CONTROL OF RAGWORT.
USE OF CATERPILLARS. ■ (Br CABLE—PfIBSS ASSOCIATION— COPTEIOHT.) (AUSTRALIAN AND N.Z. CABLE ASSOCIATION.) CANBERRA, November 15. Senator McLachlan announced that arrangements had been made by the Council for Scientific and Industrial Research to supply Dr. Tillyard, of the Cawthron Institute, Nelson, with a large number of the caterpillars of the Moth Momceosoma, a natural enemy of rho ragwort, for testing on plants at ilia Cawthron Institute.
Preliminary investigations carried oat by the council's entomologist ■demonstrated convincingly that these insects were capable of destroying ragwort plants in a week or so. Should starvation tests prove satisfactory it is expected that these caterpillars will assist materially in bringing the weed under control in New Zealand and possibly Tasmania, where several districts are infected.
