3 ir. Colin Curtis, Entomlogist, in his book "THE MOSQUITOES OF BRITISH COLUMBIA published in 1967 recognined that there wae a MPOTENTIAL THREAD from mosquitoes carrying encophalitide viruses, and that Culex Tarsalie is British Colurbiats principal carrier of the d iseass known aa Western Equine Encephalitis, It is this same mosquito along with Culex Pipiens (which can aleo transmit encephalitis) which has become DONE TO PESTICIDES IN CALE ORUIA. Mr. Ralph Palmer, Vector Control Officer for the Fraser Valley Mosquito Control Board, states unequivocally that he has seen no evidence of the mosquitoes in British Columbia having become immune either to DOT (which was used prior to 1957, or Malathion being used in adulticiding today, but it is evident that as far back es 1967, Dr. Curtis was aware that such a problen existed because he wrote, "ore serious is the problen arising from artificially raintained bodies such as Sewage stabilivation lagoons and og ponds, Culex Tarsalis and Culex Pipiens thrive mightily in these waters, whose high erganic content rendera most insecticides ineffective. In the light of what has happenee in California, we can assums that we nay sone Cay face the same predicazent thay Californians find thenselves in today, of having no mathod of effectively controlling mosquito populations, There are alternatives to using chenical insecticides; While it is realised that it is next to inpossitile to implement a total biological. control method imediately because of the time factor involvad, in (anywhere from 5 to 10 years); and partly due to ths fact that the insecticldesr used, DOT and Malathion, vere most effective in Killing the oredators and parasites of the moequito along with the sosquitoes. However, an integrated control rsthod, using predator insects tegether with a nirdmum of non-polluting chemicals might be the best method we have evallable to start with. We must work toward total BISLOOICAL CONTROL xy by using (&) the predators and parasites of the mrgquite as a netural control, tcgether with (b) the use of « sex attractant a3 & zeans of " gathering male rosquitoes together for the purpose of sterilizing thes with X-rays, or come form of a chenosterilant used to render then serile, or by (¢) eolective breeding whereby female rocquitoes will give birth to predominately male offspring in a ration of roughly 95 males to $ females out of every 160 nosquitoes. Sone additions! control methods could also be used, namely, ditching and cyking wherever possidle in order to eliminate some of the breeding grounds of sosjuitoes, Lakes or ponds that are too big to be altered in any way could be stocked with mosquito eating fish, etc... Tha general publte should also be instructed to elininate stagnant neols of water on their private property az well. - A growing mumber of people including sume of the world's leading scientists are becoming alarmed at what *ppears to be an almost total derendence on the use of chemical pesticides, Was Rachel Carson an hysterical alarsist (which 4a the tag some poople Place on those of us who cre becoming concerned about our rapidly daterforating enviroment) when ehe pored the question: "How could intelligent beings seek to control a fee wranted species by a rethod that contaminates the entire environment and brings the threat of disease and “death even to their om kins? xt is a well documented fuct that DOT has been found all over the world, in every living thing from roler bears in the Arctic to penguins in the Antartic, thousands of ziles away from the areas where these ponticires were originally arplied. Since we carry trace amounts of EDT and of her pesticides in our adipose Sissues, and various other organs including the brain, it has Seer impossible for the Food & Drug Directorate to set a 2ERG tolerance level of the anount they would allow in milk and o:he= foodstuffs. fs these pesticides continue to build up residues in the Inman body, the Food & try Brectarite
