“…Honey bees maintain the inside colony temperature fairly constant over the season (Seeley, 1985). Temperature of the brood area is narrowly controlled to be 35°C for optimum larval development while the temperature inside the bee ball cluster during winter is around 21-24°C (Farhenholz et al, 1989;Yi and Jung, 2010;Jeong et al, 2016). However, foraging is largely limited by the outside temperature because of the small sized-body with high energy demand for flight muscle movement (Seeley, 1985).…”

Background: Pollen is an important source of protein and lipids for many animals including honey bees. In order to understand the foraging behaviour of honey bee colonies and preference among the available floral resources, pollen collections from three experimental healthy colonies of honey bees were analysed in the month of June. Results: The amount of pollen collections were related to the colony's need which was indicated by the number of larval and adult bees present in the hive. Interesting was the sequence of pollen collection from different floral sources. All honey bee colonies collected pollens from Trifolium repens first, then Erigeron annus and the third choice was Coreopsis drummondii and Oenothera biennis flowers. Total protein content of Trifolium pollen was the highest (20.0 g/100 g DM), and the others were in the range of 8.9-11.4 g/100 g DM. Conclusion: The results indicated that the first criteria for honey bee foraging preference of pollens would be the nutritional contents of protein and the resource availability of the lesser nutritious floral sources. This information can help pollinator protection programmes of habitat manipulation using flowering plants for nectar and pollen sources.

“…During our investigation, V. v. nigrithorax was not captured in Jeju Island, the southernmost part of Korea. Records in Jeju (six points) were excluded from the abundance database, as it was unclear whether the absence of this species was due to geographic or ecological barriers 12 , 45 . A total of 248 records were compiled to represent abundance data of V. v. nigrithorax (Supplementary Fig.…”

“…We expected this standardized NFA data to have a closer relationship with the abundance of V. v. nigrithorax in a given area. In addition to the NFA data, we collected information about the appearance rate of V. v. nigrithorax in apiaries in the province (-do) level of Korea 12 . This data was constructed through questionnaires answered by beekeepers to investigate the appearance of hornet species in Korea, including % rate of each species in apiaries in a given administrative unit.…”

“…Although its impact varies depending on the surrounding habitat and food availability, this species is generally considered as problematic in the beekeeping industry due to its frequent predation of honeybees 7 , 10 – 13 . The estimated annual cost of managing hornet species in Korean apiaries exceeds $60,000,000, with V. v. nigrithorax contributing significantly to this expense 12 .…”

The Asian yellow-legged hornet, Vespa velutina nigrithorax, is native to Southeast Asia. However, it has invaded many countries in temperate regions, causing serious threats to honeybees and human health. With a growing demand for estimating the potential distribution of this species, multiple studies have resorted to occurrence-based models. However, they are less informative for predicting local abundance patterns associated with the species’ impact. Thus, we aimed to develop an abundance-based distribution model for V. v. nigrithorax in Korea to support the forecast of its impact and associated management strategies. The abundance data of V. v. nigrithorax were collected from 254 sites for 4 years covering the country and used to develop a model with bioclimatic and land composition variables. Along with the abundance model, the classical occurrence model was tested to determine whether it could provide a reasonable prediction on the estimation of local abundance. As a result, the abundance model provided higher discriminative power and accuracy than the occurrence model to evaluate the impacts caused by V. v. nigrithorax. On the other hand, the occurrence model was not able to discriminate abundance in the areas occupied by V. v. nigrithorax, indicating an unclear occurrence-abundance relationship or oversimplification of the estimated niche created by the occurrence model. Based on the final abundance model, risk indices for human health and honeybee losses were suggested. These results could help to provide support for risk management of V. v. nigrithorax in Korea and to give biological information to other countries where this species has already become established or which it is likely to invade in the near future.

“…This infestation has been linked to reduced honey bee colonies in various parts of the world, including the United States (30%), Europe (up to 53%), the Middle East (10–85%), and Japan (25%) as the United Nations Environment Programme (UNEP) emerging issues reported [ 9 ]. It was also reported that V. destructor has been the most significant threat to honey bees colonies in Korea [ 10 ], the United States [ 11 ], and New Zealand [ 12 ].…”

The honey bee (Apis mellifera) faces a significant threat from Varroa destructor, causing the losses of millions of colonies worldwide. While synthetic acaricides are widely used to control Varroa infestations, excessive application has led to resistant strains and poses side effects on the host. Consequently, there is an urgent need for a new acaricide that is both effective and affordable, yet safe to use on bees. One potential source of these acaricides is essential oils (EOs) and their constituents. This study evaluated the acaricidal properties of four essential oils (Eucalyptus globulus, Rosemary officinalis, Trachyspermum ammi (Ethiopian and Indian varieties), their constituents and mixture of constituents against V. destructor through the complete exposure method. Our finding showed that a 1:1 mixture of thymol and carvacrol (4 h-LC50 = 42 μg/mL), thymol (4 h-LC50 = 71 μg/mL), and T. ammi oil (4 h-LC50 = 81–98 μg/mL) were the most toxic test samples against V. destructor. Honey bee behavior and selectivity were also assessed with one additional EO Thymus schimperi, indicating that T. schimperi, T. ammi, and their components were selective and did not affect the learning and memory of bees. In conclusion, the thymol and carvacrol (1:1) mixture was shown to be a promising replacement for synthetic acaricides, being three times more toxic than a commercial acaricide, fluvalinate (4 h-LC50 = 143 μg/mL).
