(AP) Researchers striving to end dependence on dangerous pes- ticides are entering an era of biological control of crop- harming insects. Biological control is nature against nature. The classic technique is to encourage good bugs to eat bad bugs. Other methods include syn- thesizing a female insect's love scent, sterilizing the male of the species, or infect- ing a weevil with a virus. The biological control ef- forts arc receiving impetus from mounting evidence that excessive use of potent chemi- cals is harming the environ- ment, perhaps even endanger- ing man, and that insects are developing genetic resistance to substances that once killed them with ease. Entomologists concede, however, that they face both scientific and human prob- lems. Housewives, for example must be persuaded to buy pro- duce that is less than perfect with a worm hole. Economic bar- riers to greater use of biologi- cal control by farmers must be removed. And the suspi- cion and rivalry between the agricultural chemical industry and biological control advo- cates must be overcome. In universities and agricul- tural experiment stations across the U.S. biological con- trol is receiving more and more attention. MORE MONEY NEEDED But despite its 90-year his- tory, biological control is un- dernourished. Estimates are that agricultural chemical companies spent in excess of million on research and development in 1970 while less than million, mast of it government money, was spent on biological control research. The U.S. farmer spent an estimated million for pes- ticides last year. Comparable figures for biological control purchases weren't available. In their efforts to get good bugs to eat bad bugs, scien- tists have uncovered dozens of such predacious relationships. Ladybugs enjoy dining on aphids, tiny bugs that can kill or damage a plant, and small wasps from Latin Amer'.'a at- tack the woolly whitefly. a California orange grove Although purists object, bi- ological control also has come to mean other tricks that turn nature to man's advantage. Scientists have synthesized the chemical responsible for the female hisect's siren call of love in about two dozen species. The love scent can be used to jam the male's fe- male-seeking apparatus o r lure him into a trap where he is killed or sterilized. Other scientists are working on schemes to interfere with an insect's metabolism or re- production. Hormones that stop a young insect's growth are being studied. In the southwest, millions of steri- lized male screw-worm flies were released in the 1360s, preventing reproduction and curbing a serious livestock pest. EACH IS LIMITED Bacteria and viruses harm- less to man but deadly to cer- tain insects are being devel- oped. Experts once hoped such techniques would eliminate pesticides. But experience has shown each has limitations. Importing one bug to eat another will fail if the new insect can't adapt to the cli- mate or if its life cycle doesn't synchronyze with tho pest's. The trend now Is toward "integrated a so- phisticated blending of biolog- ical control with selective ap- plication of limited amounts of chemicals as a last resort. The goal is to reduce pesti- cide use so it no longer threatens the environment. Economic factors are a problem. Tomato growers, for exam- ple, get 95 per cent pimvorm control with biological meth- ods, 97 per cent control with chemicals. In some years, two per cent Is the difference be- tween profit and loss. Biological control often costs more than chemicals. But its proponents say it's cheaper in the long run. "Once you control a pest by biological methods, it usually is controlled said one scientist. Dy PAUL JACKSON Herald Ottawa Bureau OTTAWA Every Western oilman and Investor wheth- er he plays the low-priced stocks or the gilt-edged ones- should take a very tlosc look Indeed at the recent Science Council of Canada background study on marine science and technology. The council devotes one full in-depth chapter to the search for offshore hydrocarbons. Comparing the fledgling Cana- dian offshore industry to the highly-developed one on the U.S. Gulf Coast, it sums it up by saying: "This is billion dollar busi- When usually staid and reserved scientists and other op professionals start to bub- ile over with exclamation marks and comments like tiiat iou know you are on to some- liing good. And so you are. Offshore oil and gas in Canada promise to yield developments at least as .mportant as our existing pe- troleum producing industry. Perhaps many times bigger. About half of the promise arises from waters surrounding ,he Atlantic provinces. Inter- esting to note that this is the region in Canada most in need of economic development. The report finds there is a definite possibility that the pe- troleum industry in this region will have, within a few years, .he same kind of dramatic im- sact on the economic life of ;he Atlantic provinces as it has already had on Alberta. We all know what kind of an impact that was. The council sees millions on millions of dollars in invest- ment. Creation of new jobs to be counted in the thousands. A mushrooming growth of sec- ondary' and support industries. And, of course, a surge in con- sumer spending power. Now this doesn't mean that we should all pack our bags and head for the Atlantic provinces, although some of our more en- terprising entrepreneurs might do just that. But it does mean that both businessmen and in- veslors should take a close lo'jk at developing and investing in Jie industry there. And that means even-one from the per- son who builds oil to the person who's going to sell a cup of coffee at one cent less than some-one is now doing. FORTUNES TO MADE For make no mistake about this, fortunes are going to be made in this area. Some are go- ing to be made by long estab- lished companies with years on years of experience. But you can bet your last dollar on the penny stocks that many, many fortunes are also going to re made by people with little more than an idea, lots of drive, and a very small loan nf a few dollars from tnc-ir friendly manager.

