A well-studied insect was used to investigate the effects of strong magnetic fields in close proximity to the high voltage power lines on flying insects. Locusts were divided into the following groups: exposure to a magnetic field with a magnetic flux density of 1) 1 mT, 2) 4 mT or 3) 7 mT. For each exposure group and test, a separate sham exposure group was used. Different groups with different numbers of locusts were used in the individual tests:
circular glass chamber (15 cm diameter x 7.5 cm height)
Setup
a coil of 20 cm diameter and composed of 282 turns of insulated copper wire produced a homogeneous, vertical field; glass chamber with 6 locusts was placed inside the coil; temperature during exposure was monitored (at 1 mT, no change was observed (room temperature, 21°C), at 4 mT it was 24.5°C ± 1°C and at 7 mT it was 29.3°C ± 1°C)
during sham exposure, a hot plate under the coil was used to ensure the same temperature in the glass chamber as during exposure (not necessary for 1 mT)
cognitive/behavioral endpoints: motor activity (movement from one end of a tunnel to the other end with other locusts, food and light as attracting stimuli; number of animals reaching the other end of the tunnel and moved distance/time; video recording)
