WAR ON NOXIOUS WEEDS
ACCLIMATISATION OF MOTHS SUCCESS AGAINST RAGWORT (From Our Resident Reporter) WELLINGTON, To-day. Good success is attending the efforts of the Department of Scientific and Industrial Research to acclimatise a moth which attacks ragwort. The moth, known .scientifically as tyria jacobeaea, is thriving so well that it is being released in four selected districts within two years of being introduced to New Zealand. Stratford, Southland, Te Puke and Cawthron (Nelson) have been chosen. There its activities will be carefully observed. The endeavour to accustom to this climate a moth which is the foe of blackberry has not been so successful. This moth, which comes from the south of France, needs high temperatures, but new methods are being tried. The fact that the gorse in Otago is latest-flowering in the Dominion has led to that province being selected as the home of the gorse-moth, a fairly new arrival, which has missed the gorse bloom in other parts of the country. This moth is being carefully watched.