Many advances predicted in bid to conquer diabetes TORONTO (CP) Dr. Charles Best, co-discoverer of insulin, predicts significant, ad- vances in diabetes research dur- IR the next 20 years. He told a luncheon meeting of the Canadian Club of Toronto Monday that much research, in- cluding development of a way to take insulin orally, is in the ex- perimental stage now. Insulin is a hormone produced in the pancreas to control sugar in the blood. People who lack that control develop diabetes. It was 50 years ago that Dr. Best and Dr. Fredrick Banting discovered insulin at the Uni- versity of Toronto. In an interview following the address, accompanied by a slide presentation outlining th? his- tory of insulin's development, Dr." Best predicted that insulin, which now is injected into the body, will likely be taken orally in 10 to 15 years. An artificial pancreas also might be developed by then. The device, a small mechanism a similar in size to a heart pace- j plane crash 30 years ago. maker, would be placed under!

He also discussed the possibil- ity of pancreas grafting, similar to trausplanting. A tanned and healthy 72, Dr. Best is the central figure in the year-round celebration marking the 50th anniversary of insulin's discovery. Although he Is supposed io be retired, he said, he still lectures occasionally at the University of Toronto's Banting and Best In- stitute. This year he has trav- elled extensively, lecturing to symposia on insulin. Dr. Best, a grandfather, spends his spare time painting, a hobby he shared with Dr. Banting. The latter died in a out.

(CP) Walter Tose, valedictorian of the 1971 graduating class of Paris Dis- trict high school, called for n closer link between high schools and universities in his speech at recent commencement exer- cises at the school. He said stu- dents are often bewildered by the content of courses they have selected for their university de- gree. He said high schools should provide specific Informa- tion about universities and their courses and that university cal- endars should be more informa- tive.

Shop In Pincher Creek Great West Tire 1203 2 Ave. S. 328-2011 Smaller profits for Canadians LONDON1 (CP) Canadians will have to work a little harder and bank on smaller profits as they try to scale the walls of an expanded Europe. That's the consensus among businessmen and officials are impressed by the size of Prime Minister lle'alh's 112-vote ma- jority in Uie House of Commons balloting Thursday night ap- proving European Common Market membership in princi- ple. One Canadian official said he Is inclined to look on the situa- tion with cautious optimism. Tile European reaction to the American surcharge was "rea- sonable" and gave no indication that the Common Market would dive into deeper protectionism or attempt, to start a trade war with the U.S. With Britain cnlering the market there ir.ay be even moves towards more Moralized trade. This official faid lie doubted that Britain's rntry would load to any major changes in the tough European policy which en- courages expanded local food production through subsi- dies. But. there iniijhl be milder policies on industrial tariffs, especially if current American jv.iUi'lionism is moderated through sumo possible transat- lantic By I he time tho British transi- tional period ends in I'.iT.'l, when, if she enters, tariffs would totally aligned will) those In Europe, may on en- tirely different ball the official said. "There is no reason why Ca- nadian companies can't sell to an enlarged Common Market but we've got to learn to do things cheaper." Other representatives as well suggested Canadian secondary industry may be hardest hit once Britain joins Europe. In terns of total exports, Can- ada's sales to Britain only amount to about eight per cent. And about one-half the ship- ments won't be affected by the higher British tariffs Hint will follow after the planned five- year Market transitional period. But wilh the U.S. 10-pcr-cent import surcharge working against expansion of Canadian manufactured goods to that prime market, n number of Ca- nadian firms are reported re- viewing old and well-tried mar- kets on this side of the Atlantic. However, the Canadian sec- ondary industry producing man- ufactured items faces a difficult and uncertain period. Canadians will have to concentrate harder on pricing and inventiveness in producing Hens which his com- pclilors may not be turning out. mi; VOTATOKS FORT FRANCES, Onf.
