# ECO-003 — Bee queen development under GSM exposure

Why this matters
Fewer queen larvae reached hatching in the exposed group. Because queen development is central to a bee colony, this is a meaningful outcome for environmental assessment. Only two pairs of rearing colonies were studied under an unusual handset-exposure arrangement; the result cannot establish a cause of wider colony losses.

Exposure: 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: 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.

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.

Boundary: 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.

Related: Hohenheim programme, distinct experiment/setup from Treder 2023. Shared institution does not establish shared colonies.

Protection Question: 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.
