HESSIAN FLY.
INTRODUCTION OF NATURAL . ENEMIES.
[Press Association.]
CHRISTCHURCH, Fob. 12
About the middle of January last the attention of Mr. A. McPherson, Superintendent of Experimental Stations in tho South Island, was drawn to some affected wheat and barley in the Totaratahi district, Otago, and he sent specimens to the Government Biologist (Mr. T. AY. Kirk), who reported that the wheat and barley straws contained, as suspected, Hessian fly pupae, and also one lies-bin fly, which had emerged in transit. Mr. Kirk stated that the. Department of Agriculture some years ago, when the fly was causing serious damage in New Zealand, imported and liberated a number of natural enemies of the lly—semiotollus pigripes and platygaster minutus —and from the straws received from-the Totaratahi district, when placed in a. breeding case, eight of these useful little insects emerged. This showed, Mr. Kirk added, that those natural enemies of the fly are still plentiful in the Dominion, and will, he felt sure, soon breed and control tho post, as they have done in past years.
