Lethbridge Herald, The (Newspaper) - November 16, 1972, Lethbridge, Alberta Thurtday, November 16, 1972 THE LETHBRIDGE HERALD 33 The lot of the codling moth not a happy one SUMMERLAND, B.C. (CP) The lot of the codling moth is not a happy one but it's bring- ing smiles to the faces of apple and pear growers in British Col- umbia's Okanagan valley. The larvae of the codling moth pose a major threat to orchards in the area and re- search scientists are developing methods to reduce, or perhaps eliminate, the moth. One method is to raise sterile males and the other is by using a chemical substance to attract the moths in "sex traps." A specially designed building near the shores of Lake Okana- gan at the federal research sta- tion here is being used to raise codling moths a day. Eric Brinton, one of the de- signers of the program, said moths are raised in the building to be irradiated and then re- leased in local orchards. Irradiated males are sterile. Special equipment is used to raise the moths and Mr. Brinlon and Bill Tewnion, also of the station, recently received an award from the federal public service for developing part of the system. "Within a few hours after they emerge, adult moths are irradiated by cobalt 60 and on their way la helicopters from which they're released over the Mr. Brinton said. The chemical sex traps, used to measure the insect popula- tions in the orchards, are using a new type of chemical called pheromone. Dr. Harold Madsen described pheromone power as "fantas- tic." "We put one milligram of a codling moth hardly enough to a rub- ber band about two inches by half an inch and It attracted male moths in the field for 79 he said.

Canada. Until about four years ago, oyster production off Long Is- land was in the hands of sev- eral dozen small producers, some of whom had been in the business for generations. The sales had dropped to less _ian a year and many of the long-lime oyster- men were considering where to turn for a livelihood. Business had fallen drasti- cally because lieavy floods in the 1950's destroyed the seed beds where oysters spawned in the rivers of the southern Con- necticut shore. But it was in 1968 that the techniques of acquafarming were first applied off Long Is- land to oyster growing, and big business took over. Five small family-run oyster companies banded together in that year to form Long Island Oyster Farms. Purchased by a large New York City conglom- erate type of corporation, In- mont, they developed an exten- sive network of nursery beds and growing areas here, along the southern shore of Connec- ticut and in the eastern Long Island bays, particularly around Greenport. Several other small oyster- men had already gone out of business; others with larger cap- ital expanded, particularly in the areas of Oyster Bay, Bay- ville and and they adopted techniques similar to those used at Long Island Oys- ter Farms. The aquafarming operation here is in a small bay on the back of the Long Island Light- ing Company generating plant, where water used for cooling inside the facility Is discharged into the 4.5-acre bay. Some 19 million oysters are always in the early slates of growth in the clear, .shallow water. The discharge guarantees that the temperature will never fall below 40 degrees, the point at which oysters stop growing. Inside Ihe company's labora- tories, Ihc oyslcrs are spawned, nnd the weak nnd slow-growing us are screened out while :y are still so small that ...jy are distinguishable only under microscopes. Fed on algae, wliich is also grown here, the baby oyslers are transferred out into the lagoon when they are about six weeks old. Lalcr. when more mature, they arc taken in steel nets lo one of several areas in the northern portions of the Sound for tlicir middle period of growth. Since oysters are nble to cleanse themselves of pollution, mliko some other forms of .ihclllish, they arc taken for their finnl growing stages lo the purer waters of Gardiner's Bny off Greenport, where they nrc brought to maturity. Using lliosc scientific meth- ods, Iho oyslcr farms have re- duced Ihe growth period of the oysters from four or five years lo two to two and a half.
