The diagnosis of insect venom allergy and the indication for specific immunotherapy is based on history, skin tests and demonstration of hymenoptera venom-specific IgE-antibodies. Cellular tests can add useful information but the role of basophil activation tests for the different venoms has to be elucidated further. We evaluated positive reactions in a basophil activation test using CD63 expre...

Bees are important pollinators of plants in both agricultural and non-agricultural landscapes. Recent losses of both managed and wild bee species have negative impacts on crop production and ecosystem diversity. Therefore, in order to mitigate bee losses, it is important to identify the factors most responsible. Multiple factors including pathogens, agrochemical exposure, lack of quality forage...

Eusocial honey bee populations (Apis mellifera) employ an age stratification organization of egg, larvae, pupae, hive bees and foraging bees. Understanding the recent decline in honey bee colonies hinges on understanding the factors that impact each of these different age castes. We first perform an analysis of steady state bee populations given mortality rates within each bee caste and find th...

The multi-species associations of insects (symbiocenosis) in honey bee hives currently include more than 15 orders Insecta. We present the results studying inquilines south Western Siberia. In honeybee this region 37 insect species from 8 (Dermaptera, Thysanoptera, Psocoptera, Hemiptera, Coleoptera, Hymenoptera, Lepidoptera, Diptera) were identified. Inquiline observed 77% 81.5% studied apiarie...

Forests provide potentially important bee habitat, but little research has been done on forest bee diversity and the relative effectiveness of bee sampling methods in this environment. Bee diversity and sampling methodology were studied in an Illinois, USA upland oak-hickory forest using elevated and ground-level pan traps, malaise traps, and vane traps. 854 bees and 55 bee species were collect...

Individual honey bee Apis mellifera L. queens were examined for the presence of six honey bee viruses including acute bee paralysis virus, chronic bee paralysis virus, black queen cell virus, deformed wing virus, Kashmir bee virus, and sacbrood virus. All viruses, except ABPV, were detected in the samples. Among queens examined for virus infections, 93% had multiple virus infections. The detect...

This paper is the use of modern information technology, research the quality of bee product tracking and traceability system based on Agent. On the one hand, through establish the quality of bee product tracking and traceability system, to provide a technical support and general-purpose tools, it includes bee products from production to sales for the entire process digital, visual expression, d...

In this paper we present a modification of artificial bee colony (ABC) algorithm for constrained optimization problems. In nature more than one onlooker bee goes to a promising food source reported by employed bee. Our proposed modification forms a mutant solution in onlooker phase using three onlookers. This approach obtains better results than the original artificial bee colony algorithm. Our...

Bee stings can cause severe adverse reactions, leading to anaphylaxis, cardiovascular collapse, and death. In some cases, bee venom also induces disseminated intravascular coagulation (DIC). However, to our knowledge, there has been no fatal case of intravascular coagulation accompanied by anaphylaxis caused by bee sting acupuncture. Here, we report a fatal case of a 65-year-old woman with DIC,...

background: prelacteal feeding is an underestimated problem in a developing country like india, where infant mortality rate is quite high. the present study tried to find out the factors determining prelacteal feeding in rural areas of north india. methods: a crosssectional study was conducted among recently delivered women of rural uttar pradesh, india. multistage random sampling was used for ...
