The Seaforth News, 1961-01-05, Page 3That busy Bee Guards Its Secret rtbeeswould fly out into the fields and eat from hunger, W- aged of ,merely collecting food and carrying it heels to the hive, Dr. Lonnie Standifer's task would be simple, y For four years Dr, Standifer has been seeking a substitute for natural pollen which would nourish bees through the winter when no flowers bloom. Com- mercial beekeepers engaged in . the same search for centuries. But they had neither the scien- tific training nor the facilities with Which the problem is being attacked at the Southwestern Bee Culture Laboratory, a Unit- ed States Department, of Agri- culture center on the University of Arizona campus, After testing 700 possible pol- len substitutes with slight sue - cess, Dr. Standiferhas shifted his apniroach to an angle whirls has apparently not occurred to other researchers. He is tearing pollen proteins -apart into their constitutent amino acids, and trying to duplicate them with amines from other sources. Why should apiarists be in- terested in artificial pollen? The answer is easy for anyone who knows even a little about bees. He knows that the workers eau. usually store enough honey to last a large colony through the cold season: If they don't the beekeeper oan supply sugar water or some other acceptable sweet. But pollen is just as essential as sugar in a bee's diet, and often it cannot he stored in quantities sufficient for a long, hard winter. Even in mild climates a cote-, ny is likely to emerge into spring in greatly .weakened con- dition. The first few weeks of warm weather must be spent in rebuilding its numbers. If a colony could end the win- ter with a full complement of worker bees. They could start immediately to' gather honey and the apiarist could begin his hive robbing sooner, Furthermore, if he could, set out something that would suit them as well as pollen from blossoms, more workers could concentrate on collecting the nectar that becomes honey when processed insome mys- teriqus apian way. Not long after he was gradu- ated from Prairie View A&M College in Texas, Dr. Stenciller became a member of the Bee Culture Laboratory staff and, was assigned to nutrition and pollen studies. Where he mulled over how he might test artificial pollens, he remembered some. THE BOMB — This is a recently released photo of the atomic bomb of the type which oblit- erated Hiroshima in World War, II. it is 28 inches in diameter, 120 inches long, 9,000 pounds. thing he had learned In col- lege about the domestic) bee 1-fe could not simply set one of his synthetics near a hive and ob- serve hew well the bees seemed to like it. The chances were that they wouldn't touch it if any real pollen were at hand. A bee's habits are different from those of almost any other insect or animal. Nearly all others eat where they find food. Some that store provender, like the squirrel, will satisfy their hunger on the spot before start- ing the day's collecting. Only. when outside food is scarce will they feed inside their nests or caves, writes Ernest Douglas in the Christian Science Monitor. But a bee never consumes a morsel outside the hive. It col- lects from instinct alone, and usually only what its instinct says will be useful to the colony. But if no nectar or pollen is available, itmay collect some- thing as useless as coal dust or an experimental pollen sub- stitute, With help from. Dr, A, H, Kemmerer and Dr. William Mc- Caughey of . the University, of Arizona human nutrition depart- ment, Dr. Standifer devised his own system for testing his sub- stitutes. He began confining young bees, captured just alter hatching andbefore they in- gested any food, in special small cages. "Controls" were fed natural pollen, Other caged lots of 75 • were fed various substances that might do in place of pollen. Effectiveness of the substitutes was gauged by longevity of the bees and development of the pharyngeal gland, usually called the food gland. Unless a bee is well nourished, that organ in its head does not grow. This method was slow and tedious and of the 700 s u b - stances tried not one proved fully satisfactory. The best is egg albumen reduced to a pow- der; skimmed -milk powder, se- same seed meal, and soy flour are almost as good. Dr. Standi- fer, however, is notwilling to recommend any of these. Again, after conferences with Dr. Kemmerer and Dr. Mc- Caughey, the decision was made toshift this line of research mainly to chemistry. Pollen is useful to the bee because of its protein. Every protein is made up of 21 or 22 different amino acids, and in no two proteins are these acids put together in the same pat- tern. Now Dr. Standifer is extract- ing proteins from pollens known to be favourites with bees, and separating them into their ani - mo, components. One of these clays he hopes to- build a com- pound which will duplicate ' a pollen' protein, But he admits that even then he may be far from the goal. There may be some 'unidentifi- able "growth factor" in pollen that is indispensable to bees. Dr. Kemmerer, incidentally, be- lieves that there is some un- known factor in honey that is highly favourable to people. Dr. Standifer hopes to solve other bee -nutrition mysteries as he goes along. "Do bees need vitamins?" he asks. "We have. no evidence of it. Do they need fats? We simply don't know. What are their mineral needs and do they get them from wa- ter, nectar, or pollen? Maybe we'll find out somewhere along the road to a substitute pollen." Q. What should a man do when passing a woman in the narrow corridor of a train, so that he may avoid jostling her too much? A. He can step into an empty compartment, if there is one -- otherwise, otherwise,just flattenhimself as much as possible, face inward, against either wall, • 10.Abhor CROSSWORD 11.

