The article concerns using spring honey yield in the Western Ukrainian region. The spring honey yield distinctions in Lviv oblast are given, where honey yielding plants diversity provides not rapid bees' families development only but makes it possible to obtain healing May honey. Bees' families development is examined, when the necessity of nest's enlarging arises. Active bees' brood growing takes place. The necessity is stated to prepare bees' families for the early spring honey yielding which may manifestate itself in limitating egg laying by queen, that will allow to convert part of feed honey into commercial. All the moments are gragually considered as to using the May honey yield , from strengthening a family with a brood to the subsequent widening a nest. A positive role of using extensions in long hives (early spring honey yield increases by 1.5-2 times). Besides due to the extensions the mature honey is obtained of higher quality. The significance is analysed of the hive design for early honey yield. The hive design, honey-providing base andbeekeeping technology are concluded to be the key factors of beekeeping management

A four frame radial type motor driven bee honey extractor was designed, fabricated and evaluated based on the recommendations of bee honey producers and designers of the old model extracting machine. It is composed of four main parts, namely: the cylinder collector, the primeover and power transmission group, the frame assembly and the support assembly. The device was designed to operate using 373 watts capacitor start-capacitor run electric motor capable of reversing the shaft rotation. All materials of construction exposed and in contact to the extracted bee honey were made of stainless materials. The device operates by the principle of centrifugal action where honey from the uncapped honey-combs throws out of its shell during rotation. Both sides of the comb were extracted radially orienting the frame assembly and rotating it in reversing directions. Analysis of data using 3 x 3 factorial experiment in completely randomized design and Duncan Multiple Range Test, the device has the observed highest extracting efficiency of 96.39% at 300 +/-5 rpm rotation of the frame assembly. Moreover, operating the device at 7 min duration yielded also the highest extracting efficiency of 96.39% at 300 +/-5 rpm rotation of the frame assembly. Moreover, operating the device at 7 min duration yielded also the highest extracting efficiency of 95.73% as compared to 3 min and 5 min duration. The highest performance efficiency obtained ranged from 86.27% to 87.70% at frame rotations of 250 +/-5 rpm and 300 +/-5 rpm, respectively. Also, operating the device at 5 min and 7 min duration yielded the highest performance efficiency range of 86.52-87.75, respectively. The device has a capacity of extracting four frames at a time with the highest observed value of 1.471 kg/min at 300 +/-5 rpm and 3 min duration. With respect to time of operation, the highest capacity observed was 1.321 kg/min at 3 min duration and with respect to the rotation of the frames, it was 0.953 kg/min at 250 +/-5 rpm. The minimum amount of honey to be extracted per year to justify the economic feasibility of using the device at a custom rate of Php5.00/bottle charge for extraction was 511.26 bottles with an 8 oz capacity

A semi-field method was developed to assess the side-effects of systemic seed dressings or systemic soil treatments with plant protection products on honeybees (Apis mellifèra), which allows a direct pre- and post-treatment comparison of the effects. The proposed methodology takes also into account the requirements outlined in the EPPO 170, BBA VI,23-1 and C.E.B. 129 guidelines. The study design is based on the release of bees in a bi-tunnel system: two adjacent tunnels, each 20 m x 8 m wide and a height of 3.5 m at the highest point, covered with a white fine mesh plastic netting. Three replicated bi-tunnels per treatment and the control are set up. In all the control plots, both tunnels of each replicate are untreated and therefore planted only with control plants, while in the test item replicates one tunnel is untreated (i.e. planted with control plants) and the second tunnel is treated (e.g. dressed seeds, treated soil). In order to prolong the exposure time of the bees (flowering plants available over a longer period), the crop planting is staggered. Bee colonies headed by sister queens with a size of approximately 10000-15000 bees will be set up at one end of the bitunnel between the 2 tunnels. Each hive is provided with a pollen trap, a dead bee trap and Apiscan. A removable netting between the two tunnels allows to control in which tunnel(s) the bees will be able to forage. The complete study consists of 3 successive periods of exposure (each exposure 5-7 days) of the bees: (1) bees will be allowed to invade the untreated half of the bi-tunnel and the behavior of each individual colony will be assessed, (2) the netting separating the 2 tunnels will be removed and the bees will be allowed to freely invade the treated and untreated areas (dynamics of invasion and the behavior of colonies will be assessed in order to study potential repellent effects) and (3) the bees will be confined in the second tunnel (treated tunnel) and behavior of colonies observed
