A 50 mT static magnetic field did not affect pupa-to-adult development in Tenebrio beetle species, but modulated their motor behaviour.

Plain English Summary

Summary written for general audiences

Researchers analyzed pupa-adult development and motor behaviour of Tenebrio obscursus and T. molitor after exposure to a static magnetic field of 50 mT. The static magnetic field did not affect the pupa-to-adult developmental timing in either species. Motor behaviour of T. obscurus adults was not significantly changed by the magnetic field, but changes were seen in T. molitor.

Why This Matters

The experimental groups included a control kept 5 m from the magnets, a group placed closer to the North pole, and a group placed closer to the South pole of the magnetic dipole. Pupae were exposed to the magnetic field until the moment of adult eclosion, and development was recorded daily. After eclosion, the motor behaviour of adults was monitored in a circular open field arena, with measures including distance travelled, average speed, and immobility. In T. molitor, the direction of behavioural changes was opposite depending on whether the animals had developed closer to the North pole or closer to the South pole of the magnetic dipole.

Study Details

There is considerable concern about potential effects associated with exposure to magnetic fields on organisms. Therefore, duration of pupa-adult development and motor behaviour of adults were analyzed in Tenebrio obscursus and T. molitor after exposure to static magnetic field (50 mT).

The experimental groups were: Control (kept 5 m from the magnets), groups which pupae and adults wer...

The static magnetic field did not affect the pupa-adult developmental timing in the examined Tenebrio species.
Motor behaviour was not significantly changed in T. obscurus adults, but changes were observed in T. molitor.
Behaviour was assessed by measuring distance travelled, average speed, and immobility in a circular open field arena.
The control group was kept 5 m from the magnets, while the other groups were placed closer to either the North pole or the South pole of the magnetic dipole.
