Bee queen development under GSM exposure
The reported finding
Reduction from original grafts to hatching:30.8% controls versus 61.5% exposed,LogRank P=.0065. Overall mortality HR2.3,P=.003; mating among hatched queens and later colony sizes not significantly different.
Reading it carefully
Only two rearing-colony pairs; colony nesting remains a limitation. Handset exposure is explicitly an unrepresentative worst-case apiary scenario; human SAR rating does not measure bee absorption. No established colony-collapse cause.
Inside the study
Exposure conditions
900 MHz GSM AEG handset attached to grafting frame;15 two-minute calls/day for about 14 days; queen cups within~21 cm. Off-phone controls. Human phantom handset SAR0.59/1.16 W/kg is not bee SAR.
Design & controls
Two paired queen-rearing colony replicates;26 grafted larvae per treatment/replicate,52 per treatment total. Hohenheim 2018; surviving queens tested for mating and 9 subsequent colonies followed to day 88.
Related research & shared cohorts
Hohenheim programme, distinct experiment/setup from Treder 2023. Shared institution does not establish shared colonies.
The protection question raised
Is the reduced queen hatching reproducible under well-characterised, environmentally relevant exposure? Two colony pairs and an unusual handset arrangement limit translation to bee populations or wider colony losses.