TSI FALRMM 'FRONT Passers-by who saw W. L. Putman counting the leaves on a peach tree at pt, Catharines, Ont„ thought he was paying the penalty for losing a bet. But after counting 50,289 leaves, Mr. Putman, an ecologist with the Canada Department of Agriculture, announced that a mature peach tree may harbour more than five million European red mites at one time. His state- ment was based on an estimate of 100 mites per leaf and was for the records of the entomolo- gical laboratory where Mr. Put- man works, The European red mite is one or the most serious pests of fruit trees in Canada. * * * A small penetration of Cana- da's defences against invasion by foreign pests was achieved by the European chafer last sum- mer, in the Niagara district of Ontario, reports Dr. C. W. Far. stad, Director of the Plant Pto- Lection Division. A counter-attack withsoil treatments of dieldrin was mounted and it is hoped that the enemy has been checked. However, as the chafer is hard to keep an eye on, further re- ports on this aspect are awaited. * * * Evidence of the invasion was found when traps set in the Niagara Falls area for Japanese beetles were found to have caught not only the Japanese beetles but several specimens of the European chafer. This insect is a pest of cereal and grass crops andhas apparently be- come established :in United States territory not too far from the Canadian border. It' is not known how the chafer made its way across the border. It is thought to have reached the United States from Europe about 20 years ago in earth clumps attached to nurserystock roots. 4, * *. Canadian examination of in- coming vehicles carrying agri- cultural products is regularly made to prevent the importation of insect pests, and fumigation is often required where there is ground for suspicion. The Unit- ed States authorities have fought the chafer from one out- break to another and their ef- forts have assisted in keeping it out of Canada to date. * * * When the insect was found in July of this year field men of the Plant Protection Division tool{ up vigil under trees in the area to check the severity of the attack by observing the evening flights of the chafer. They con - eluded that the outbreak was confined to a small area. Twenty acres of turf adjoining the Lower Arch Bridge at . Niagara Falls were treated with 30 pounds of 10 per cent dieldren granules per acre, in an attempt to extermination. * * * Delimiting areas of infestation is difficult, Dr. Farstad points out, in view of the nocturnal habits of the adults, coupled with the fact that little, if any. feeding damage can be observed on " foliage of trees or shrubs. Adults emerge in June and July and make short flights at dusk from the ground to the nearest trees, buildings or posts where they remain for the night- and mate. At dawn they drop back to earth and into the soil for the day, Eggs are laid in the ground and the larvae feed on the roots of a wide range of plants with erne generation a year. , The area in which the chafer was found will be -kept under close observation by the Niagara Fells- staff in 1961 to check on the effectiveness of the control measures applied. * * * Eradication of weeds by her- bicides is a long term under- taking, tests at the Indian Head Experimental Farm have shown. E. V. McCurdy, field husban- dry expert, says treatments with herbicides for 14 years, applied annually to two wheat crops and to summerfallow in a three-year rotation, have not greatly "reduced the numbers of weeds in treated as compared with untreated' plots. * * The treatment of summer - fallow, he said, was expected to reduce the number of cul- tural. operations but proved of little value because of the growth of volunteer grain. An ester and an amine of 2,4-D and an ester of MCP were applied annually at two rates — a light rate against suscep- tible weeds and a heavy 'rate against those more difficult to control. Each treated plot was compared with an untreated one. r * * Weed counts taken in 1960 in- dicate a noticeable reduction in the number of susceptible an- nuals, such as stinkweed and lamb's quarters, and some re- duction in the number of Rus- sian thistle, particularly in the plots where the heavy rate was used. The results indicate that dor- mant weed seeds plus the few weeds that escape the herbicide treatments, togther with pee - sible re -infestations by wind and implements. a r e