THE RAGWORT MOTH.
INVESTIGATIONS IN WAIKATO. Mr Barugh, of Hamilton, a,ccfc>mpaniel by three officers from the Government Experimental Farm at Ruakura, visited Mr T. T. Hicks’ farm at Maungatautari on Saturday last, to investigate the report that moths and grubs which destroyed ragwort had made their appearance; there. The party found thousands of moths and caterpillars on the ragwort plants. Fr,o:n his personal observations Mr Hicks is convinced that the moth in question is a deadly natural enemy of the weed, considerable destruction having already beqn wrought by the .species amongst plants on his property. As yet it is too early to say with c.ertainty that they kill, t'he gagwort outright, but. evidence points that way.
In the meantime samples of the attacked plants and seed, and of the moths themselves, are .being forwarded to the Cawthron Institute for exhaustive tests. The results will be awaited with interest, for, as previously mentioned in this paper, we appear to! have in this country an indigenous moth that will apparently do tlie woi;k expected of the exotic one, and without the potential danger consequental to the release of t'he latter.
