There were taken into observation 20 biological units with queen bees of different ages. It was monitored the development rhythm of natural queen cells, which are in attendance by the working bees, and to put into evidence the swarming instinct strength, so in bee keeping practice to be known and to be avoided the natural swarming. The determination of occupied surfaces with covered brood and larval was effected with the Netz framework. The aim of our study was to understand how the swarming in honeybees occurs. By detailed observation, we want to describe and to explain the behaviour of honeybees before the swarming process. The obtained results are quantified in absolute values and expressed graphically in relative values, but in the next three apicultural years (2020, 2021 and 2022), the experiment will be repeated for a variance analysis, which will provide a statistical assurance. We hope that these data will give contribution for the apicultural practice, keeping attention on queen bees’ importance during active season and on careful supervision on development rhythm of the honeybee units during the natural swarming.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

This parasite managed to switch from its natural host the Eastern honeybee, A. cerana, and within a few decades, it spread among A. mellifera populations around the world. Today beekeepers are using a variety of different acaricides to keep the parasite population under control. However, for many of these substances, the parasite evolved resistance asking for the development of novel compounds. Hence the treatment is less suited as a sustainable tool in honeybee health; consequently, other alternative options are needed, and breeding of Varroa resistant honeybees have been suggested as a more sustainable solution. Here we reviewed the successful efforts and the apicultural procedures needed to be implemented to achieve resistant honeybees. We also describe the underlying resistance mechanisms and discuss the benefits of breeding within regional populations, considering the biodiversity aspects of A. mellifera.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

At 80°C, for 120 min., the strain showed good growth (9.04 log CFU/ml). Results were sensitive to most antibiotics, with a highly susceptible (between 16 – 25 mm) to erythromycin, clindamycin, amoxicillin, chloramphenicol, ciprofloxacin, amikacin and kanamycin. The strain was found to be sensitive to vancomycin, gentamicin, and tetracycline.

In pelt’s performance-specific control activities, for quality analysis is insisted mainly on the main traits that influence the expression with a certain type or curl form. In order to create conditions for genetic expression of the desired curl shape, it is necessary to follow the improvement of the following parameters: length, height, width, degree of closure, circumferential direction, contour and layout of the pelt surface curls. The used method in the assessment of the objectives was based on the technical norms specified in Section 1.4 and 1.5 of the MADR Order no. 22 / 20.01.2006, and the statistical processing of the data was based on the use of S.A.V.C. The assessment of the type of curls in long and medium tubes shows a considerable improvement in this character since the type was identified in 65.11% of cases in 2005 and increased to 66.66% in 2015. On the respective interval, the proportion of the desired lambs increased by more than 1.5%, the difference being statistically significant for p<0.01. The proportion of lambs where the curl was predominantly of the flattened type and with a low degree of closure, respectively wave or smooth, was kept within relatively constant limits placed around 20%, with relatively reduced variations from one generation to the next.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Bacteriological isolation of Brucella sp. from meat samples was also performed. The overall prevalence of bovine brucellosis is 7.7%, 6.6%, and 4.9% by RBT, ELISA, and culture-based test respectively. Based on sensitivity and specificity, ELISA outperforms RBT in comparison to culture results as the gold standard test. Nonetheless, both tests showed good efficiency in comparison to culture approach. In terms of temporal changes of brucellosis rate, spring progress is strongly associated (r²=0.96) with increase in seroprevalence. In conclusion, the prevalence of bovine brucellosis in Erbil city is alarming.

The same, extremely significant differences are found in the CCOMn parameter after the same process, coagulation. Applying just a single treatment like: sedimentation, coagulation of raw water without being followed by disinfection does not guarantee the removal or reduction of the total number of germs in water. Disinfection with UV dose (3.40-3.88 mj/cm2) of control samples indicates a significant reduction in bacterial load depending on exposure time, with the best values obtained at the 30 minute exposure.

In 60% of samples coagulated and after that exposed to 30 minutes of UV irradiation, was found 0 TNG / ml water.

The total lipid content had values quite close to the HoneySweet and Stanley varieties, far superior to Renclod Althan variety. HoneySweet transgenic plum had the highest total protein content. Also, HoneySweet variety is distinguished by a balanced protein and lipid content.
