GRASS GRUB CONTROL
Study Of Use Of Predators
(Parliamentary Reporter)
WELLINGTON, August 3. An entomologist from the Commonwealth Institute of Biological Controls was studying the grass grub problem in New Zealand with the idea of identifying suitable areas into which predators from South America might be introduced, the Minister of Science (Mr Taiboys) said tonight.
Speaking in Parliament on the Scientific and Industrial Research vote, he said that as the grass grub was a native insect, control of it by introducing predators was likely to be less effective than if the pest itself were imported.
There were reduced residual risks in new formulations of D.DT., but many problems relating to granulated insecticides still remained to be solved. Alternatives were being studied. Much work was being done on the problem of loss of toxicity before insecticides penetrated to effective levels.
