Abstract Honey bees are globally regarded as important crop pollinators and are also valued for their honey production. They have been introduced on an almost worldwide scale. During recent years, however, several studies argue their possible competition with unmanaged pollinators. Here we examine the possible effects of honey bees on the foraging behaviour of wild bees on Cistus creticus flowers in Northern Greece. We gradually introduced one, five, and eight honey-bee hives per site, each containing ca. 20,000 workers. The visitation frequency and visit duration of wild bees before and after the beehive introductions were measured by flower observation. While the visitation frequencies of wild bees were unaffected, the average time wild bees spent on C. creticus increased with the introduction of the honey-bee hives. Although competition between honey bees and wild bees is often expected, we did not find any clear evidence for significant effects even in honey-bee densities much higher than the European-wide average of 3.1 colonies/km2.

The Impact

AbstractForaging honey bees were offered various sucrose–herbicide solutions. Despite the visual attractiveness of the feeding dishes to foragers, six of seven herbicides significantly reduced the incidence of feeding and were judged to be olfactory and gustatory repellents. The most repellent herbicide was 2,4,5-T, which totally inhibited feeding at concentrations as tow as 1000 ppm. The next most repellent was 2,4-DB, followed by linuron, picloram, 2,4-D, and monuron. Paraquat was the only herbicide that did not exhibit marked repellency at concentrations up to 4000 ppm.The implications of these findings are discussed in terms of the impact of herbicide applications on honey bee foraging behaviour, brood development, pollination, and honey production.

Honey Bee Foraging

The foraging of honey bees is one of the most well organized and admirable behaviors that exist among social insects. In behavioral studies, these beautiful insects have been extensively used for understanding time-space learning, landmark use and concept of learning etc. Highly organized behaviors such as social interaction and communication are systematically well organized behavioral components of honeybee foraging. Over the last two decades, understanding the regulatory mechanisms underlying honey bee foraging at the cellular and molecular levels has been increasingly interested to several researchers. Upon the search of regulatory genes of brain and behavior, immediate early (IE) genes are considered as tool to begin the investigation. Our two recent studies, have demonstrated three IE genes namely Egr-1, Hr38 and kakusei having a role in the daily foraging of bees and their association with learning and memory during the foraging. These studies further evidence that IE genes can be used as a tool in finding the specific molecular/cellular players of foraging in honey bees and its behavioral components such as learning, memory, social interaction, social communication etc. In this article we provide the details of the method of sample collection at different times during foraging to investigate the foraging regulatory molecules. Key words: Honey bee foraging, learning and memory, immediate early genes, Egr-1, Hr38, Kakusei.

This study aims to analyze the feasibility of the business and analyze the opportunities and threats of Trigona Ongka farm in Laompo Village, Batauga District, South Buton Regency. The research was conducted from January to February 2020 in Laompo Village, Batauga District, South Buton Regency. The sample in this study was 1 (one) honeybee breeders (Trigona sp). The method used is the independent sample t-test and the R / C feasibility analysis. Business opportunities and threats are analyzed qualitatively. The results showed that the business feasibility of Trigona sp honey bee livestock through the STUP and topping method was 1.5, (R/C > 1), meaning that each additional cost incurred resulted in a larger increase in revenue as much as IDR 1,400,000 for the STUP method and IDR 1,500,000 for the topping method instead of additional costs or simply profitable business activities. The honey bee livestock business opportunity of Trigona sp, namely honey as a favorite that is popular, relatively stable price, partially known production of the community, the location is easy to reach by vehicles, the availability of large land for business development. While the threat of Trigona sp honey bee livestock, namely: lack of environmental carrying capacity, so that environmental improvements and increasing the number of bee colonies are needed to increase honey production, do not have a product brand to be widely commercialized, product quality standardization is still poorly understood by breeders, there is no internal coordination between breeders to strengthen institutions and lack of access to assistance from capital institutions in terms of capital.  Keywords: Prospects, Business Feasibility, Honey Bees

Although kin selection is commonly regarded as a major force in the evolution and maintenance of social behaviour in eusocial insects, recent controversy regarding whether honey bee (Apis mellifera L., 1758) workers can discriminate close kin from more distant relatives casts doubt on the extent to which cooperation among individuals within honey bee colonies is controlled by genetic relatedness. We contrasted brood and honey production in colonies where we diluted worker relatedness with those elements of productivity in colonies where relatedness was unmanipulated. Relatedness manipulation did not affect overall brood production, worker or drone brood production, the worker to drone brood sex ratio, or the volume of honey produced. Thus, there is no evidence that honey bees discriminate close from distant relatives or, more importantly, that dilution of the coefficient of relatedness within a colony has any impact on the efficiency of that colony.

Decline in honey bee populations has become a matter of concern and their conservation is very essential to sustain essential ecosystem services. They provide making available continuous supply of floral resources is of immense value in conserving honey bees. The effectiveness of an ornamental creeper, Antigonon leptopus Hook. & Arn as a sustainable bee forage plant was evaluated. It attracts four major native species of honey bees viz., Apis cerana, A. florea, A. dorsata and Tetragonula iridipennis. The wild little bee, A. florea was the most dominant forager followed by the Indian bee, A. cerana. The plant is amenable for easy multiplication through seeds as well as cuttings and meets both aesthetic and ecological needs. Using Antigonon, different studies related to honey bees like assessing species diversity, foraging behaviour, temperature driven shifts etc. can be carried out. Popularising perennial bee flora like Antigonon would help in conserving honey bees in both natural and urban habitats. Since Antigonon attracts all species of honey bees throughout the year, it could be utilized as a potential bioindicator of honey bee populations in a given environment.

Honey Bee Colony

Foraging behaviour is one of the distinctive behaviours of honey bees, Apis mellifera. This behaviour is the link between the honey bee colony and the ambient environment. Therefore, various in-colony and out-colony factors have an impact on this behaviour, and many studies have been employed to investigate these factors. Foraging behaviour is not advantageous only for the colony and for plant pollination but also has other benefits. In contrast, some disadvantages have also been discovered to be linked with foraging activity. Practically speaking, the control over this behaviour is very important to maximize colony products as well as to increase other agricultural benefits. This paper presents a review on foraging activity including; the regulation of foraging tasks, factors impacting this behaviour, foraging preference, variations between subspecies, monitoring methods as well as the possible methods for controlling this behaviour. As concluded from this review, more work needs to be performed in order to elucidate certain aspects of foraging behaviour.

Before And After

The honey bee (Apis mellifera) is an ecologically and economically important species that provides pollination services to natural and agricultural systems. The biodiversity of the honey bee is being endangered by the mass import of non-native queens. In many locations, it is not clear how the local populations have been affected by hybridisation between native and non-native bees. There is especially little information about temporal changes in hybridisation. In Romania, A. m. carpatica naturally occurs, and earlier studies show that there are two subpopulations separated by the Carpathian Mountains. In this study, we investigated how the arrangement of veins in bees’ wings (venation) has changed in Romanian honey bees in the last four decades. We found that in the contemporary population of Romanian bees, there are still clear differences between the intra- and extra-Carpathian subpopulations, which indicates that natural variation among honey bees is still being preserved. We also found significant differences between bees collected before and after 2000. The observed temporal changes in wing venation are most likely caused by hybridisation between native bees and non-native bees sporadically introduced by beekeepers. In order to facilitate conservation and the monitoring of native Romanian bees, we developed a method facilitating their identification.
