Abstract Honey bees (Apis cerana Fabricius) were collected from 195 colonies at seven different localities spanning the main beekeeping areas in Huangshan. Morphometric methods were used to measure seven standard morphometric characters, and these bees were compared to samples from the Henan, Shandong, and Yunnan provinces. Principal component analysis of the total Huangshan database yielded two clusters: bees from Jinxian and Jixixian, and those from other localities. Within the latter cluster, discriminant and hierarchical cluster analyses revealed overlapping regional sub-clusters: bees from Huangshanqu, Qimenxian, Huizhouqu, and Shexian, and those from Yixian. Significant differences between the means of the three clusters were demonstrated using Wilks’ lambda statistic. Morphocluster separation was related to altitude differences. Moreover, we noted some regions with high intercolonial variance, suggesting introgression among these defined honeybee populations.

Honey is one of the historical natural products produced by honey bees. Humans used it as medicine and protection against some infectious diseases, a honey quale is dependent in its classification of the honey bee. The most famous accomplished honey bees in the world are Africanized honey bee (Apis mellıfera .l), Western honey bee or European honey bee (Apis mellifera), Eastern honey bee (Apis cerana),  Philippine honey bee (Apis nigrocincta), Koschevnikovs honey bee (A. koschevnikovi), Giant Honeybees (Apis dorsata), Dwarf Honeybees (Apis andreniformis). This study collected the health effect, quality and usage of honey in several industries; also argue about the nutritious value of honey that the most important parts are protein, carbohydrates, vitamin, and minerals. Honey is not only a nutrient it also plays a major role in many other products, uses of honey in cosmetics as a protective and softener of skin, it is used up to 22% in paste masks and mud packs (which are considered rinse-off formulations). Uses of honey in Ayurveda for prevention of irritation, cough, healthy teeth, gums, and boons.  Production of honey has been compared in 2013 to 2018, in 2013 the world production of honey was 1,664 thousand tones with an increase of 1/3 in just two decades. China, where manufacturing amounted to 466.3 thousand tons, i.e. approximately 29% of the global volume of output, these are showing that China was the biggest producer of honey in the world but it gets a decrease in 2018 as well as Brazil, America, Russia, Ethiopia, and Iran. And it increases in Turkey, Argentine, India, Mexico, and Poland.

Systematics of honey bees has developed rapidly. Several studies have attempted to infer the kinship between each group of honey bees.  One approach is the use identification and phylogenetic analysis using combination of morphology, morphometric, and molecular characteristics data. There are three species of honey bees found in the Central Sulawesi, namely Apis dorsata, A. cerana and A. nigrocincta. The last two species mentioned have similar biological properties, so they present some difficulties to identify especially with morphological characters only. The results showed that the two Apis bee species analyzed in this study, had similar morphological features compared to specimens of the same species from the other regions, whereas the morphometry of the two had variations in size compared to the same species that have been reported in other regions. The variations in the size or morphometric character of worker bees, both those with a larger or smaller size, possibly being a form of morphological adaptation to different environmental conditions. The CO1 and 16S Mitochondrial DNA sequencesof A. cerana and A. nigrocincta from this studywere similarto thesequences of the same species in the GeneBank’s database. This study provide preliminary data contributing to the preservation and utilization of one of Indonesia’s important biodiversity resources.

Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.
