the terminal market, publicize more products information and superior customer attractiveness on health care effect.展开更多

In this research, the antiulcer activity of wild honey produced by Apis dorsata, alone or in combination with Turmeric Rhizome, was evaluated in healing acute gastric ulcer. Male Wistar albino rats(150–250 g) were induced ulcers with aspirin at 405 mg/kg BW and ethanol. Antiulcer evaluation was done based on the gastric acidity, numbers and diameter of ulcers, ulcer index, healing ratio, histological examinations, and body weight. The results showed that the groups given honey alone, turmeric alone, and combination of turmeric-honey displayed significant ulcer healing compared to the control group. Ulcers in the group administered with combination of turmeric-wild honey was different significantly from the turmeric alone and wild honey alone groups with increased body weight in that group. The result showed that wild honey(2125 mg/kg BW) had the greatest activity in healing ulcers among other groups. The combination of turmeric-wild honey had a good activity in healing ulcers and increased the body weight of the group.展开更多
