Radiofrequency Electromagnetic Radiation

ABSTRACTMobile phones can be found almost everywhere across the globe, upholding a direct point-to-point connection between the device and the broadcast tower. The emission of radiofrequency electromagnetic radiation (RF-EMF) puts the surrounding environment inevitably into contact with this pollutant. We have therefore exposed honey bee queen larvae to the radiation of a common mobile phone device (GSM) during all stages of their pre-adult development including pupation. After 14 days of exposure, hatching of adult queens was assessed and mating success after further 11 days, respectively. Moreover, full colonies were established of five of the untreated and four of the treated queens to contrast population dynamics. We found that mobile phone radiation had significantly reduced the hatching ratio but not the mating success. If treated queens were successfully mated, colony development was not adversely affected. We provide evidence that RF-EMF only acts detrimental within the sensitivity of pupal development, once succeeded this point, no further impairment has manifested in adulthood. Our results are discussed against the background of long-lasting consequences for colony performance and the possible implication on periodic colony losses.HIGHLIGHTSChronic RF-EMF exposure significantly reduced hatching of honey bee queensMortalities occurred during pupation, not at the larval stagesMating success was not adversely affected by the irradiationAfter the exposure, surviving queens were able to establish intact coloniesGRAPHICAL ABSTRACT

In this study, the antibacterial activity of ethanol and methanol extracts of Zataria multiflora and Teucrium polium was determined against Paenibacillus alvei by disc diffusion method. Paenibacillus alvei is one secondary bacterium for the European foulbrood disease in honey bee. Minimum inhibitory concentration and minimum bactericidal concentration were determined by using the serial dilution method. For this, Z. multiflora and T. polium are collected from different areas of Iran then they are dried and extracted in lab. The antibacterial effect of alcoholic extracts of Z. multiflora and T. polium was lower than usual standard antibiotics (P<0.01), but the ethanol and methanol extracts of Z. multiflora at a concentration of 60mg/ml, have inhibitory and lethal effects on P. alvei. Also, 100mg/ml concentrations of ethanol extract of T. polium has inhibitory and lethal effects on this bacterium. But, the no one of used concentrations of its methanol extract has inhibitory and lethal effects. Results indicated that used extracts of Z. multiflora have the higher antibacterial effects than extract of T. polium on Paenibacillus alvei. It can be concluded that regarding the high antibacterial power of Z. multiflora, it is necessity to work on how they can be used in control and treatment of bacterial honey bee diseases.
