LABORATORY ASSESSMENT OF ORGANIC INSECTICIDES FOR CONTROL OF CERTAIN LEPIDOPTEROUS LARVAE
Published online by Cambridge University Press: 31 May 2012
Extract
Recent developments in the insecticide field have made available to the economic entomologist a wide variety of chemical compounds which exhibit high toxicity to certain species or groups of insects. The pyrethrins rotenone and nicotine, reinforced by the dinitro compounds and thiocyanates of prewar times, have now been joined by the chlorinated aromatic hydro-carbons: DDT, gammexane, chlordane and toxapohene.
