§ 105. Mr. Bryant Godman Irvineasked 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 MackieThe 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.
