6—Lancaster Farming, Saturday. August 14,1971 USDA Declares Biological War on Coreal Leaf Beetle A biological war is being waged by the U.S. Department of Agriculture against the cereal leaf beetle a foreign in vader currently threatening wheat, oat. and barley produc-' tion in this country. The cereal leaf beetle is par ticularly destructive in the United States because it has few natural enemies. USDA’s Agri cultural Research Service is at tempting to correct this imbal ance by rearing and releasing cereal leaf beetle parasites im ported from other nations. ARS scientists have found three species of tiny wasp parasites capable of adapting to condi tions in this country and are now just beginning to rear these beneficial insects in mass. The wasps inject their eggs into cereal leaf beetle eggs or larvae. Newly hatched wasp larvae eat their hosts destroying cereal leaf beetles before they can at tack food crops. During 1971, ARS and co operating State scientists re leased nearly 700,000 egg para sites at 109 locations in Illinois, Indiana, Kentucky, Michigan, New York, Ohio, Pennsylvania, and West Virginia. More than 65,000 larval parasites have been released so far this year at 11 sites in Indiana, Michigan, Ohio, and West Virginia. The egg parasite (Anaphes flavipes) is reared at ARS’ Cer eal Leaf Beetle Laboratory, Niles, Mich. The three-lined po tato beetle is a better labora tory host than the cereal leaf beetle because it lays eight times more eggs than the grain WE DO ONE BETTER HARVESTER OWNERS We will pickup and deliver your harvester knives.

Anaphes eagerly parasitize potato beetle eggs in the labora tory but prefer to attack cereal leaf beetle eggs in the field. Two larval parasites (Tetra stichus julis and Diaparsius carinifer) proved unsuitable for laboratory rearing. Instead, ARS and State agencies in the infested area cooperated to es tablish outdoor “insectories,” or rearing beds. This year, two insectories are being establish ed in Michigan, three each in Indiana and Ohio, and one in West Virginia. ARS’ worldwide search for natural enemies of the cereal leaf beetle began in 1965. But locating the parasites involved only a small part of the time and effort requqired to activate the cooperative Federal-State cereal leaf beetle parasite re lease program. After the parasites cleared through U.S. quarantines, ARS scientists began rigorous, time consuming studies to determine if each species could adapt to its new environment and if it would attack only target pests. Next, the scientists had to de vise economical methods to mass produce the beneficial species. Other projects involved synchronizing the life cycles of biotic agents and pest, and studying ecological relation ships between the cereal leaf beetle and the crops it attacks. ■ Discovered in Michigan and Indiana in 1962, the cereal leaf beetle has spread to Illinois, Kentucky, Maryland, New York, Ohio, Pennsylvania, Virginia, West Virginia, and Wisconsin.

GET MORE FROM EACH MAW! xf-- H PUTTING on extra labor during the peak seasons is mighty expensive. Finding man power at those times is difficult. Makes a lot more sense to get more work from the manpower you have ... by putting your labor force on a bigger tractor. That’s what we call workpower... the real measure of a man’s worth... whether it's your personal worth or that of a hired man. Allis-Chalmers One-Ninety and One-Ninety XT Senes 111 tractors can give you that extra measure of workpower. And the savings from covering more acres per man hour can add up to bigger profits.
