Insecticides overcome
(N.Z. Press Assn.—Copyright) GENEVA. More than 200 species of insects have now developed resistance to insecticides designed for use against them, according to the World Health Organisation. They include 105 species which carry disease to man or animals. Among these are 38 kinds of malaria mosquitoes, 19 species of mosquitoes carrying filariasis, which may lead to elephantiasis, the yellowfever mosquito, which also transmits dengue fever, the rat flea which carries bubonic plague, blackflies, houseflies, lice and cone-nosed bugs. To counter this the World Health Organisation has developed new insecticides, natural enemies of insects and genetic control.
