HC Deb 27 July 1966 vol 732 c288W
105. Mr. Bryant Godman Irvine

asked the Minister of Agriculture, Fisheries and Food what study he has made of United States experiments to control pigeons by introducing a reproductory inhibitor into the bait; and what conclusions he has reached.

Mr. John Mackie

The work being done in the United States of America on reproduction inhibitors for the control of pigeons is being watched with close interest. A limited amount of work done in the laboratory appears to have given promising results but reports of field experiments so far received have not enabled any conclusions to be reached.
