'Major Mystery' Over Myxomatosis
CANBERRA, May 9.
It would be criminal to take the great success achieved in spreading myxomatosis in NSW and
Queensland as a guide to what could be expected in normal conditions, Mr. Francis Rat- cliffe said tonight. Mr. Ratcliffe, who is director at the wild life survey section of the Commonwealth Scienti- fic and Industrial Research Organisation, is responsible for spreading the rabbit killing disease. Addressing the Canberra branch of the Royal Society, he said the disease was spread as far as was known only by the mosquito and the heavy rain and flooding late last year must have facilitated this. Next summer the CSIRO hoped to clear up several im- portant points. Among these was whether a small sandfly was responsible for the extensive spreading of the disease in Queensland in areas apparently free of mos- quitoes.
