Abstract: Objective To study the evaluation methods of larvicides registration and field test.Methods Larvae were collected from breeding sites in the external environment or adult mosquitoes were trapped to oviposit in man-made areas.Results The relative population index(RPI)of larvae from breeding sites was under 5 after treatment by 1%temephos granules for 4 weeks,which had a good control effect.RPI of larvae from wasted tyres was also less than 5 after treatment for 4 weeks,while it was under 10 after treatment for 3 weeks in cement pool.Conclusion The field control effect and registration of quick-acting insecticides could be evaluated by the above mentioned two methods.
