[Standardization of a method for determining the irritability of mosquitoes (Diptera, Culicidae) to insecticides].
The method for determining mosquito irritability with insecticides recommended by the WHO has some drawbacks, which make the results less valuable. An improved method for determining the irritability is developed, in which WHO standard instruments and WHO insecticide paper are applied. It is suggested that the same specimens be used both in experiment and control, and spontaneously active females be removed from the experiment. It is recommended to calculate mosquito distribution from the degree of irritability. In determining the degree of irritability some motor activity in between flights should be taken into account. In each group average number of flights is calculated within 10 min. contact with insecticide. It is shown that a single experiment with every population is sufficient for obtaining true results if the size of experimental sample is 50 females.
