Mosquito Can Be Destroyed Only By Eliminating Its Hiding Places, Says Expert

That the people of every nity should unite against a common enemy—the mosquito —is the opinion of George A. Dean, Professor of entomology in, the Kanshs State Agricultural college. ’"rBy doing away wilh breeding places, such as tin cans, broken crockery, and various receptacles that hold water, by the drainage of bodies of water likely to contain immature mosquitoes, by application of oil to bodies of water that cannot be drained, or the introduction of fish in pools that cannot either be drained or oiled, millions (if mosquitoes may "be destroyed, according to Professor Dean. Water is necessary for the life of -the mosquito. The eggs which are laid on the surface of the water by the adult mosqufto. hatch in from 24 hours to several days, depending on the temperature. .The larvae issue from the lower end of the egg and wriggle about in the water. The larvae of the house mosquito rest with the tip of the abdomen at the surface of the water and the head 'hanging downward. The larvae of the malaria fever mosquito lie parallel with the surface of the water to obtain air. In from one week to ten days they change to another form—the pupae— which hive two respiratory tubes on the thorax. These pupae float in the water and transform to the adjjlt in from five to six days. The adult winters In the dormant condition. i The germ causing malaria fever has been carefully and repeatedly traced through'lts life history and it has with certainty Man found to, pass a part

of its existence in man and part in the body of the. mosquito. By the bite of the mosquito, the malarial fever organism is transmitted to man. No practical methods have been devised to destroy adult mosquitoes — all successful methods so far have been to check their number by either doing away with hiding places or by destroying the young mosquitoes.
