The effects of high voltage transmission lines on honey bees. Interim report. [765 kV transmission line]
Results of the first year's field study of possible effects on honey bees of a 765 kV transmission line are reported. Conventional hives and metal-free hives, shielded and unshielded, were placed under the line (E-field, ca. 7 kV/m) and in a control area (E-field, ca. 10 V/m) about 400 m away. Bees in unshielded conventional hives under the line weighed less, stored little honey whose moisture content was subnormal (hive weight gain was essentially zero), propolyzed hive entrances excessively but not completely, produced fewer pupae but normal numbers of eggs and larvae, and failed to survive the winter. Unshielded metal-free hives under the line had the following normal features: bee weight; hive weight gain; honey moisture content; and number of eggs, larvae, and pupae. Their abnormal features were: propolization of hive entrances, but at a slower rate and to a lesser extent than conventional hives; aggressive clusters of bees at lower front hive corners; poor overwintering survival; and possibly higher hemocyte counts.