sufficient to keep the potential weed popu- lotion only a little below that of untreated plots.. As a test of the cumulative effect Of the herbicide 'treat-= meats, part of each summer•- fallow plot was left unworked in 1960. Weeds were abundant on all plots, much more so than expected after almost 100 per cent control of susceptible weeds during the past 14 years, The . treated plots had fewer weeds than the untreated ones; however, it is evident that her- bicide treatments will have to be continued for an indefinite period, Ancient Persian Rug Patterns Carpet -weaving, the craft for which the Persians are most re- nowned in the West, has been practiced in the province of Pars for at least a thousand years; en anonymous Persian geogra- irher of the tenth century men- tions rugs as one of the stable industries of that district, What those ancient carpets were like we have no means of knowing, but in a land as conservative as Persia traditional designs per- sist unchanged through many generations and it may well be that the characteristic "Shiraz" patterns of the present day ge back to the dawn of history. The term "Shiraz" is itself a misnomer, for whereas Shiraz is a very important emporium for the buying and selling of car- pets, the city itself has no rug workshops; the wares trafficked in are produced in the scattered villages of Fars, and . by the Qashqai and Khamseh tribesmen dwelling in their tents to the northwest and southeast of the city. The present level of output has been estimated at some 30,- 000 pieces annually. These rugs, the largest tribal manufacturers of their kind, are woven on the ground -loom and seldom exceed a width of four feet, for a loom - beam longer than five' feet is too heavy and cumbersome to trans- port.

Barclay Warren. 0.D; The Gospel of the Son of God John 1;1-14; 20:30-31. This is the first of fourteen lessons from the Gospel as re- corded by John, It was written later than the Synoptic Gospels and records chiefly teachings and deeds of Jesus in Jerusalem. Matthew and Luke each tell of the birth of Jesus, showing clearly that' He was born of the Virgin Mary. Both Mary and ' Joseph were of the House of David, John shows that Julia was God come in the flesh In fact, the great purpose of the Gospel is to emphasize the Deity of Jesus Christ, This is stated in the following passage, (Jelin 20:31), which is our Memory Selection, "These are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through His name." Here are some of the evi- dences that Jesus Christ woos. Divine, as set forth in our les- son. In the beginning He was with God, He created all things. He was the Light that liglateth every man that cometh into the world. His power as Saviour is vividly expressed in the follow- ing: "As many as received Him, to them gave He power to be- come the sons of God, even to them that, believe on His name." "Power to become." That is what we need. We make good resolutions but we can't keep them. "All have sinned and come short of the glory of God:" We need a power bigger than ourselves, Sin shackles us, Here- in is the Gospel that Jesus will give us the power we need if we believe in Him. We are not saved by our good works ,or our church membership. We become the sons of God when We com- mit ourselves fully to Jesus Christ and trust Him to save us. We would do well to read through the Gospel of John sev- eral times during this quarter. Our lives will be greatly en- riched as we view the ministry of Jesus through the eyes of John, the Apostle who was the closest to Him. John was one of the three who were with Jesus on specially sacred occa- sions. Jesus committed Mary to John's care while He was on Ge cross, lie was inspired of od to write this Gospel. t Peace(?) On Earth in Latin America Cuba isn't the only place in Latin America where guns and brickbatts have become the latest in men's fashion accessories. After tense hours when the fate of the Guatemalan government was threatened by rebels, loyal troops finally captured or drove into the hills a group of insurgents. Part of the captured booty included truckloads of rifles, ammurrtion and other military gear (top photo). Meanwhile, in Venezuela, the liberal Betancourt regime ',had ' massive Communist inspired riots on its hands. In Caracas, the capital city, soldiers fired on rioters, driving the mobs ahead of them down a street near the city university (lower photo).
