The bonspiel was very much enjoyed by all. BETH CORNISH-reporter Mosqiiitoe s Don't Need Blood To Reproduce Longtime Myth Dispelled Two Canada department of agricuiture scientists have dis- pelled a long-standing myth that some types of mosqujtoes need a red blood meal before (bey can lay eggs, Dr. Peter Harris and D.' R. Riorum of the CDA's Beueville, Oat, Research Institute have proven that it least two mos- quito species are not only at- tracted to insect larvae, but will feed on them and live to pro- duce viable eggs. The discovery could have im- portant nmrificaiisos in several areas of science: probably because mosquitoes have trouble sucking a meal from a squirming worm. The'mosquitoes fed on a'Wide range of sotft-bodied insects, in- cluding the larvae of a sawfly, a beetle, a-butterfly and sev- eral moths. They rejected spid- ers and earthworms. The scientists also learned that the number of effls de- have- so far been closely KtojBeii as-carriers of disease between vertebrates. However, 'the new discovery adds insects to the list of possi- Me disease sources. Insects may actually be a large, unsus- pected and convenient reservoir for diseases of vertebrates. Changes will be necessary b the methods used to deter- mine the natural hosts of mos- quitoes. This is usually done by serological analysis of the gut content of 'wild mosquitoes captured by researchers. Scien- tists usually test only the mos- ouHnes with dark or red ab- domens the ones that have fed on the red blood of verte- brates and ignore the others with pale, swollen abdomens. Because these mosquitoes were ignored, there was no possibility that invertebrate (insect) meals, which are ncmaHy yel- low, pale green or colorless, would be detected. Before the discovery, it was thought that some mosquito species in such remote areas as the Arctic were obtaining all of their blood meals from a rel- atively small number of verte- brates. It now appears likely that, where vertebrates are scarce, mosquitoes may be util- izing insect blood. One implica- tion of this is that H. would not be possible to control these mosquitoes by wiping out such wild vertebrate hosts as ground squirrels, lemmings, etc. Dr, Harris says the discovery that the Aedes aegypti and Culex UrsaHs species of mos- quito were attracted to inaect larvae was unexpected. "It was generally assumed that the nourishment needed by the adults of many species of mosquitoes lo develop eggs is by- the mosquitoes 'in- creased-with tbe protein coo- tent of their meal 'Because insects have a low- er concentration of .protein in their blood sometimes much lower than vertebrates, they as hosts Wthe production of mosquito says Dr. Harris. "Also, a'shock-like death oc curred to about 10 per cent of the mosquitoes feeding on in- sea larvae within a few hours of their meal. "We don't know why. What': more, mosquitoes that feed on he larvae of the monarch wtterfly die within three days of talcing a msal. It appears hat these larvae are poisonous to mosquitoes, just as they are to birds." Or. Harris says the Culex larsalis species of mosquito did not feed on insect larvae until they had been kept for at least two weeks without a blood meal These. same mosquitoes will feed on vertebrates within a few' days of hatching. "It is almost, certain that in- sect meals are not important for mosquitoes in regions where vertebrates are says may, how- ever, be important in the Arctic and other region! where verte- brates are scarce. "There species of mosquitoesj-esbricted to feed- ing on bisects, just as there are species feeding only 'on birds or only on amphibians and rep- tiles." No matter what you plant this year, protect your income with Avadex. Perhaps this year, because more income is on absolute must, you're going to switch lo flax or rapeseed .crops and cut every possibls corner on expenses. Whatever your plans, wild oats are still going to be the major threat to your income. And Avadex is still the number one wild oot killer. (It's been proven on.the prairies for ten yeors.l As a pro-emergent herbicide, Avadex is still the only product you can use at the same time you plant.So don't lose your investment by letting wild oats take over as much as a third o( your [and, because there are no profits in wild oats. No matter what you plant, plant it with Avadex. Calendar Of Farm Events April 24 Bun Show and Sale. April 3 Mediano Hat 4-H District Public Speaking Eliminations April 3 Warner Meeting with Hon. H.

"Our work upsets those assumptions and it'opens an entirely new vista of exciting possibilities."

The discussion centred around the- government 'cost- sharing program for rehabilita- tion.
